In order to solve the problem that the PT camera is more complex in structure and causes the volume of the PT camera to be large, the embodiment of the application provides a camera which comprises a first lens component, a second lens component, a front cover and a reflecting mirror component.

Fig. 1 is a perspective view of a camera 10 according to an embodiment of the present application. Fig. 2 is a front view of the camera 10 according to the embodiment of the present application. Fig. 3 shows an exploded view of the camera 10 shown in fig. 1. As shown in fig. 1 and 2, the camera 10 according to the embodiment of the present disclosure may include, but is not limited to, a housing assembly 11 and a host 12 respectively housed inside the housing assembly 11. The host 12 includes a first lens assembly 13, a second lens assembly 14, and a mirror assembly 15. The second lens assembly 14 is used to capture images of the monitored area and may be referred to as a panoramic lens assembly. The first lens assembly 13 is used for performing detail photographing or enlarged photographing on an image photographed by the second lens assembly 14 and may be referred to as a detail lens assembly. The mirror assembly 15 is located on the optical path of the light incident on the first lens assembly 13, and is used for reflecting the light to the first lens assembly 13. In this manner, imaging can be achieved by reflection of light by the mirror assembly 15.

Wherein, the angle of view of the first lens assembly 13 is smaller than that of the second lens assembly 14. In this way, the range of the monitoring area shot by the second lens assembly 14 covers the range of the monitoring area shot by the first lens assembly 13, so that detail magnification of the image shot by the second lens assembly 14 can be realized. The first lens assembly 13 includes a first lens 132, and the first lens 132 is tiltable. The mirror assembly 15 is horizontally rotatable. The second lens assembly 14 is not movable, as will be described in detail below. As further shown in fig. 2, the orthographic projection of the optical axis 141 of the second lens assembly 14 and the optical axis 131 of the first lens assembly 13 on a horizontal plane are perpendicular to each other. In this way, when the first lens assembly 13 is in the horizontal position, the first lens assembly 13 and the second lens assembly 14 can be in the first direction W and the vertical direction, and the volume of the camera 10 can be reduced as much as possible. The first direction W may be the first direction W and may be a left-right direction.

As shown in fig. 1 to 3, the housing assembly 11 includes a front cover 16, and the front cover 16 is disposed outside the main body 12 to protect the main body 12 and facilitate light to enter, so as to capture images. The front cover 16 is provided with a first through hole 161 and a second through hole 162. The first through hole 161 is configured to allow light to enter the first lens assembly 13, and may be referred to as a first window. The second through hole 162 corresponds to the second lens assembly 14, is configured to allow light to enter the second lens assembly 14, and may be referred to as a second window. The first through hole 161 is located above the second through hole 162, and the first through hole 161 and the second through hole 162 are arranged up and down such that the first lens assembly 13 is located above the second lens assembly 14, and the area of the first through hole 161 is larger than that of the second through hole 162. The area of the first through hole 161 is determined by the mirror and the first lens assembly 13, and the area of the second through hole 162 is determined by the second lens assembly 14.

The vertical dimension of the first through-hole 161 is greater than the vertical dimension of the second through-hole 162, and the horizontal dimension of the first through-hole 161 is equal to or greater than the horizontal dimension of the second through-hole 162. In this way, the area of the first through hole 161 receiving light is larger than the area of the second through hole 162 receiving light, which is more advantageous for the light of the mirror assembly 15 to enter, and the second through hole 162 is smaller than the first through hole 161, which is also advantageous for the miniaturization of the device volume. As shown in fig. 2, the mirror assembly 15 is located on the optical path of the light incident on the first lens assembly 13, and enlarges the visible area. The mirror assembly 15 includes a mirror 151. The reflective mirror 151 is disposed corresponding to the first through hole 161 and configured to reflect light incident through the first through hole 161 to the first lens assembly 13. Therefore, the first lens assembly 13 and the second lens assembly 14 realize double-lens image shooting, the reflecting mirror 151 realizes light ray incidence of the first lens assembly 13, the visible area is enlarged, and the structure is simple.

Further, the first lens 132 and the reflector 151 are respectively disposed in the first through hole 161, the reflector 151 extends longitudinally, and the first lens 132 faces the reflector 151. Therefore, the reflector 151 extends vertically, which is beneficial to the incidence of the light rays into the first lens 132 when the reflector 151 rotates horizontally, and the first lens 132 can tilt, so as to realize horizontal shooting and tilting shooting of the first lens assembly 13. The reflecting mirror 151 may have a rectangular shape. The use of a rectangular reflector 151 saves space and cost compared to a circular reflector 151. For example, the rectangle may be rectangular. The long side of the reflecting mirror 151 may extend horizontally, and the short side of the reflecting mirror 151 may extend longitudinally (vertically). For another example, the rectangle may be a square.

Fig. 4 is a perspective view of the mirror assembly and the first lens assembly 13 in the camera 10 shown in fig. 1. Fig. 5 is a front view of the mirror assembly and the first lens assembly 13 of the camera 10 shown in fig. 1. As shown in fig. 4 to 5, the mirror assembly 15 further includes a horizontal rotation structure connected to the mirror 151. The horizontal rotation structure is configured to drive the mirror 151 to rotate horizontally to achieve horizontal rotation of the mirror 151. The horizontal rotation structure may include, but is not limited to, a horizontal rotation motor 21. The horizontal rotation motor 21 is connected to the reflecting mirror 151, and the horizontal rotation motor 21 drives the reflecting mirror 151 to rotate horizontally. Wherein, the horizontal rotation motor 21 and the second lens assembly 14 are located below the reflecting mirror 151, so that the horizontal rotation motor 21 and the second lens assembly 14 are located on the same side in the up-down direction of the reflecting mirror 151. When the horizontal rotation motor 21 rotates, the mirror 151 is driven to rotate horizontally. In this way, the first lens assembly 13 does not need to rotate horizontally, and the mirror assembly 15 can rotate horizontally to present the image of the monitored area on the first lens assembly 13 through the light reflection of the mirror 151.

Continuing with FIG. 5, the horizontal turning motor 21 may be a direct drive motor. In this way, the motor shaft 211 of the horizontal rotation motor 21 is directly connected to the rotation shaft 157 of the mirror assembly 15 without any other transmission member therebetween. Therefore, the horizontal rotating motor 21 is used as a power source to directly drive the reflector component 15 to be driven to move, the transmission of other transmission parts is reduced, the cost is saved, and the miniaturization of the structure is facilitated. And simultaneously, the horizontal movement of the reflecting mirror 151 is realized, and the monitoring range of the camera 10 is effectively improved. Continuing with FIG. 5, the mirror 151 includes first and

second sides

153, 154 opposite in the first direction W. First lens 132 is positioned on second side 154 toward mirror 151 such that rotational axis 157 of mirror 151 is offset from center 1512 of reflective surface 1511 of mirror 151 and is positioned adjacent to second side 154 relative to first side 153. Thus, the second side 154 of the mirror 151 is close to the first lens 132, and image distortion is small. The first side 153 of the mirror 151 is distant from the first lens 132, and the range in which imaging can be performed is wide. Meanwhile, the rotation axis 157 of the reflector 151 is offset from the center 1512 of the reflecting surface 1511 of the reflector 151, and compared with the range of the imaging of the rotation axis symmetric structure of the reflector 151, the second side 154 of the reflector 151 is shorter than the rotation axis 157, and occupies a smaller volume.

Fig. 6 is a cross-sectional view of the reflector 151 and the first lens assembly 13 shown in fig. 4, taken along the line B-B of fig. 4. Fig. 7 is a front view of the reflecting mirror 151 and the first lens 132 shown in fig. 4. As shown in fig. 6 and 7, the mirror 151 includes a first horizontal boundary position 155 and a second horizontal boundary position 156, the mirror 151 horizontally rotates between the first horizontal boundary position 155 and the second horizontal boundary position 156, and when the mirror 151 rotates from the first horizontal boundary position 155 to the second horizontal boundary position 156 and the first lens 132 is always stationary, the horizontal intersection locus 22 of the optical axis 131 of the first lens 132 and the mirror 151 deviates from the center 1512 of the reflecting surface 1511 of the mirror 151. In this way, the horizontal intersection point locus 22 of the optical axis 131 of the first lens 132 and the reflecting mirror 151 is not collinear with the center 1512 of the reflecting surface 1511 of the reflecting mirror 151, and the first lens unit 13 is horizontally rotated to capture an image of the monitored area, and the camera 10 is also miniaturized. First horizontal boundary position 155 and second horizontal boundary position 156 in FIG. 6 are merely examples, and do not define the specific locations of first horizontal boundary position 155 and second horizontal boundary position 156.

As shown in fig. 6 and 7, the reflecting mirror 151 is disposed at an initial position, for example, when an angle v between an extension line of the reflecting surface 1511 of the reflecting mirror 151 and a mirror surface extension plane when the first lens 132 is in the first direction W is 45 degrees, as the initial position. The angle of rotation of the reflecting mirror 151 at this initial position may be referred to as a horizontal angle of rotation. The horizontal rotation angle may be a negative value horizontally toward the first horizontal boundary position 155 away from the first lens 132, and the horizontal rotation angle may be a positive value horizontally toward the second horizontal boundary position 156 near the first lens 132. The range of horizontal rotation angles may be between greater than negative 15 degrees and less than positive 15 degrees.

As shown in fig. 6 and 7, the image viewing angle overlay is achieved by the horizontal movement of the mirror 151 and the vertical movement of the first lens assembly 13, wherein the image viewing angle overlay includes a horizontal viewing angle and a vertical viewing angle. Therefore, the second lens assembly 14 detects the human body linkage, and the first lens assembly 13 performs snapshot, and it is required to ensure that the angle of view of the first lens assembly 13 covers the angle of view of the second lens assembly 14 through PT movement.

The horizontal movement of the reflecting mirror 151 is realized by a direct drive mode of a motor, the movement range is ± c, and the horizontal field angle that the whole reflecting mirror 151 can cover is as follows: d = c × 2+b _h ，D≥a _h To meet the requirements, wherein, a _h Horizontal field of view, which is the field of view of the second lens assembly 14, b _h A horizontal angle of view that is the angle of view of the first lens assembly 13, and the second lens assembly 14 is larger than the first lens assembly 13. Rotating shaft 157 of reflector 151 and first lensThe optical axes 131 of the assemblies 13 are in the same horizontal plane and the closer the distance L therebetween is, the better, but the distance L is at least greater than zero in order to avoid interference of the mirror 151 with the first lens assembly 13 and influence the rotation. Thus, light can be incident through the light incident range 158 of the reflector 151, and since the reflection surface 1511 of the reflector 151 is not rotated to the back or is completely perpendicular to the first lens 132, at least part of the light incident range 158 of the reflector 151 is incident, as shown by the ellipse in the light incident range 158 in fig. 6.

As further shown in fig. 6 and 7, the vertical field angle that the entire first lens assembly 13 can cover is F = e × 2+b _v ，F≥a _v Satisfy the requirements, wherein, a _v A vertical angle of view which is the angle of view of the second lens assembly 14, b _v The vertical angle of view of the first lens assembly 13 is e, which is the range of motion of the first lens assembly 13 that can achieve vertical motion by direct driving. In this way, the full angle of view is covered by controlling the horizontal rotation of the mirror 151 and the vertical movement of the first lens 132.

As shown in fig. 7, the first lens 132 includes a first pitch boundary position 133 and a second pitch boundary position 134, the first lens 132 rotates in pitch between the first pitch boundary position 133 and the second pitch boundary position 134, and when the first lens 132 rotates from the first pitch boundary position 133 to the second pitch boundary position 134 and the mirror 151 is always stationary, the pitch intersection locus 23 of the optical axis 131 of the first lens 132 and the mirror 151 deviates from the center 1512 of the reflecting surface 1511 of the mirror 151. In this way, the trajectory 23 of the tilt intersection point of the optical axis 131 of the first lens 132 and the reflecting mirror 151 is not collinear with the center 1512 of the reflecting surface 1511 of the reflecting mirror 151, and the image of the monitoring area is captured by tilting the first lens unit 13, and the camera 10 is also miniaturized. The first and second

pitch boundary positions

133 and 134 in fig. 7 are merely examples, and the specific positions of the first and second

pitch boundary positions

133 and 134 are not limited.

Fig. 8 is a schematic diagram illustrating a first viewing angle between the reflector 151 and the first window glass 1613. Fig. 9 is a schematic diagram illustrating a second viewing angle between the reflector 151 and the first window glass 1613. As shown in fig. 8 and 9, the first through hole 161 is provided with a first window glass 1613. The first window glass 1613 may seal the reflecting mirror 151 and the first lens 132 to protect the reflecting mirror 151 and the first lens 132. The closer the rotating shaft 157 of the reflecting mirror 151 is to the first window glass 1613, the better the angle of view and the image without black edge.

As shown in fig. 11 and 12, the mirror assembly 15 includes a horizontal bearing 24, and the horizontal bearing 24 horizontally rotates the mirror 151 along with the rotation of the horizontal rotation motor 21, so as to reduce the friction force of the horizontal rotation and facilitate the horizontal rotation of the mirror 151. The horizontal bearing 24 is disposed between the rotatable end 1522 and the main housing 18, and the rotatable end 1522 rotates horizontally relative to the main housing 18 through the horizontal bearing 24. So, speculum 151 top is supported through horizontal bearing 24, and the downside rotates motor 21 through the level and directly connects and support, can drive speculum subassembly 15 and realize the horizontal motion, and overall structure stability is good like this, and power transmission is direct, and transmission efficiency is high. In addition, the horizontal bearing 24 and the horizontal rotation motor 21 are respectively disposed at the upper and lower sides of the mirror mounting bracket 152, so that the space for concentrated installation is reduced, which is beneficial to reducing the overall size of the camera 10.

As shown in fig. 11, the mirror mounting bracket 152 includes a front bracket 31 and a rear bracket 32 coupled to a rear side of the front bracket 31. The reflecting mirror 151 is held between the front holder 31 and the rear holder 32, and supports the reflecting mirror 151 while protecting the reflecting mirror 151 by the front holder 31 and the rear holder 32. The front bracket 31 includes an annular front clamping portion 311, the rear bracket 32 includes an annular rear clamping portion 321, the mirror assembly 15 includes a mounting buffer 33, the mounting buffer 33 surrounds the side edge of the mirror 151, and is clamped between the mirror 151 and the front clamping portion 311, and the rear clamping portion 321 surrounds the outer side of the front clamping portion 311 and abuts against the front clamping portion 311. In this way, the mirror 151 is pressed and attached between the front holder 31 and the rear holder 32 by the rear clamping portion 321, the mounting cushion 33 surrounds the side edge of the mirror 151 and is clamped between the mirror 151 and the front clamping portion 311, and the mirror 151 is pressed by the compression deformation of the mounting cushion 33, so that the mirror 151 is securely fixed.

Wherein the mounting bumper 33 is compressibly deformable. The mounting bumper 33 may be, but is not limited to, a rubber sleeve having a ring shape. The rubber sleeve is sleeved on the side of the reflector 151 and leaves a blank for the reflected light of the reflecting surface 1511 of the reflector 151. Thus, the mirror 151 is protected and fixed without affecting the light irradiation of the mirror 151 by preventing the mirror 151 from being affected by the rigid connection between the front holder 31, the rear holder 32 and the mirror 151.

Continuing with fig. 11, the mirror assembly 15 further includes a cushion 34. The cushion pad 34 is interposed between the rear side of the rear bracket 32 and the fastener 35 to fixedly connect the mirror mounting bracket 152 through the rear bracket 32, thereby improving the stability of the fixation. The fastener 35 may be a screw. The cushion pad 34 may be an elastic pad or a metal pad, which is not illustrated herein. Continuing with fig. 11, the horizontal rotation motor 21 for driving the mirror assembly 15 to rotate horizontally is mounted to the motor mounting bracket 28 by 4 screws to constitute an assembly.

The installation process of the installation bumper 33 and the bumper pad 34 is as follows: the mounting cushion 33 is first fitted to the side of the reflector 151, and since the mounting cushion 33 has a small hardness, it can be compressively deformed. The reflecting mirror 151 is then placed on the front supporter 31 of the reflecting mirror 151. The reflecting mirror 151 is press-fitted between the front supporter 31 and the rear supporter 32 of the reflecting mirror 151 by the rear supporter 32 of the reflecting mirror 151. Because the installation buffer member 33 has small hardness and can be compressed and deformed, the direct contact between the reflector 151 and a structural member can be avoided, the condition that the reflector 151 is fractured due to the manufacturing error of parts is avoided, and the installation rubber sleeve on the reflector 151 plays a role in installation and protection. Finally, a buffer pad 34 is mounted on the rear support 32 of the reflector 151 by screws, so that when the product is not powered on and has no motor driving, the buffer effect can be effectively achieved, and the reflector 151 can be effectively prevented from being damaged by vibration, as shown in the front of the reflector 151 in fig. 14 and the back of the reflector 151 in fig. 15.

The horizontal rotation motor 21 includes a motor shaft 211, the motor shaft 211 is a flat structure, and the motor shaft 211 is inserted into the mounting hole 1525. Specifically, a first flat position structure is arranged on the inner wall of the mounting hole 1525 of the motor connecting end 1521 along the hole axis direction. The flat structure of the mounting hole 1525 is matched with the flat structure of the motor shaft 211, and specifically, a second flat structure is arranged on the outer wall of the motor shaft 211 of the horizontal rotation motor 21 along the axial direction of the motor shaft 211. Therefore, the first flat structure is in limit fit with the second flat structure, and the horizontal rotating motor 21 can drive the reflector 151 to rotate horizontally.

As shown in fig. 11, the motor shaft 211 has a radial threaded hole (not shown), the motor connecting end 1521 includes a mounting through hole 1523 corresponding to the threaded hole, and a hole axis of the mounting through hole 1523 is perpendicular to a hole axis of the mounting hole 1525. Thus, the motor connection end 1521 is provided with a mounting through hole 1523 extending along the radial direction of the motor connection end 1521, and the mounting through hole 1523 passes through the mounting hole 1525. Therefore, the motor shaft 211 of the horizontal rotating motor 21 and the motor connecting end 1521 can be fixedly installed together through the screw 1524, and the movement angle error caused by the fit clearance of the flat position can be eliminated.

In this way, the motor output shaft 411 of the tilting motor 41 is directly connected to the lens mounting bracket 42 of the first lens assembly 13, and no other transmission component is arranged between the two. Therefore, the pitching rotating motor 41 is used as a power source to directly drive the first lens assembly 13 to move, the transmission of other transmission parts is reduced, the number of parts is small, the whole structure is compact, and the cost is low. The horizontal movement of the reflecting mirror 151 and the vertical movement of the first lens 132 are simultaneously achieved, effectively increasing the monitoring range of the video camera 10.

As shown in fig. 18 and 19, the first lens assembly 13 further includes a lens mounting bracket 42 for fixedly mounting the first lens 132. The first lens 132 is fixedly mounted to the lens mounting bracket 42. The tilt motor 41 is connected to the lens mounting bracket 42, and when the tilt motor 41 rotates, the tilt motor drives the lens mounting bracket 42 to tilt relative to the front cover 16. In this way, the tilt motor 41 is used to drive the lens mounting bracket 42 to tilt, and the lens mounting bracket 42 is used to drive the first lens 132 to tilt. Therefore, the pitching rotation motor 41 directly drives the lens mounting bracket 42, so that the lens mounting bracket 42 and the first lens 132 are pitched and rotated together, and therefore transmission components between the first lens 132 and the pitching rotation motor 41 are reduced, the structure is compact, and the occupied space is small. Thus, the lens mounting bracket 42 and the first lens 132 are fixed together, and in the pitching process, the lens mounting bracket 42 and the first lens 132 are relatively static, so that friction and the like generated by mutual movement of the lens mounting bracket 42 and the first lens 132 can be reduced, the service lives of the lens mounting bracket 42 and the first lens 132 can be prolonged, a reserved movement space and a rotating part can be reduced, and the structure is compact and exquisite.

The first lens 132 is located on one side of the mirror assembly 15 in the first direction W, the tilt motor 41 is located behind the mirror assembly 15, and the lens mounting bracket 42 extends from the first lens 132 to the rear of the mirror assembly 15 to be connected to the tilt motor 41.

As shown in fig. 19 and 20, the tilting motor 41 is located outside the main body housing 18, and the lens mounting bracket 42 is at least partially located inside the main body housing 18. The camera 10 includes a vertical bearing 44, and the vertical bearing 44 is vertically rotated at the lens mounting bracket 42 along with the rotation of the tilt motor 41, so as to reduce the friction force of the vertical rotation and facilitate the vertical rotation of the lens mounting bracket 42. The vertical bearing 44 is disposed between the lens mounting bracket 42 and the main body housing 18, and the tilting motor 41 rotates the lens mounting bracket 42 relative to the main body housing 18 via the vertical bearing 44. In this way, the first lens 132 is fixed on the lens mounting bracket 42 to form the first lens assembly 13, the lens mounting bracket 42 passes through the vertical bearing 44 on the main housing 18 and is connected to the tilting motor 41, and the tilting motor 41 can drive the first lens assembly 13 to perform vertical movement. In further combination, the reflector 151 is fixed on the reflector mounting bracket 152 to form the reflector assembly 15, the upper part of the reflector assembly 15 is supported on the main machine shell 18 through the horizontal bearing 24, the lower part is directly connected with the horizontal rotating motor 21, and the horizontal rotating motor 21 can drive the reflector assembly 15 to realize horizontal movement. This simultaneously realizes the vertical movement of the first lens 132 and the horizontal movement of the reflecting mirror 151, which is advantageous to improve the monitoring range of the video camera 10.

Wherein, the motor output shaft 411 of every single move rotation motor 41 is flat bit architecture, and the axle mounting hole of lens installing support 42 is flat bit architecture, and motor output shaft 411 inserts and locates the axle mounting hole, and the flat bit architecture of axle mounting hole and the flat bit architecture cooperation of motor output shaft 411, so through the flat bit architecture cooperation, every single move rotation motor 41 can drive lens installing support 42 and carry out the vertical rotation. Furthermore, the first lens 132 is fixed on the lens mounting bracket 42 to form the first lens assembly 13, the lens mounting bracket 42 passes through the vertical bearing 44 on the host housing 18 and is directly connected with the pitching rotation motor 41 through the flat structure in a matching manner, and fastening screws are added, so that direct drive of the pitching rotation motor 41 and the first lens assembly 13 is realized, the transmission efficiency is high, and the overall structure is reliable.

As shown in fig. 19, the video camera 10 includes a motor mount 45, and the motor mount 45 is fixed to the main body housing 18. The tilt motor 41 is mounted in the motor mounting bracket 45, and is connected to the main body housing 18 and the lens mounting bracket 42 through a motor output shaft 411 of the tilt motor 41. Thus, the pitching rotation motor 41 is conveniently fixed. Continuing with FIG. 19, the main housing 18 is provided with spindle mounting holes 181. The rotating shaft mounting hole 181 may be, but is not limited to, a circular through hole. The shaft mounting hole 181 is fitted to the motor output shaft 411. The camera 10 includes a vertical bearing 44. The vertical bearing 44 is provided between the lens mounting bracket 42 and the rotational shaft mounting hole 181. In this way, the motor output shaft 411 of the pitching rotation motor 41 can penetrate through the rotating shaft mounting hole 181 and the vertical bearing 44, so as to mount the vertical bearing 44, and the vertical bearing 44 can rotate along with the motor output shaft 411.

As shown in fig. 19 and 20, a limiting protrusion 1811 is protruded from the inner wall of the rotating shaft mounting hole 181. The stopper boss 1811 serves to restrict the displacement of the seal ring 51. The camera 10 includes a sealing ring 51, a sealing pressing plate 52 and a bearing pressing plate 53, the sealing pressing plate 52 is fixed at one end of the rotating shaft mounting hole 181, the sealing ring 51 is clamped between the sealing pressing plate 52 and one side of the limiting protrusion 1811, the sealing ring 51 is arranged around the rotating shaft mounting hole 181 and the lens mounting bracket 42, the bearing pressing plate 53 is fixed at the other end of the rotating shaft mounting hole 181, and the vertical bearing is clamped between the bearing pressing plate 53 and the other side of the limiting protrusion 1811.

The seal ring 51 is a skeleton seal ring 51, the skeleton seal ring 51 is stationary relative to the host casing 18, and the skeleton seal ring 51 is in interference fit with the lens mounting bracket 42. Thus, the sealing manner of the skeletal sealing ring 51 can provide a good and stable damping force and effectively reduce the shaking amount in the motion stop state. Wherein, the skeleton sealing ring has a certain interference with the rotating shaft mounting hole 181 of the first lens assembly 13, so as to provide a more stable damping force.

Continuing with fig. 19, the camera 10 further includes a vertical photovoltaic panel 54 and a vertical photovoltaic baffle 55. The vertical electro-optic plate 54 may detect the angle of rotation of the first lens 132. The vertical photovoltaic panel 54 may limit displacement of the vertical photovoltaic panel 54 in the first direction W. The vertical photoelectric plate 54 is sandwiched between the bearing assembly and the vertical photoelectric barrier 55, and the vertical photoelectric barrier 55 is fixedly connected to the main housing 18. In this way, the vertical photoelectric plate 54 and the vertical photoelectric barrier 55 rotate together with the motor output shaft 411 to detect the rotation angle of the lens mounting bracket 42, and further detect the rotation angle of the first lens 132. The motor output shaft 411 of the pitching rotation motor 41 corresponding to the vertical photoelectric plate 54 has an initial position, and the vertical photoelectric plate 54 can rotate a specific angle in cooperation with a photoelectric switch (not shown). The photoelectric switch rotates by a specific rotation angle, for example, 15 °, 30 °, 45 °, or the like. The photoelectric switch has a transmitting end and a receiving end, and when the vertical photoelectric plate 54 rotates to the corresponding photoelectric switch, the light transmitted from the transmitting end to the receiving end can be shielded, so that the position where the motor output shaft 411 rotates can be recorded, and the rotating angle can be recorded. Continuing with fig. 18 and 19, the camera 10 includes a weighted assembly 43 for changing the center of gravity of the first lens assembly 13.

Referring to fig. 5, and continuing with fig. 16, 18 and 19, the weight assembly 43 includes a first end 433 connected to the tilt motor 41 and a second end 434 opposite the first end 433, the mirror assembly 15 includes a first side 153 adjacent to the first lens 132 and a second side 154 opposite the first side 153, and the second end 434 extends beyond the second side 154 in the first direction W. In this way, the weight assembly 43 protrudes from the second side 154, and is disposed outside the main housing 18, which is also more convenient for installation. The counterweight component 43 and the first lens 132 are located on two opposite sides of the pitching rotation motor 41 in the first direction W, the counterweight component 43 is connected to the motor output shaft 411, and the pitching rotation motor 41 drives the counterweight component 43 and the first lens 132 to pitch and rotate in the same direction when rotating. In this way, the counterweight assembly 43 is mounted on the other side of the first lens assembly 13, the counterweight assembly 43 is also connected with the first lens assembly 13, and the counterweight assembly 43 and the first lens 132 are respectively located on two opposite sides of the motor output shaft 411, so that the center of gravity of the whole first lens assembly 13 is located at the axial position supported by the vertical bearing 44, and therefore the shaking amount of the first lens 132 can be reduced, and the driving force of the pitching rotation motor 41 can be effectively reduced. As shown in fig. 18 and 19, the weight assembly 43 includes a weight portion 431 and a mounting portion 432 connected to the weight portion 431, the mounting portion 432 is connected between the motor output shaft 411 and the weight portion 431, and the weight portion 431 is farther from the motor output shaft 411 than the mounting portion 432 is in the first direction W.

The lens mount bracket 42 includes a lens bracket portion 421 to which the first lens 132 is mounted, and a connection portion 422 connected between the lens bracket portion 421 and the motor output shaft 411. The lens holder 421 is farther away from the motor output shaft 411 than the connecting portion 422, and the lens holder 421 is used for mounting and supporting the first lens 132. The connection portion 422 is used to transmit the force of the motor output shaft 411 of the tilting motor 41, and the lens holder portion 421 and the connection portion 422 may be assembled. The lens holder portion 421 is integrally formed with the connecting portion 422. The mount section 432 and the connection section 422 extend in opposite directions along the axial direction of the motor output shaft 411 from the opposite sides in the radial direction of the motor output shaft 411, respectively, and the lens holder section 421 extends forward from the connection section 422. In this way, the distance between the center of gravity of the weight assembly 43 and the motor output shaft 411 is proportional to the distance between the center of gravity of the first lens 132 and the motor output shaft 411, and the weight assembly 43 and the motor output shaft 411 of the pitching rotation motor 41 rotate together with the motor output shaft 411. Because the first lens 132 is disposed on the eccentric rotating shaft, the motor output shaft 411 is used as the rotating shaft in the embodiment of the present application to rotate, the driving force of the pitch rotating motor 41 is too large, and the counterweight component 43 is used to support the axis position of the center of gravity of the first lens component 13 at the vertical bearing, thereby effectively reducing the driving force of the pitch rotating motor 41 and reducing the lens shaking amount during the movement process.

Wherein the weight portion 431 includes a plate-shaped structure of a regular shape or a block-shaped structure of a regular shape. Such a regular shape facilitates the arrangement of the weight portion 431, and at the same time, stable weight during vertical rotation of the weight portion 431 can be realized. Regular shapes are for example spheres. The regular shape is, for example, a hexahedron. This is not exemplified. The weight 431 is vertically symmetrical with respect to the mounting part 432. The weight 431 extends rearward from the mounting portion 432. The counterweight assembly 43 is located outside the main machine housing 18. Thus, the weight 431 is easy to install. The mounting portion 432 is located at the rear side of the connection portion 422. The mounting portion 432 and the connecting portion 422 are vertically symmetrical with respect to the radial direction of the motor output shaft 411. Thus, the installation of the counterweight assembly is facilitated. The weight portion 431 protrudes rearward and forward from the mounting portion 432, and is symmetrical forward and rearward with respect to the mounting portion 432. Therefore, the counterweight component is simple in structure, and counterweight can be realized more favorably through a symmetrical structure. The lens holder portion 421 is vertically symmetrical with respect to the connection portion 422. Therefore, the structure is simple and the arrangement is convenient. Continuing with fig. 18-20, the weight assembly 43 includes a vertical cushion 46 fixedly mounted to the mounting portion 432 for providing effective cushioning when the product is not powered and is not motor driven. And, when configuration subassembly 43 rotates along with motor output shaft 411, provide cushioning effect, reduce the mutual extrusion damage between the part.

The first space 165 is left with a space in which the reflecting mirror 151 horizontally rotates, and thus, interference with the front cover 16 is prevented. A second space (not shown) is provided between second hole edge 1612 and second cover sidewall 164. The second space (not shown) is left with a space for the first lens 132 to tilt and rotate, so as to avoid interference with the front cover 16, and the first lens 132 can be tilted more flexibly. Wherein the first space 165 is smaller than the second space (not shown).

The pitch rotation motor 41 is located at the rear side of the main body housing 18 opposite to the mirror 151. The lens mounting bracket 42 connects the tilt motor 41 and the first lens 132, and the tilt motor 41 drives the first lens 132 to tilt through the lens mounting bracket 42. A harness escape space 62 is provided between the lens mounting bracket 42 and a side wall of the host housing 18 in the first direction W near the lens circuit board 61, the harness escape space 62 is a space for avoiding interference of the harness 64 with other components, and the harness escape space 62 is communicated with the second space.

As further shown in fig. 26 and 27, a wire winding assembly 63 is provided outside the main housing 18. The wire winding assembly 63 is used to provide a winding fulcrum for the wire harness 64.

Thus, the wiring harness 64 is fixed through the tail 1322 of the first lens 132, the routing layout of the wiring harness 64 is adjusted, and the influence of the vertical swing of the first lens 132 and the lens mounting bracket 42 on the service life of the wiring harness 64 is avoided, so that the service life of the wiring harness 64 is prolonged. Moreover, the harness 64 can be retracted from the pitching rotation motor 41, and does not interfere with the pitching rotation motor 41, thereby improving the life of the harness 64 and the safety of the harness 64. The wiring harness 64 may be used for signal lines for transmitting signals or power lines for supplying power, among others. Alternatively, the wire harness 64 may be an FPC (Flexible Printed Circuit board) wire, also called a flex cable. The wiring harness 64 is mainly used for transmitting high-speed signals such as images, and the wiring harness 64 is used for connecting the first lens assembly 13 and the second lens assembly 14 main boards on the camera 10. Due to poor bend and twist resistance, they are generally used in relatively static connection schemes. Meanwhile, the coaxial line is cancelled in the wiring harness 64, and on the premise that the service life of the wiring harness 64 is prolonged, the cost is obviously saved.

Fig. 28 is a schematic view of the wiring harness 64 and the lens mounting bracket 42 shown in fig. 27. Fig. 29 is a partially enlarged view of J shown in fig. 28. As shown in fig. 28 and 29, the lens mount bracket 42 includes a bracket back surface 423 facing the harness escape space 62 in the first direction W, where the harness 64 is fixed to the lens mount bracket 42 in order to allow the part of the harness 64 to be in a relatively stationary state with respect to the first lens 132. The camera 10 includes a restraint harness mount 65 for restraining the wiring harness 64 from running. The position-limiting harness seat 65 is used for limiting the movement of the first harness segment 641. The position limiting harness seat 65 is disposed on the bracket back 423.

Therefore, the limiting harness seat 65 arranged on the lens mounting bracket 42 is used for limiting the trend of the harness 64, so that the harness 64 can be tightly attached to the outer wall of the lens mounting bracket 42, and interference with other devices is avoided.

As shown in fig. 26 and 28, the second wire harness segment 642 includes an extension segment 6421 and a winding segment 6422 connected to the extension segment 6421.

In this manner, the extension 6421 may be swung to extend or shorten as it moves with the first lens 132 and the lens mount 42. In addition, the extension 6421 leaves a corresponding space to ensure the vertical swing of the first lens 132, and can effectively avoid the twisting of the wire harness 64 during the movement process, thereby prolonging the service life of the wire harness 64. And the winding section 6422 is wound on the winding assembly 63 to change the movement of the wire harness 64 from free swing to spiral movement in the tangential direction of the winding assembly 63, and after the winding assembly 63 is wound on the winding section 6422, the positioning point provided at the end thereof is fixed to prevent the displacement of the winding section 6422.

Thus, the harness guide hole 651 is used to pass the harness 64 therethrough, which is advantageous for restraining the harness 64 and fixing the harness 64.

Continuing with FIG. 29, the restraint harness seat 65 includes a catch 652, the catch 652 including a catch connection 6521 and a restraint catch 6522 connected to the catch connection 6521. The snap connection portion 6521 is fixed to the back 423 of the bracket, the limit snap hook 6522 is connected to one side of the connection portion departing from the back 423 of the bracket, and the wire harness 64 enters the limit harness seat 65 from the limit snap hook 6522.

Therefore, the first limit harness seat 66 and the second limit harness seat 67 can limit the moving range of the harness 64 as much as possible while fixing the routing direction of the harness 64, so as to avoid interference with other devices in the moving process, for example, avoid the movement of the harness 64 relative to the first lens 132 and the lens mounting bracket 42, and improve the stability of the harness 64.

As further shown in fig. 28 and fig. 29, the camera 10 includes a fixed harness seat 68, the fixed harness seat 68 is disposed on the bracket back 423, the fixed harness seat 68 is far away from the lens circuit board 61 and close to the wire winding assembly 63 relative to the position limiting harness seat 65, and one end of the first harness segment 641 far away from the lens circuit board 61 is fixed on the bracket back 423 through the fixed harness seat 68. Thus, the wire harness 64 is restrained from moving, and the wire harness 64 is prevented from moving. Wherein, the wire harness 64 after passing through the wire winding assembly 63 is connected to the main board, the end of the wire harness 64 located at the wire winding assembly 63 can be fixed by using the fixed wire harness seat 68.

The installation process of the first lens and the wire harness is as follows: the first lens 132 and the lens mounting bracket 42 are fixed by screws, and the wiring harness is inserted into a corresponding seat of the lens circuit board 61 at the end 1322 of the first lens 132. The routing path of the wiring harness is restrained by the two wiring harness 64 buckles, and meanwhile, the phenomenon that the lens drives other devices to generate interference in the movement process of the wiring harness is avoided. After the wiring harness 64 is inserted into the seat, the wiring harness 64 is firstly buckled by the first wiring harness 64, so that the wiring harness 64 can be tightly attached to the lens mounting bracket 42; and then the wiring harness passes through the first limiting wiring harness seat 66 and the second limiting wiring harness seat 67 according to a preset wiring path, and the wiring harness between the first limiting wiring harness seat 66 and the second limiting wiring harness seat 67 is in a form of being tightly attached to the lens mounting bracket 42, so that the main purpose of the wiring harness is to avoid interference with other devices caused by free swing of the wiring harness 64.

Fig. 30 is a side view of the harness 64 and lens mounting bracket 42 shown in fig. 27. As shown in fig. 29 and 30, a first harness plug 69 is fixedly disposed outside the harness 64 for filling a space between the harness 64 and the first fixing buckle 681, limiting the movement of the harness 64, and the harness 64 can also function to fix the harness 64 by passing through the first harness plug 69. The fixed harness seat 68 includes a first fixing catch 681 disposed on the lens mounting bracket 42, and the first fixing catch 681 catches the first harness plug 69 to fix the first harness plug 69 with respect to the lens mounting bracket 42. Thus, the wiring harness 64 is easily put in via the first fixing catch 681, and the wiring harness 64 is fixed with the first harness plug 69 on the mount back 423 of the lens mount 42.

In other embodiments, the first fixing catch 681 for fixing the harness seat 68 and the harness 64 are adhered together with glue. Thus, a harness fixing point is provided near the outer first fixing buckle 681, and the harness fixing point is set as a glue point to fix the harness 64 by applying glue. The purpose of setting the harness attachment point is to ensure as little movement of the harness 64 within the lens mounting bracket 42 as possible. The wire harness 64 is wound on the wire winding assembly 63 in the manner shown in fig. 30 after passing through the fixing point with the lens mounting bracket 42, and the wire incoming direction of the wire harness 64 is along the tangential direction of the wire winding assembly 63, so that the twisting motion of the wire harness 64 is converted into the up-and-down motion along the tangential direction of the wire winding assembly 63. The two embodiments described above fix the wiring harness 64, and the fixing scheme of the wiring harness 64 can be selected autonomously according to the actual application. Wherein, the glue can be adhesive tape or glue. Thus, when the adhesive is an adhesive tape, the adhesive tape can be used to position the wire harness 64 at a position corresponding to the first fixing buckle 681, which is convenient to install.

Continuing with fig. 28 and 30, the fixed harness seat 68 is located behind and below the position-limiting harness seat 65, the winding assembly 63 is located below the fixed harness seat 68, and the harness 64 extends from the position-limiting harness seat 65, obliquely downward to the fixed harness seat 68, and further downward to the winding assembly 63. In this way, the stability of the wire harness 64 is improved by fixing the harness seat 68 after the wiring manner of the wire harness 64 is restricted on the basis of the first limit harness seat 66 and the second limit harness seat 67. Further, the fixed harness seat 68 includes a harness plug, and the internal structure of the harness plug is stable, so that the interference condition generated in the movement process of the harness 64 driven by the first lens 132 is avoided. The winding assembly 63 includes a winding post 631 protruding from the main housing 18, the winding post 631 is spaced apart from the pitching rotating motor 41, the winding post 631 is disposed in a staggered manner with respect to the pitching rotating motor 41 and the first lens 132 and is located below the pitching rotating motor 41 and the first lens 132, the wiring harness 64 includes a winding section 6422 wound around the winding post 631, and the winding section 6422 extends spirally from one end to the other end thereof. Thus, by designing the routing mode of the wire harness 64, the movement mode of the wire harness 64 is changed freely to be spiral movement around the winding post 631, the torsion of the wire harness 64 is limited, and the service life of the wire harness 64 is prolonged on the premise that the first lens 132 can move normally.

In the embodiment shown in fig. 28 and 30, the winding post 631 extends in the second direction Q perpendicular to the first direction W to the rear side of the main body case 18, and both ends of the winding section 6422 are located on the side of the winding post 631 in the first direction W away from the pitch rotation motor 41. The second direction Q may be the first direction W and may be a front-rear direction. So, post 631 occupies the space in second direction Q, conveniently sets up post 631. Wherein, one end of the winding post 631 is connected to the rear side of the main body case 18. Thus, the axial direction of the winding post 631 is perpendicular to the main housing 18, and the space occupied by the main housing 18 is reduced.

As shown in fig. 30, a wire harness fixing structure 6311 is provided on the periphery of the winding post 631, and one end of the winding section 6422 near the main board is fixed to the wire harness fixing structure 6311 and fixed to the winding post 631 through the wire harness fixing structure 6311. In this manner, the wire harness 64 is fixed by the wire harness fixing structure 6311 of the winding post 631. Further, a wire harness fixing structure 6311 is also provided at the end of the wire winding assembly 63. The fixing scheme of the wire harness fixing structure 6311 is the same as that of the wire harness base 68, and a corresponding fixing scheme is adopted according to actual requirements.

In the embodiment shown in fig. 31, the winding post 631 extends in the first direction W from the main housing 18, and both ends of the winding section 6422 are located on the side of the winding post 631 away from the pitch rotation motor 41 in the second direction Q. In this way, the winding section 6422 of the winding post 631 can avoid the pitching rotation motor 41, and reduce interference between the wire harness 64 and the pitching rotation motor 41. Wherein, both ends of the winding post 631 are connected to the rear side of the main housing 18. As such, the axial direction of the bobbin 631 is parallel to the main body case 18, reducing the space occupied by the camera 10 in the second direction Q, and the stability of the bobbin 631 being coupled to the main body case 18 may be enhanced. The axial direction of the winding post 631 is parallel to the direction of the first lens 132, the winding post 631 is fixed to the wire harness fixing structure 6311 by a screw, and the wire harness 64 is wound on the winding post 631 after passing through the wire harness fixing structure 6311. Unlike the winding post 631 shown in fig. 30, the directional winding post 631 can save space but the installation of the directional winding post 631 is complicated, and the arrangement scheme of the winding post 631 can be selected according to actual requirements.

Fig. 32 is a schematic diagram illustrating a change in relative positions of the wiring harness 64 and the winding post 631 when the lens tail 1322 of fig. 28 moves from the highest point to the lowest point. As shown in fig. 26, 28 and 32, when the first lens 132 moves in the third direction UR, the wire harness 64 may move up and down along the axial direction of the winding post 631. Fig. 32 shows the change of the relative position between the wire harness 64 and the winding post 631 when the tail 1322 of the first lens 132 moves from the highest point to the lowest point, and when the tail 1322 of the first lens 132 is located at the highest point, a margin is left between the wire harness 64 and the winding post 631 to avoid pulling the wire harness 64. The third direction UR is perpendicular to the first direction W and the second direction Q, and the third direction UR may be a vertical direction.

Fig. 33 is another perspective view of the camera 10 of fig. 1, showing a fill light assembly. As shown in fig. 33, the front cover 16 further includes a third through hole 163. The camera 10 further includes a fill-in light assembly 71 disposed in the third through hole 163, and the third through hole 163 is configured to avoid the fill-in light assembly 71, so that light of the fill-in light assembly 71 can irradiate the monitored area. As such, the fill light assembly 71 is configured to emit light to illuminate the monitored area through the front cover 16.

The light supplement lamp assembly 71 is disposed between the front cover 16 and the main housing 18, the light supplement lamp assembly 71 and the second lens assembly 14 are located on the same side of the reflector 151 in the vertical direction, and the horizontal rotation motor is located behind the light supplement lamp assembly 71 in the main housing 18. Thus, the light supplement lamp assembly 71 is disposed on the front cover 16, the horizontal rotation motor is disposed behind the light supplement lamp assembly 71, and the light supplement lamp assembly 71 is disposed in the third through hole 163, so that the occupied size is small, and the structure of the camera 10 is more compact.

The first through hole 161 is located above the second through hole 162 and the third through hole 163, the second through hole 162 and the third through hole 163 are provided adjacent to each other, and the area of the first through hole 161 is larger than the area of the second through hole 162. Compared with the prior art in which the light supplement lamp assembly 71 is separately arranged for each lens, the size is large, the camera 10 in the embodiment of the application has the first lens assembly 13 and the second lens assembly 14 to realize monitoring and linkage snapshot, wherein the reflector 151 is used for imaging of the first lens assembly 13, the requirement at night can be met for ensuring the light supplement of the first lens assembly 13 and the second lens assembly 14, and meanwhile, the light supplement does not interfere with each other for meeting the requirement of the size of the device as small as possible. Meanwhile, the first lens assembly 13 can cover a large field angle through P, so that linked capture is realized, and meanwhile, the installation of the first lens assembly 13 and the second lens assembly 14 and the coverage of the field angle are realized. In addition, the first through hole 161 is located above the second through hole 162 and the third through hole 163, and the second through hole 162 and the third through hole 163 are disposed adjacent to each other, so that light can be supplied to the second through hole 162 and the first through hole 161 at the same time, and thus, the first lens assembly 13 and the second lens assembly 14 use the same light compensation plate, thereby achieving the scheme of minimum device size and optimal light compensation.

The second through hole 162 and the third through hole 163 are horizontally arranged. Thus, the light from the third through hole 163 is more easily irradiated to the second through hole 162 to supplement the light to the second lens assembly 14, and is simultaneously irradiated to the first through hole 161 to supplement the light to the first lens assembly 13.

Continuing with fig. 33, the second through hole 162 includes a first side 1621 and a second side 1622 opposite in the first direction W, the third through hole 163 includes a third side 1631 and a fourth side 1632 opposite in the first direction W, the second side 1622 and the third side 1631 are adjacent, and a horizontal distance between the first side 1621 and the fourth side 1632 is smaller than or equal to a horizontal dimension of the first through hole 161.

The vertical dimension of the first through hole 161 is larger than the vertical dimension of the second through hole 162. The vertical dimension of the first through hole 161 is larger than the vertical dimension of the third through hole 163. Therefore, under the condition that the horizontal movement and the vertical movement are highly integrated on the main machine shell 18, and the integral form of the camera 10 is reduced, and the light supplementing scheme is added, the whole structure is very compact, the number of parts is small, and the cost is low.

As shown in fig. 47 and 48, after the light beam is vertically incident on the first window glass 1613 of the camera, the light beam passes through the reflector 151 and the first lens 132, and is zero coordinates of the pan/tilt head when the light beam can irradiate the center of an image sensor (CMOS for short). I.e. P =0, t =0. The optical axis of the first lens 132 is rotated downward in the positive direction, and the mirror 151 is rotated rightward in the positive direction in plan view. When movement is required, the image horizontal rotation angle is 2 times of the real rotation angle of the reflecting mirror 151, and the rotation range is half of the horizontal field angle. The vertical rotation angle of the image is the rotation angle of the rotating mechanism, and the range is the vertical field angle of the panoramic road. In the rotating process, the centers of the detail road images are all in the field of view of the panoramic road.

As such, light incidence may be more facilitated by the first region 1513.

Fig. 49 is an enlarged schematic view of the second lens assembly shown in fig. 1 for taking a picture.

As shown in fig. 49, the camera 10 is configured to determine the pan angle and the tilt angle in response to detection of world coordinates of at least one photographic subject so that the photographic subject is in the center area of the image photographed by the camera 10 at the pan angle and the tilt angle. Thus, compared with the spherical camera 10 of the PT camera 10 in the related art, in the rotation process, because the volume of the spherical camera 10 is large, the rotation speed is relatively slow, which results in missing a captured target, and also causes the whole camera 10 to shake due to rotation, which results in image blur, in the embodiment of the present application, the mirror assembly and the first lens assembly 13, which are located on the optical path where the light of the monitored area enters the first lens assembly 13, are respectively smaller than the whole camera 10, and the whole camera 10 shakes less due to rotation, which results in higher image definition.

Continuing with FIG. 49, a rectangular frame is drawn in the video image on the display by an input device such as a mouse as an interest frame, thereby determining center coordinates (Xr, yr) of the drawn frame as interest target coordinates; and determining the size of the interest box as one of Wr and Hr which is longer. Assuming that the current focal length is f and the vertical resolution is H, the target focal length f of the enlarged interest box can be estimated _r Comprises the following steps:

the pan/tilt head of the device will then drive the camera 10 in rotation until the centre of the image coincides with the centre of interest. While the camera 10 is zoomed until the diagonal field angle coincides with the field angle of interest. If the frame is not pulled out by the length of the frame when the frame is drawn, i.e., the interest frame is a point and Wr is 0, the pan/tilt head rotates, but the camera 10 does not zoom. If Wr>0, but f _r And if the focal length is less than the maximum magnification of the equipment, the magnification is maximized.

Fig. 50 is a schematic diagram showing the horizontal and pitch angles of the camera 10 shown in fig. 1.

As shown in fig. 50, the camera 10 is configured such that: converting world coordinates into spherical coordinates; and determining a horizontal rotation angle P and a pitching rotation angle T according to the spherical coordinates. The horizontal rotation angle is an absolute value of an inverse tangent function of a horizontal-vertical ratio in a horizontal coordinate in world coordinates. The pitch rotation angle is the absolute value of the arcsine function of the ordinate in world coordinates. Where P (pan, rotation angle in horizontal direction). T (tile, angle of rotation in the vertical direction). The detailed calculation process of the horizontal rotation angle & lt P & gt and the pitching rotation angle & lt T & gt is as follows. Continuing with FIG. 50, the camera 10 parameters include internal participation and external parameters. The references include distortion parameters and an internal reference matrix, representing the properties of the camera 10 itself, which are not altered externally. Only the zoom camera 10 changes when it is zoomed.

Wherein M is _int For internal reference, f is the current focal length in millimeters, dx and dy are the CMOS pixel width and height in millimeters, and w and h are the image horizontal resolution in pixels. And, the external reference is a matrix and the internal includes the displacement [ T]And attitude [ R]I.e. the pose in normal times.

Assuming that the displacement T is 0 and the rotation sequence is X, Y, Z, the extrinsic matrix M _ext Comprises the following steps:

the external parameters of the camera 10 are generated as follows: in the modeling, a cartesian coordinate system is used as a default, and the CMOS center of the camera 10 is set to 0 point. When there are only two dimensions x, y, the image is considered to be in the plane Z = 1. The coordinate system used by the ball machine is the position of 0 in the Y-axis negative direction, so the ball machine needs to be rotated to the Y-axis negative direction during initialization.

To this end, the initialized external reference matrix is:

after initialization, according to the PT value of the camera, respectively rotating around the X axis and the Z axis to generate a group of external parameter matrixes M _ext Comprises the following steps:

the above coordinates are converted as follows: after the internal parameters, the distortion parameters and the external parameters exist, the coordinate conversion can be carried out. The PT coordinate flow of the image coordinate ball rotating machine is as follows:

PT to 3D (world coordinates):

3D-to-2D:

P _uv ＝M _int ·M _ext ·P _3Dn

2D to 3D:

3D-PT coordinate transformation:

in this manner, accurate interconversion of the photographic image object of the second lens assembly 14 to the center of the first lens assembly 13 can be achieved. Therefore, the first lens assembly 13 can move in the visual field of the second lens assembly 14 through the movement of the reflecting mirror 151 and the camera 10 in the equipment, so that quick snapshot is realized, the shake generated in the moving process is extremely small, and the definition of a snapshot image is ensured.

The front cover 16 covers the front side of the main housing 18 and includes a rectangular first through hole 161, wherein a first edge of the first through hole 161 extending in the longitudinal direction is close to the first housing sidewall 183 relative to the second housing sidewall 184 and is spaced from the first housing sidewall 183 by a first distance, and a second edge of the first through hole 161 extending in the longitudinal direction is spaced from the second housing sidewall 184 by a second distance, wherein the first distance is smaller than the second distance; the first lens assembly 13 is disposed in the main housing 18 near the second housing sidewall 184. Wherein the camera 10 is configured to: when the mirror 151 rotates from the first horizontal boundary position to the second horizontal boundary position and the first lens 132 is kept still all the time, the locus 22 of the horizontal intersection point of the optical axis of the first lens 132 and the mirror 151 deviates from the center 1512 of the reflecting surface. When the first lens 132 rotates from the first tilt boundary position 133 to the second tilt boundary position 134 and the mirror 151 is kept still all the time, the locus of the tilt intersection point of the optical axis of the first lens 132 and the mirror 151 deviates from the center of the reflecting surface. In this way, the track 22 of the horizontal intersection point of the optical axis of the first lens 132 and the reflecting mirror 151 is not collinear with the center 1512 of the reflecting surface of the reflecting mirror 151, and horizontal rotation of the reflecting mirror 151 and pitching rotation of the first lens 132 are realized to complete image capturing of the monitored area, and also, linkage of the first lens assembly 13 and the second lens assembly 14 and miniaturization of the camera are realized. In the embodiment of the present application, the mirror 151 is horizontally rotated in a small range and rapidly rotated. Wherein, the rotating shaft of the horizontal rotating motor extends vertically, and the rotating shaft of the pitching rotating motor 41 extends horizontally; the central axis of the rotation shaft of the horizontal rotation motor is not coplanar with the central axis of the rotation shaft of the pitch rotation motor 41.

Fig. 52 is a schematic diagram illustrating image zones of the second lens assembly 14 shown in fig. 51.

As shown in fig. 51 and 52, the second lens assembly 14 includes a second lens 142, and the second lens 142 includes a second lens element (not shown) and a second image sensor (not shown). Wherein the camera 10 is configured to: in response to an object photographed by the second lens 142, a first control instruction for adjusting a horizontal angle of the mirror 151 and/or a second control instruction for adjusting a pitch angle of the first lens 132 are determined based on a mapping matrix between the second lens 142 and the first lens 132. Accordingly, in response to the first control instruction, the horizontal rotation structure performs a horizontal angle to cause the reflecting mirror 151 to adjust the horizontal angle; and/or, in response to the second control instruction, the tilt driving structure executes the tilt angle to drive the first lens 132 to adjust the tilt angle, so that when the camera 10 is located at the P coordinate and the T coordinate, the object is located at the preset position of the image captured by the first lens 132. In this way, the first lens 132 and the second lens 142 are linked to adjust the horizontal angle and the tilt angle of the camera 10.

Wherein, the second lens assembly 14 is located below the reflector 151, and the field of view range of the second lens assembly 14 covers the field of view range of the first lens assembly 13; the camera 10 is configured to: the horizontal angle of the reflecting mirror 151 is the value of the inverse tangent function of the P coordinate; the pitch angle is the value of the inverse tangent function of the T coordinate. Thus, the horizontal angle and the pitch angle can be obtained and calculated in real time.

As shown in fig. 51, the linkage between the second lens assembly 14 and the first lens assembly 13 includes two types, i.e., forward and reverse. Forward linkage: at any point M in the image of the second lens assembly 14, a set of PT values can be found for the first lens assembly 13, where PT values refer to the sum of P and T values. When the first lens assembly 13 moves to this PT coordinate, the image centre N coincides with point M; reverse linkage: the center point N of the first lens assembly 13 can find the point M in the image of the second lens assembly 14 coincident with it at any PT, which is also the coordinate of P and T together.

As shown in fig. 52, the camera 10 is configured to: an image containing the subject is acquired using the second lens assembly 14. The position of the object in the image is determined. In response to the mapping matrix between the second lens assembly 14 and the first lens assembly 13, the P coordinate for driving the reflecting mirror 151 and the T coordinate for driving the first lens 132 are determined according to the positions so that the subject is defined to be in a preset area where the first lens assembly 13 captures an image when the camera 10 is in the P coordinate and the T coordinate. The horizontal angle of the reflecting mirror 151 is adjusted according to the P coordinate. And adjusting the pitch angle of the first lens 132 according to the T coordinate. Further, the second lens assembly 14 is located below the reflecting mirror 151, and the field range of the second lens assembly 14 covers the field range of the first lens assembly 13. The camera 10 is configured to respond to a mapping matrix corresponding to a preset area; the preset area is one of a plurality of transverse areas, the plurality of transverse areas are obtained by transversely dividing the shot image of the first lens assembly 13 according to the parallax size of the second lens assembly 14 and the first lens assembly 13, the larger the parallax of the second lens assembly 14 and the first lens assembly 13 is, the smaller the corresponding preset area is, and the mapping matrix is determined according to the position of at least 4 points on the area boundary line in each transverse area in the plurality of transverse areas and the position of the alignment point when the second lens 142 aligns at least 4 points; at least 4 points are respectively at least two rows, and two points are taken in each row; and determining the P coordinate and the T coordinate according to the corresponding mapping matrix and the position.

As shown in FIG. 52, the PT of the camera 10 is a virtual plane for the first lens assembly 13= (0,0), the optical center is perpendicular to the plane, the plane distance from the camera 10 is L, then for each PT value, the coordinate of the image center aligned to the virtual plane is (X) _G ，Y _G )，X _G ＝TanP，Y _G = TanT. The monitoring range of the camera 10 is mostly the ground, so it is generally installed at a depression angle. Since the second lens assembly 14 is directly below the reflecting mirror 151, it can be considered that the second lens assembly 14 and the first lens assembly 13 are not deviated by displacement in the horizontal direction. While deviations in the vertical direction cannot be neglected. The closer the object distance, the greater the parallax produced by the two cameras 10. To solve this problem, a strategy of layering panoramic images is adopted: dividing the panoramic image into n preset areas from top to bottom, wherein the longitudinal coordinates of the non-line of the first line are Y0 and Yn respectively, and adding division lines Y1, Y2, … and Yn-1. Each dividing line divides the lower one of the preset regions into half.

In the calibration process, any point is taken on the left half and the right half on each horizontal line respectively, so that 2n +2 points are generated together, and the points are used as calibration points. Let the first lens assembly 13 adjust the pan-tilt coordinate PT so that the image centers of the cameras 10 are respectively aligned with 2n +2 points in the second lens assembly 14. As shown in fig. 52, the number of the preset regions may be 4. Four point coordinates such as point a (XRA, YRA) on each predetermined area side in the image plane R of the second lens assembly 14 and four point virtual coordinates such as point a (XGA, YGA) on the corresponding virtual plane G may form a mapping relationship of table 1.

Table 1 shows that four groups of point pairs can form a mapping relation

Point location	Coordinates of pixels in an image	Coordinates in a virtual plane
			A	(X _RA ,Y _RA )	(X _GA ,Y _GA )
B	(X _RB ,Y _RB )	(X _GB ,Y _GB )
			C	(X _RC ,Y _RC )	(X _GC ,Y _GC )
D	(X _RD ,Y _RD )	(X _GD ,Y _GD )

There is a relationship G = H × R, H being a homography matrix of R to G of the camera 10. The homography matrix size is 3 rows and 3 columns, then the relationship is:

the parameters in the homography matrix H can be solved by substituting the corresponding points of the four groups of coordinate pairs (as shown in Table 1) into the relational expression. That is, a mapping relationship of the second lens assembly 14 to the virtual plane in the preset area a is obtained. The predetermined regions 1 to n correspond to the matrices H1 to Hn.

The homography matrix is a 3 × 3 matrix with 9 parameters, and the parameters in the specific homography matrix H are as follows:

however, the coordinates used in the embodiment of the present application are homogeneous coordinates, and have scale invariance, and only 8 parameters need to be solved in practice. For example, there is a set of point pairs (u) ₁ ，v ₁ ) And (u) ₂ ，v ₂ ) Then there is a homogeneous relationship:

and

first, the relationship is transformed according to the list homographies:

extracting h from the homography matrix ₃₃ As a factor, and is introduced into the homogeneous matrix of points,

the relationship of the two coordinates is expanded as follows:

will be the above formula h ₃₃ The variables of (2) are reduced and simplified to obtain:

will (u) ₁ ，v ₁ ) Substituted into (u) ₂ ，v ₂ ) To obtain:

one set of coordinate pairs may list 2 equations and four sets may list 8 equations. The 8 unknowns can be found. In practical use, firstly, the area and the corresponding matrix H are found according to the coordinate Y of the second lens assembly 14R. Then, the coordinates of the point in the camera are substituted into G = H × R, and the virtual coordinates (X) are obtained _G ，Y _G ) And then ≈ P = ATan (X) can be found _G ) And ≈ T = ATan (Y) _G ). Thus, the first lens assembly 13 completes the snapshot through the vertical rotation and the horizontal galvanometer rotation.

For example: in the second lens assembly 14, the resolution is 1920 × 1080, with one point (x) within the second partition of the image _r ，y _r ) I.e. H = H2. The virtual coordinate x is obtained by the following formula _g And y _g ：
