Detailed Description
The following describes the optical imaging device carrying bracket, the panoramic scanning device and the panoramic scanning monitoring system in further detail with reference to the accompanying drawings and the specific embodiments.
Referring to fig. 1, the present invention provides an optical imaging device bearing bracket 1330, which includes a support plate 1331, a first galvanometer unit 1333 and a second galvanometer unit 1337, wherein the first galvanometer unit 1333 and the second galvanometer unit 1337 are respectively disposed on two opposite surfaces of the support plate 1331.
Specifically, the support plate 1331 has a first surface and a second surface opposite to each other, and the first galvanometer unit 1333 may be disposed on the first surface of the support plate 1331; the second galvanometer unit 1337 may be disposed at the second surface of the support plate 1331. The support plate 1331 is used for supporting the first galvanometer unit 1333 and the second galvanometer unit 1337, and the material of the support plate 1331 may be metal or polymer material, so long as the support plate 1331 has a certain hardness, and can support the first galvanometer unit 1333 and the second galvanometer unit 1337. The support plate 1331 is rotatably provided, and further, the support plate 1331 is rotatable about a rotation axis. Specifically, the support plate 1331 may have a symmetrical structure, and has a symmetry axis, and the support plate 1331 may rotate about the symmetry axis as a rotation axis. The first and second galvanometer units 1333 and 1337 are disposed on the support plate 1331, so that the first and second galvanometer units 1333 and 1337 can rotate in synchronization with the support plate 1331.
Referring to fig. 2 and 3, the first galvanometer unit 1333 includes a first galvanometer lens 1334 and a first galvanometer motor 1335, the first galvanometer lens 1334 has a first rotation axis, the first galvanometer lens 1334 rotates around the first rotation axis, and the first rotation axis can be coaxially disposed with a driving shaft of the first galvanometer motor 1335, so as to rotate around the first rotation axis under the driving of the first galvanometer motor 1335. Similarly, the second galvanometer unit 1337 includes a second galvanometer lens 1338 and a second galvanometer motor 1339, the second galvanometer lens 1338 has a second rotation axis, the second galvanometer lens 1338 rotates around the second rotation axis, and the second rotation axis can be coaxially arranged with the driving shaft of the first galvanometer motor 1335, so that the second galvanometer lens 1338 can rotate around the second rotation axis under the driving of the second galvanometer motor 1339. Further, the first rotation axis is parallel to the second rotation axis, and further, the first rotation axis and the second rotation axis may be parallel to the symmetry axis of the support plate 1331, and preferably, the first rotation axis and the second rotation axis are symmetrically disposed with respect to the symmetry axis.
In a specific embodiment, in an initial state, i.e. the first vibrating mirror 1334 and the second vibrating mirror 1338 are not subjected to vibration compensation, the first vibrating mirror 1334 and the second vibrating mirror 1338 are located at an initial position and are in a relatively static state, and the surface of the first vibrating mirror 1334 can form an included angle of 45 degrees with the first surface of the supporting plate 1331; similarly, the surface of the second galvanometer lens 1338 may form an angle of 45 degrees with the second surface, so that the light incident perpendicular to the first surface and the second surface propagates in a direction parallel to the first surface and the second surface after being reflected by the first galvanometer lens 1334 and the second galvanometer lens 1338. In addition, the first mirror 1334 may be perpendicular to the second mirror 1338, so that light incident from the same direction along a direction perpendicular to the support plate 1331 propagates in the opposite direction along a surface parallel to the support plate 1331 after being reflected by the first mirror 1334 and the second mirror 1338. It will be appreciated that the selection of the included angle is merely a specific embodiment, and may also be selected according to the setting of the subsequent imaging module.
Further, the first and second galvanometer units 1333 and 1337 may be disposed in opposite directions. Specifically, when the first mirror unit 1333 is set up in the forward direction, then the second mirror unit 1337 is set up in the reverse direction, thereby make the first mirror lens 1334 and the second mirror lens 1338 reverse the setting, can reduce the space that first mirror unit 1333 and second mirror unit 1337 occupy, in order to make things convenient for the setting of follow-up imaging module under the fixed circumstances of backup pad 1331 area, in order to reduce the whole volume that occupies of optical imaging device bearing support 1330, be favorable to the design of the integrated and light path of follow-up other components and parts.
Further, the support plate 1331 is formed with a first through hole 1303 and a second through hole 1304, the first through hole 1303 and the second through hole 1304 are respectively provided corresponding to the first vibrating mirror 1334 and the second vibrating mirror 1338, and the light incident from the first through hole 1303 is incident on the surface of the first vibrating mirror 1334 and the light incident from the second through hole 1304 is incident on the surface of the second vibrating mirror 1338. Specifically, the surface of the first vibrating mirror 1334 facing the support plate 1331 is exposed from the first through hole 1303, and the surface of the second vibrating mirror 1338 facing the support plate 1331 is exposed from the second through hole 1304 to reflect light incident from the first through hole 1303 or the second through hole 1304. Therefore, the incident light can be acquired more conveniently, and the setting of a subsequent imaging unit is more facilitated. Meanwhile, by providing the first through hole 1303 and the second through hole 1304, the first galvanometer lens 1334 and the second galvanometer lens 1338 can reflect the light incident from the same viewing angle, so as to facilitate the subsequent image acquisition and analysis of different types of images in the viewing angle.
It should be understood that the arrangement of the first through hole 1303 and the second through hole 1304 is merely a specific embodiment, and when the first galvanometer unit 1333 and the second galvanometer unit 1334 are located on different surfaces of the support plate 1331, only one through hole may be provided, so that light incident from the same direction can be respectively incident on the first galvanometer lens 1334 and the second galvanometer lens 1338. Further, by providing the first through hole 1303 and the second through hole 1304, the adjustment of the first and second galvanometer lenses 1334 and 1338 can be more flexible, so as to be suitable for obtaining the light rays incident in the same direction or different directions, and the occupation of the space can be reduced.
Further, the optical imaging device support 1330 includes a first imaging module support platform 1301 and a second imaging module support platform 1302, which are respectively configured to set up a first imaging module and a second imaging module, so as to obtain incident light reflected by the first galvanometer lens 1334 and the second galvanometer lens 1338, respectively. The first imaging module carrying platform 1301 may be disposed on the first surface. Specifically, the imaging module may be disposed on the optical path of the light reflected from the first galvanometer lens 1334, so that the imaging module disposed in the first imaging module carrying platform 1301 can obtain the light reflected from the first galvanometer lens 1334; that is, the light incident on the first galvanometer lens 1334 can enter the first imaging module carrying platform 1301 after being reflected by the first galvanometer lens 1334; similarly, the second imaging module support platform 1302 may be disposed on a second surface. Specifically, the imaging module disposed in the second imaging module carrying platform 1302 may be disposed on an optical path of the light reflected by the second galvanometer lens 1338, so that the imaging module disposed in the second imaging module carrying platform 1302 may obtain the light reflected by the second galvanometer lens 1338, that is, the light incident on the second galvanometer lens 1338 is reflected and then incident on the second imaging module carrying platform 1302.
Further, the first imaging module carrying platform 1301 is disposed near the first galvanometer lens 1334, and the second imaging module carrying platform 1302 is disposed near the second galvanometer lens 1338, so as to receive the incident light of a large angle as much as possible. The setting position of the first imaging module carrying platform 1301 is symmetrical to the setting position of the second galvanometer motor 1339 with respect to the support plate 1331, and similarly, the setting position of the second imaging module carrying platform 1302 is symmetrical to the setting position of the first galvanometer motor 1335 with respect to the support plate 1331, so that the required area of the support plate 1331 can be reduced, and the integration level of the whole device can be improved.
It should be understood that the first and second galvanometer units 1333 and 1337 may be disposed on the same surface of the supporting plate 1331, so long as the first and second galvanometer units 1333 and 1337 are disposed in parallel; meanwhile, by adjusting the initial positions of the first vibrating mirror 1334 and the second vibrating mirror 1338, the incident light in the same direction can be reflected by the first vibrating mirror unit 1333 and the second vibrating mirror unit 1337 and then can be respectively incident on the first imaging module bearing platform 1301 and the second imaging module bearing platform 1302, and the first vibrating mirror unit 1333 and the second vibrating mirror unit 1337 can simultaneously play a role in compensation. In addition, when the first and second galvanometer units 1333 and 1334 are positioned on the same surface of the support plate 1331, the first and second through holes 1303 and 1304 may not be provided.
Further, the support plate 1331 may be rotated by an external motor (not shown) about a symmetry axis of the support plate 1331, so as to drive the optical imaging device support bracket 1330 to rotate. Meanwhile, the first and second galvanometer motors 1335 and 1339 drive the first and second galvanometer lenses 1334 and 1338 to rotate around their own rotation axes in opposite directions with respect to the rotation direction of the support plate 1331. Further, the angular velocity of the first and second galvanometer lenses 1334 and 1338 rotating around their own rotation axes may be half of the rotational angular velocity of the support plate 1331, so as to compensate the images entering the imaging modules disposed in the first and second imaging module support platforms 1301 and 1302.
When the optical imaging device bearing support 1330 is used, an imaging module can be arranged in the first imaging module bearing platform 1301 to receive the light reflected by the first galvanometer lens 1334, and meanwhile, the rotation of the first galvanometer lens 1334 is used for compensating the image acquired by the imaging module under the driving of the first galvanometer motor 1335; similarly, the second imaging module carrier 1302 may also be disposed in the second imaging module carrier 1302 to receive the light reflected by the second galvanometer lens 1338, and compensate the image with the second galvanometer lens 1338. In addition, two imaging modules may be disposed in the first imaging module carrying platform 1301 and the second imaging module carrying platform 1302 at the same time, and the two imaging modules may be different types of imaging modules, so as to obtain images of different types and different angles, thereby being beneficial to the synthesis of two subsequent different images.
Further, the optical imaging device support 1330 may rotate under the driving of a rotating motor (not shown), the first and second galvanometer lenses 1334 and 1338 rotate synchronously with the support plate 1331, and the first and second galvanometer lenses 1334 and 1338 rotate reversely relative to the rotation direction of the optical imaging device support 1330 under the driving of the respective first and second galvanometer driving motors 1335 and 1339. Specifically, the rotation axes of the first and second galvanometer lenses 1334 and 1338 are symmetrically distributed on two sides of the rotation axis of the bearing support 1330 of the optical imaging device, and the angular speed of the first and second galvanometer lenses 1334 and 1338 rotating around the rotation axis thereof may be equal to one half of the rotation angular speed of the bearing support 1330 of the optical imaging device, so as to reduce tailing, accurately compensate images formed in the rotation process, and improve imaging quality.
The optical imaging device bearing support 1330 is provided with the first vibrating mirror unit and the second vibrating mirror unit on two surfaces of the supporting plate respectively, so that imaging modules with different numbers and different types can be matched conveniently to be applied to different optical imaging scenes, different types of images can be obtained, and the images in each imaging module can be compensated to improve imaging quality, so that the optical imaging device bearing support 1330 has wide application space in the optical imaging field, especially the video monitoring and panoramic monitoring fields.

Specifically, the surface of the first vibrating mirror 1334 facing the support plate 1331 is exposed from the first through hole 1303, and the surface of the second vibrating mirror 1338 facing the support plate 1331 is exposed from the second through hole 1304 to reflect light incident from the first through hole 1303 or the second through hole 1304. Therefore, the incident light can be acquired more conveniently, and the setting of a subsequent imaging unit is more facilitated. Meanwhile, by providing the first through hole 1303 and the second through hole 1304, the first galvanometer lens 1334 and the second galvanometer lens 1338 can reflect the light incident from the same viewing angle, so as to facilitate the subsequent image acquisition and analysis of different types of images in the viewing angle. In this embodiment, the first through holes 1303 and the second through holes 1304 are staggered according to the first vibrating mirror 1334 and the second vibrating mirror 1338, so that the support plate 1331 has an "S" structure. It can be understood that the arrangement mode and the number of the through holes can be selected according to actual needs, so as to be suitable for different application environments.
The first imaging module 1332 and the second imaging module 1336 respectively include an area array image sensor, so that under the condition of high-speed rotation, enough static exposure time can be still ensured, clear images can be obtained, and high resolution precision is achieved.
Referring to fig. 9, the first galvanometer unit 1333 includes a first galvanometer lens 1334 and a first galvanometer motor 1335. The first galvanometer lens 1334 is disposed in front of the lens of the first imaging module 1332 to reflect light incident on the first galvanometer lens 1334 into the first imaging module 1332. Further, the first galvanometer mirror 1334 may vibrate within an angular range of at least plus or minus 10 degrees under the driving of the first galvanometer motor 1335. The first galvanometer motor 1335 is configured to drive the first galvanometer lens 1334 to reversely rotate and reset with respect to the rotation direction of the rotating platform 12. The first galvanometer lens 1334 is positioned at the initial position when the rotation compensation is not performed. The first galvanometer lens 1334 may be rotated forward and backward at a preset frequency within a range of plus or minus 10 degrees with respect to an initial position when the first galvanometer lens 1334 is not rotated by the driving of the first galvanometer motor 1335 and reset. Specifically, during shooting, the rotation direction of the first galvanometer lens 1334 is opposite to the rotation direction of the rotating platform 12, that is, the rotation direction of the first galvanometer lens 1334 is opposite to the rotation direction of the first imaging module 1332; when the rotary platform 12 rotates clockwise, the first galvanometer lens 1334 vibrates counterclockwise; otherwise, the first galvanometer lens 1334 is rotated clockwise. The positional relationship among the infrared window 1323, the first galvanometer lens 1334 and the first imaging module 1332 needs to satisfy that the infrared light coming from the infrared window 1323 is incident on the first galvanometer lens 1334, reflected by the first galvanometer lens 1334 and then incident on the lens of the first imaging module 1332, and imaged on the area array image sensor of the first imaging module 1332. Further, the angular velocity of the rotation of the first galvanometer lens 1334 may be one half of the rotational angular velocity of the rotating platform 12, and specifically, the angular velocity of the first galvanometer lens 1334 when rotating reversely relative to the first imaging module 1332 is one half of the rotational angular velocity of the first imaging module 1332. In this embodiment, the geometric center of the infrared window 1323, the geometric center of the first galvanometer lens 1334, and the geometric center of the first imaging module 1332 are located in the same horizontal plane.
Similarly, referring to fig. 10, the second galvanometer unit 1337 includes a second galvanometer lens 1338 and a second galvanometer motor 1339. The second galvanometer lens 1338 is driven by a second galvanometer motor 1339 to vibrate and reset within an angle range of plus or minus 10 degrees relative to the initial position, and the second galvanometer lens 1338 is arranged in front of the lens of the second imaging module 1336. Likewise, the second galvanometer mirror 1338 rotates in a direction opposite to the direction of rotation of the rotating platform 12. Further, the angular velocity of the second galvanometer lens 1338 rotating around the rotation axis thereof is half of the rotation angular velocity of the rotation platform, that is, the angular velocity of the second galvanometer lens 1338 rotating reversely relative to the second imaging module 1336 is half of the rotation angular velocity of the rotation platform, so as to accurately compensate the image formed in the second imaging module 1336 in the rotation process and improve the imaging quality. The positional relationship among the visible light window 1324, the second galvanometer lens 1338 and the second imaging module 1336 is to satisfy that the visible light coming from the visible light window 1324 is incident on the second galvanometer lens 1338, reflected by the second galvanometer lens 1338 and then incident on the lens of the second imaging module 1336, and imaged on the area array image sensor of the second imaging module 1336.
Further, in the present embodiment, in the initial position, the angle between the reflecting surface of the first galvanometer lens 1334 and the imaging surface of the infrared window 1323 and the first imaging module 1332 is 45 degrees; similarly, the reflecting surface of the second galvanometer mirror 1338 may also have an angle of 45 degrees with respect to the imaging surface of the visible light window 1324 and the second imaging module 1336; meanwhile, the first mirror 1334 and the second mirror 1338 are perpendicular to each other. The first imaging module 1332, the first galvanometer unit 1333, the second imaging module 1336 and the second galvanometer unit 1337 are matched with each other, and can be used for acquiring images in the same-direction viewing angle, and can also be used for acquiring images in viewing angles in different directions, such as opposite directions.
An image may be finally synthesized by the image obtained on the area array image sensor of the first imaging module 1332 and the image obtained on the area array image sensor of the second imaging module 1336 through an image processing system.
It is to be understood that the structure of the panorama scanning apparatus 10 of the present invention is not limited thereto, as long as the photographing unit 133 can rotate 360 degrees to realize panorama photographing. That is, the structure of the base 11 and the rotary platform 12 is not limited to the present embodiment, and may be other structures, for example, a single-layer rotary platform may be adopted, or the photographing unit 133 may be driven to rotate by a turntable, so long as the photographing unit 133 can rotate 360 degrees to achieve panoramic photographing.
Referring to fig. 11, in the panoramic scanning apparatus 10 of the present embodiment, the rotation speed of the photographing unit 133 in the panoramic scanning apparatus is generally controlled to meet the scanning requirement when performing panoramic scanning. If the angles of view of the lenses of the first imaging module 1332 and the second imaging module 1336 are θ, the separation number n is 360 °/θ, and the rotation speed of the photographing unit 133, including the first imaging module 1332 and the second imaging module 1336, needs to satisfy v+.f/n rpm, where f is the imaging frequency, that is, the number of frames photographed per second. In this embodiment, when f=50, that is, v.ltoreq.5θ/360 rotations/sec, v is an integer. For example, θ=18°, n=20, v+.2 rpm; θ=30°, n=12, v is less than or equal to 4 rotations/second; θ=60°, n=6, v+.8 rpm. The angle of view θ of the camera lens is different, and the rotation speed of the photographing unit 133 is also different. The photographing unit 133 performs photographing at the same time during rotation. Firstly, adjusting the pitch angle of a shooting unit 133 in the panoramic scanning apparatus by controlling the second motor 125 to determine the view finding range; then, the photographing unit 133 is controlled to make 360-degree rotation, and a panoramic image at a predetermined pitch angle is obtained.
In the photographing process, if the first and second galvanometer lenses 1334 and 1338 are not provided, the photographing effect must be greatly affected because the photographing unit 133 photographs while rotating, and the image may have a tailing phenomenon.
In the present invention, a first galvanometer lens 1334 and a second galvanometer lens 1338 are disposed in front of a first imaging module 1332 and a second imaging module 1336, respectively, and infrared rays emitted from a subject enter the first galvanometer lens 1334 through an infrared window 1323, enter a lens of the first imaging module 1332 through reflection of the first galvanometer lens 1334, enter the second galvanometer lens 1338 through reflection of the second galvanometer lens 1338, and enter a lens of the second imaging module 1336 through reflection of the second galvanometer lens 1338. The first and second galvanometer lenses 1334 and 1338 are rotated at a certain speed by the driving of the first motor 124, and simultaneously the first and second galvanometer lenses 1334 and 1338 are respectively controlled to vibrate at a certain angular speed by controlling the first and second galvanometer motors 1335 and 1339.
When taking a photograph, the first galvanometer lens 1334 can be controlled to reversely rotate at a certain angular velocity so as to compensate the movement of the image of the photographed object on the area array image sensor of the first imaging module 1332, so that the image of the photographed object on the area array image sensor of the first imaging module 1332 is static; and controlling the second galvanometer lens 1338 to reversely rotate at a certain angular velocity so as to compensate the movement of the image of the photographed object on the area array image sensor of the second imaging module 1336, so that the image of the photographed object on the area array image sensor of the second imaging module 1336 is static; that is, the inverse rotation motion of the first and second galvanometer lenses 1334 and 1338 compensates for the motion of the image of the photographed object on the area array image sensor, and makes the image of the photographed object on the area array image sensor stationary. Therefore, the imaging quality on the area array image sensor of the first imaging module 1332 and the second imaging module 1336 is better, and the tailing phenomenon does not occur. After the photograph is taken, the first and second galvanometer lenses 1334 and 1338 are respectively controlled to be rapidly rotated to their initial positions.
In the present embodiment, the angle of view θ of the lenses of the first and second imaging modules 1332 and 1336 is 18 degrees, and then the separation number n is 20, that is, the photographing unit 133 needs to take 20 photos to complete panoramic photographing. The rotation speed of the photographing unit 133 in the panorama scanning apparatus is set to 1 rpm by controlling the first motor 124, which corresponds to rotation at an angular speed of 360 degrees/sec. During the shooting process, the first and second galvanometer lenses 1334 and 1338 are respectively controlled to reversely rotate at an angular velocity of 180 degrees/second, that is, the rotation angular velocity of the first and second galvanometer lenses 1334 and 1338 is half of the rotation angular velocity of the first motor 124, so as to compensate the movement of the image of the shot object on the area array image sensor, and the image of the shot object on the area array image sensor is static. After the photographing is completed, the first and second galvanometer lenses 1334 and 1338 are respectively controlled to be rapidly rotated to their initial positions. Then, the image on the area array image sensor of the first imaging module 1332 and the image on the area array image sensor of the second imaging module 1336 are combined into an image through control software, and then the 20 images are combined into an image data through software, so that 360-degree panoramic shooting is realized.
It will be appreciated that by setting the optical positional relationship between the first and second galvanometer lenses 1334, 1338 and the first and second imaging modules 1332, 1336, for example, by making the first galvanometer lens 1334 parallel to the second galvanometer lens 1338, the first imaging module 1332 and the light imaging module 1336 may be used to acquire images within the relative viewing angles, that is, the imaging area of the first imaging module 1332 is opposite to the imaging area of the second imaging module 1336, so that the panoramic scanning apparatus 10 can acquire images within 360 degrees every 180 degrees of rotation. That is, when the panoramic scanner 10 rotates by 180 degrees, the panoramic image can be obtained after the image obtained by the first imaging module 1332 and the image obtained by the second imaging module 1336 are combined, so that the frequency of obtaining the panoramic image by the panoramic scanner 10 can be further increased, and the occurrence probability of monitoring blind areas is reduced.
In the panoramic scanning apparatus 10 of the present embodiment, since the first imaging module 1332 and the second imaging module 1336 are planar image sensors, the first galvanometer lens 1334 and the second galvanometer lens 1338 do not need to move and can be kept stationary, so that an image with high recognition degree can be obtained.
The panorama scanning device 10 has an infrared window, a visible light window, an infrared imaging module and a visible light imaging module, wherein the infrared imaging module and the visible light imaging module can rotate 360 degrees, so that the panorama scanning device can realize 24-hour all-weather 360-degree panorama shooting; further, the panoramic scanning device only adopts one infrared imaging module, so the cost is low. In addition, by providing the first galvanometer and the second galvanometer in the panoramic scanning device, the first galvanometer and the second galvanometer reversely rotate at a certain angular velocity in the shooting process of panoramic scanning, and the reverse rotation compensates the movement of the image of the shot object on the area array image sensor, so that the image of the shot object on the area array image sensor is static. Therefore, the panoramic scanning device has better image quality, no tailing phenomenon and greatly improved identification accuracy of the monitoring image.
In addition, in the staring process, as the infrared imaging module and the visible light imaging module are both plane array image sensors, the first vibrating mirror and the second vibrating mirror do not need to move and can obtain high-precision images after being kept stationary.
