Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an omnidirectional camera mounted on a vehicle.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally, various uses of in-vehicle cameras are known. For example, as shown in FIG. 3 (a), an auto cruise that attaches a vehicle exterior monitoring camera for recognizing the front of the vehicle to the ceiling above the inner mirror, recognizes a white line on the road, and performs inter-vehicle control and constant speed traveling control. It is considered to use it for control, or attach an infrared surveillance camera to a similar place, take a picture of the situation in front of the vehicle, and use it for the driver's visual assistance at night. Moreover, as shown in FIG.3 (b), it is also considered that a camera is built in an inner mirror and a surveillance camera outside a vehicle.
[0003]
However, in the case shown in FIGS. 3 (a) and 3 (b), in any case, a dedicated camera installed according to the monitoring direction is necessary. It is necessary to separately provide an in-vehicle surveillance camera with a view of the inside of the vehicle, which raises costs and secures a mounting space.
[0004]
On the other hand, as shown in FIG. 3C, it is conceivable that an in-vehicle monitoring camera using, for example, a fish-eye lens is provided on the ceiling above the inner mirror, and an occupant including a driver is detected and used for monitoring the inside of the vehicle. ing. In this case, by using a lens having a wide-angle field of view such as a fisheye lens, it is possible to bring both the inside and outside of the vehicle into view, but the inner mirror creates a blind spot. That is, if priority is given to the in-vehicle view, the inner mirror becomes a blind spot for the outside view, and conversely if the priority is given to the outside view, the inner mirror becomes a blind spot for the in-view field. As described above, in order to appropriately secure the view inside and outside the vehicle, it is necessary to prepare an in-vehicle monitoring camera and an out-of-vehicle monitoring camera.
[0005]
Therefore, an object of the present invention is to provide a camera that solves the above-described problems and can appropriately ensure both the in-vehicle visual field and the external visual field.
[0006]
[Means for Solving the Problems and Effects of the Invention]
The on-vehicle omnidirectional camera according to claim 1, which has been made to solve the above-described problems, is disposed between the mirror surface portion of the inner mirror in the vehicle and the windshield, and therefore, from an occupant, particularly a driver. It is very low even if it does not obstruct the field of view. In addition, since it has a field of view in all directions of 360 degrees at least in a substantially horizontal direction and in a predetermined portion below the substantially horizontal direction, a single camera can secure a field of view outside the vehicle and a field of view inside the vehicle. Since the optical system part where the light from the field of view first enters is arranged in the vicinity of the lowermost position of the inner mirror, the field of view inside the vehicle is not obstructed, or the degree is very low. Of course, from the viewpoint of the occupant, since the in-vehicle omnidirectional camera is located on the windshield side of the mirror surface, the field of view of the inner mirror is not disturbed.
The inner mirror stay is rotatable in the vertical direction, and the in-vehicle omnidirectional camera itself and the inner mirror stay or the camera case housing the in-vehicle omnidirectional camera and the inner mirror stay are connected by a link member, and at least the link member One end is rotatably attached so that the relative viewing direction does not change regardless of the vertical movement of the inner mirror stay. If the inner mirror stay can be rotated up and down, the degree of freedom in adjusting the angle of the inner mirror in the vertical direction is increased, but even in such a configuration, the relative orientation of the on-vehicle omnidirectional camera is maintained, The relative viewing direction can be prevented from changing.
[0007]
In particular, as shown in claim 2, if the inner mirror is arranged so that it does not enter the field of view of the on-vehicle omnidirectional camera, the inner mirror does not interfere with the field of view of the camera.
If the optical axis of the on-vehicle omnidirectional camera coincides with the vertical direction (the height direction of the vehicle), the outside field of view and the inside field of view are symmetrical with respect to a vertical line. That is, the maximum heights of the in-vehicle visual field and the external visual field are equal. However, the optical axis can be shifted from the vertical direction. For example, if the optical axis is tilted toward the mirror surface side or the windshield side of the inner mirror, the maximum height of the in-vehicle visual field or the external visual field can be made higher or lower than the other. For example, such a device is also effective when it is desired to relatively increase the outside field of view in the direction of the windshield.
[0008]
In addition, a lens, a convex mirror, or the like is conceivable as an optical system portion on which light from an omnidirectional visual field is first incident.
Further, the in-vehicle omnidirectional camera is arranged between the mirror surface portion of the inner mirror in the vehicle and the windshield. At that time, as shown in claim 3, if it is arranged near the center in the left-right direction of the inner mirror, Good. When the inner mirror is usually long in the left-right direction and the left-right inclination can be adjusted, the amount of movement of the left and right end portions is relatively large. Therefore, when the vehicle-mounted omnidirectional camera is arranged in such a large movement amount, a relatively large amount of separation from the inner mirror must be ensured in order to prevent interference. Then, in order to prevent the inner mirror from blocking the camera field of view as much as possible, the result is that the in-vehicle omnidirectional camera protrudes downward from the lowest position of the inner mirror, or the amount of protrusion is relatively large. . For this reason, as shown in claim 3, if the inner mirror is arranged near the center in the left-right direction, the amount of downward projection from the lowest position of the inner mirror of the in-vehicle omnidirectional camera is reduced, and the field of view of the occupant in front of the vehicle is reduced. The degree to which the in-vehicle omnidirectional camera blocks is relatively low.
[0009]
In addition, considering the case where the on-vehicle omnidirectional camera is attached to the inner mirror stay as described later, the left and right center of gravity of the camera is set to coincide with or near the center of gravity of the inner mirror stay. Alternatively, in the case of hinge coupling, there is also an advantage that the load on the coupling portion can be reduced.
[0010]
By the way, as an arrangement | positioning location of a vehicle-mounted omnidirectional camera, as shown, for example in Claim 4, arranging in the case fixed to the inner mirror stay can be considered .
[0013]
Further, since the vehicle-mounted omnidirectional camera is mounted on the vehicle, the vehicle-mounted omnidirectional camera may also vibrate due to vibration (from the vehicle body) from the vehicle, particularly during traveling. Therefore, as shown in claim 5 , it is preferable to provide a vibration suppressing member that suppresses vibration from the vehicle at the attachment portion of the vehicle-mounted omnidirectional camera itself or the case that houses the vehicle-mounted omnidirectional camera. In this way, it is possible to suppress the vibration of the vehicle from being transmitted to the in-vehicle omnidirectional camera, and to improve the accuracy of the imaging function of the in-vehicle omnidirectional camera. As a method for suppressing vibration, for example, a method that absorbs vibration by inserting an elastic member such as rubber in an attachment portion is simple. Of course, the configuration is complicated, but vibration may be actively suppressed.
[0014]
Note that the on-vehicle omnidirectional camera may have sensitivity in the visible light region or sensitivity in the infrared region, for example. However, when it is desired to exhibit a sufficient recognition function in a state where the visual field inside the vehicle or outside the vehicle is dark, it is preferable to employ one having sensitivity in the infrared region.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments to which the present invention is applied will be described below with reference to the drawings. Needless to say, the embodiments of the present invention are not limited to the following examples, and can take various forms as long as they belong to the technical scope of the present invention.
[0016]
[First embodiment]
FIG. 1 is a schematic explanatory diagram showing the mounting position and the like of the omnidirectional camera 1 in the first embodiment.
The omnidirectional camera 1 of the present embodiment is disposed in a camera case 3, and this camera case 3 is suspended and fixed inside the vehicle windshield 4. The camera case 3 may be directly fixed to the windshield 4 itself, or may be fixed so that the camera case 3 is hooked on a hook portion (button) fixed to the windshield 4. The camera case 3 is disposed between the inner mirror 2 and the windshield 4.
[0017]
Here, the inner mirror 2 is configured such that a substantially rectangular plate-like mirror surface portion 2a is housed in a mirror case portion 2b. And the mirror case coupling | bond part 5a provided in the one end side of the inner mirror stay 5 in the left-right direction center vicinity of the back side of the mirror case part 2b (because the mirror surface part 2a is arrange | positioned in the front side). It is attached so that it can rotate at a predetermined angle in any direction. Further, the other end side of the inner mirror stay 5 is attached to a glass fixing portion 7 that is suspended and fixed inside the windshield 4. The glass fixing part 7 may also be fixed directly to the surface of the windshield 4 or may be fixed to be hooked on a hook part fixed to the surface of the windshield 4. Such a configuration relating to the inner mirror 2 has been conventionally known, and an occupant (especially a driver) is suitable for checking the rear of the vehicle via the mirror surface portion 2a of the inner mirror 2 while sitting in the driver's seat. The mirror case 3 is adjusted by hand so that the vertical and horizontal angles are obtained.
[0018]
Further, the camera case 3 of the present embodiment is disposed near the center in the left-right direction of the inner mirror 2. Specifically, since the inner mirror stay 5 is attached near the center in the left-right direction of the mirror case portion 2 a, the vehicle-mounted omnidirectional camera case 3 is disposed so as to cover the inner mirror stay 5. Therefore, as shown in FIG. 1B, when viewed from the occupant, the inner mirror stay 5 cannot be seen and the camera case 3 can be seen behind the inner mirror 2.
[0019]
And the omnidirectional camera 1 was arrange | positioned in the bottom position vicinity of this camera case 3. FIG. Here, as shown in FIG. 1A, the omnidirectional camera 1 has a field of view in all directions of 360 degrees at least in a substantially horizontal direction and in a predetermined portion below the substantially horizontal direction. There are various types of cameras that can shoot 360-degree omnidirectional light. In this embodiment, the optical system part where light from the omnidirectional field of view first enters is the lens part 1a, and the lens part 1a. Are arranged so as to be at the lowermost end of the omnidirectional camera 1 and their optical axes are aligned with the vertical direction.
[0020]
Accordingly, when the omnidirectional camera 1 is viewed from the up and down direction, there is a field of view of 360 degrees, and when viewed from the left and right direction, as shown in FIG. There is a visual field of about several degrees above the direction and about 60 degrees below. Of course, the viewing angle when viewed from the left-right direction is an example, and it is conceivable that the viewing angle varies depending on the type of omnidirectional camera. However, here, it is assumed that the field of view is provided in all directions of 360 degrees at least in a substantially horizontal direction and in a predetermined portion below the substantially horizontal direction as described above. In addition, about the predetermined part below, it was described as about 60 degrees in the above example, but if it is more than that, the field of view will naturally widen, and there is no problem, and even if it is less than 60 degrees, the purpose of securing the inside / outside field of view It is considered that an appropriate viewing angle may be used depending on the situation. For example, even if it is about 30 degrees, there is no problem as long as the situation inside and outside the vehicle to be monitored can be grasped from the video taken at the viewing angle.
[0021]
Further, the lens portion 1a of the omnidirectional camera 1 is arranged so as to protrude slightly below the lowest position of the inner mirror 2 (that is, the lower end of the mirror case portion 2b). This protrusion amount is a minimum amount in consideration so that the inner mirror 2 does not enter the in-vehicle visual field. The omnidirectional camera 1 is attached to the camera case 3 via a damper 9. The damper 9 is an elastic member made of, for example, rubber or sponge. Since the omnidirectional camera 1 is mounted on a vehicle, the omnidirectional camera 1 may also vibrate due to vibration (from the vehicle body) from the vehicle, particularly during traveling. Therefore, the vibration from the vehicle can be suppressed by interposing such a damper 9.
[0022]
Note that the omnidirectional camera 1 may have sensitivity in the visible light region or sensitivity in the infrared region, for example. Although this differs depending on the application, for example, when it is assumed that a sufficient recognition function is desired in a state where the visual field inside or outside the vehicle is dark, it is preferable to employ one having sensitivity in the infrared region. For example, it may be used in a system called a “night vision system” or the like that is used to assist the driver in the nighttime by photographing the situation in front of the vehicle. Alternatively, in the vehicle, for example, when it is desired to take an image of the situation inside the vehicle when it is stolen at night, an infrared camera may be used.
[0023]
Thus, according to the omnidirectional camera 1 of the present Example mounted in the vehicle, the following effects are exhibited.
(A) First, since the omnidirectional camera 1 is disposed between the mirror surface portion 2a of the inner mirror 2 and the windshield 4, it may be difficult to obstruct the view from the passenger, particularly the driver. The degree is low.
[0024]
(B) Since the omnidirectional camera 1 according to the present embodiment has a field of view in all directions of 360 degrees in the horizontal direction and in a predetermined portion below the horizontal direction, the outside field of view and the inside field of view can be obtained with one camera. Can be secured. In particular, since it has a horizontal visual field with reference to the vicinity of the lower end of the inner mirror 2, it is suitable for occupant detection and vehicle surrounding monitoring. For example, in the case of a monitoring camera for a driver's snoozing prevention system, it is necessary to photograph the driver's face, but in this embodiment, the height of the driver's face can be taken into consideration. In addition, even when it is considered to be used as a surveillance camera around a vehicle for capturing the appearance of an object that is intended to be stolen, a field of view up to a sufficient height can be secured.
[0025]
The lens unit 1a of the omnidirectional camera 1 is disposed so as to protrude slightly below the lowest position of the inner mirror 2, and this protrusion amount is considered so that the inner mirror 2 does not enter the in-vehicle visual field. As a minimum amount. Therefore, the inner mirror 2 does not enter not only the outside view but also the inside view. Nevertheless, since the omnidirectional camera 1 does not protrude so much from below the inner mirror 2, it is possible to suppress the occupant's front view of the vehicle from being blocked as much as possible.
[0026]
(C) In the case of the present embodiment, the optical axis of the omnidirectional camera 1 is made to coincide with the vertical direction (the height direction of the vehicle). Therefore, as shown in FIG. 1A, the maximum heights of the in-vehicle visual field and the external visual field are equal. Therefore, it is effective when it is desired to generally monitor not only the front of the vehicle but also the surroundings of the vehicle, for example, to prevent theft. Of course, the optical axis may be shifted from the vertical direction. For example, when it is desired to make the vehicle exterior visual field in the windshield direction relatively high, if the optical axis is tilted toward the windshield 4, the vehicle exterior visual field can be grasped to a relatively higher range than the vehicle interior vision.
[0027]
(D) Further, the camera case 3 of the present embodiment is disposed near the center in the left-right direction of the inner mirror 2. When adjusting the left and right inclination of the inner mirror 2, the amount of movement of the left and right ends is relatively large. Therefore, when the vehicle-mounted omnidirectional camera is disposed in such a large movement amount, a relatively large amount of separation from the inner mirror 2 toward the windshield 4 must be ensured in order to prevent interference. Don't be. Then, in order to prevent the inner mirror 2 from blocking the camera field of view as much as possible, the amount by which the omnidirectional camera 1 protrudes downward from the lowest position of the inner mirror 2 must be relatively increased. On the other hand, if the inner mirror 2 is arranged in the vicinity of the center in the left-right direction as in this embodiment, the amount of downward projection from the lowest position of the inner mirror 2 of the omnidirectional camera 1 is reduced, and the occupant moves forward in the vehicle. The degree to which the in-vehicle omnidirectional camera blocks the field of view is also relatively low.
[0028]
(E) Since the omnidirectional camera 1 is fixed to the camera case 3 via the damper 9, the transmission of vehicle vibration to the omnidirectional camera 1 is suppressed, and the imaging function of the omnidirectional camera 1 is improved. Can do.
[Second Embodiment]
FIG. 2A is a schematic explanatory diagram showing the mounting position and the like of the omnidirectional camera 1 in the second embodiment. In addition, the same code | symbol is attached | subjected about the structure similar to the said 1st Example shown with reference to FIG. 1, and detailed description is abbreviate | omitted.
[0029]
In the first embodiment, the omnidirectional camera 1 is arranged in the camera case 3 fixed to the windshield 4 (see FIG. 1). In the second embodiment, as shown in FIG. The camera case 3 in which the omnidirectional camera 1 is housed is movably connected to the inner mirror stay 5 and the glass fixing portion 7. Specifically, the omnidirectional camera 1 is built in the lower half of the substantially cylindrical camera case 3 in which the abdomen swells, and the free ends of the two connecting rods erected from the upper surface of the camera case 3 It is connected to the inner mirror stay 5 by a camera movable connecting portion 3a provided on the inner mirror stay. 2A shows only one connecting rod, the other is hidden behind the inner mirror stay 5, and two connecting rods are arranged so as to sandwich the inner mirror stay 5. Yes.
[0030]
By the way, the inner mirror stay 5 of the present embodiment is arranged so as to extend in the longitudinal direction of the vehicle (slightly downward toward the rear of the vehicle), and further by the stay coupling portion 5b which is a coupling portion with the glass fixing portion 7, The vehicle can be rotated in the longitudinal direction. On the other hand, as described above, since the camera movable connecting portion 3a provided at the free end of the connecting rod on the upper surface portion of the camera case 3 is rotatably connected to the inner mirror stay 5, the camera case 3 is also provided in the vehicle longitudinal direction. It can be rotated.
[0031]
The camera case 3 is connected to the glass fixing portion 7 by a link arm 8 on the upper surface portion. Both ends of the link arm 8 are rotatably connected to the camera case 3 and the glass fixing part 7, respectively, and still allow the camera case 3 to rotate in the front-rear direction.
[0032]
If the inner mirror stay 5 can be rotated up and down, the degree of freedom in adjusting the angle of the inner mirror 2 in the vertical direction is increased. However, when the camera case 3 is simply fixed to the inner mirror stay 5, the tilt of the optical axis of the omnidirectional camera 1 is shifted by rotating the inner mirror stay 5 up and down, and the relative field of view changes. End up. On the other hand, in the case of the present embodiment, since it has the above-described configuration, the omnidirectional camera 1 is operated by the camera movable connecting portion 3a and the movable connecting portion 8a of the link arm 8 even when the inner mirror stay 5 rotates in the vertical direction. The relative orientation of the optical axis is maintained, and the relative viewing direction is not changed.
[0033]
When the camera case 3 is attached to the inner mirror stay 5 in this way, it is easy to set the horizontal center of gravity of the entire camera case 3 including the omnidirectional camera 1 to coincide with or near the center of gravity of the inner mirror stay. Therefore, it is advantageous in that the vibration is reduced or the load on the hinge coupling portion is reduced.
[0034]
Of course, in this case as well, the camera case 3 is disposed between the inner mirror 2 and the windshield 4 and is disposed near the center in the left-right direction of the inner mirror 2. For this reason, the visual field from the driver is not obstructed or the degree is very low. Further, since the degree of interference with the left / right tilt adjustment movement of the inner mirror 2 is low, the amount of separation from the inner mirror 2 toward the windshield 4 may be relatively small so that the inner mirror 2 does not block the camera field of view. For this purpose, the amount by which the omnidirectional camera 1 protrudes downward from the lowest position of the inner mirror 2 may be relatively small.
[0035]
Also in this embodiment, since the omnidirectional camera 1 is fixed to the camera case 3 via the damper 9, it is possible to suppress the vehicle vibration from being transmitted to the omnidirectional camera 1, and the imaging function of the omnidirectional camera 1. Accuracy can be improved.
In addition, the basic effects mentioned in the first embodiment can be obtained in the second embodiment as well.
[0036]
[Third embodiment]
FIG. 2B is a schematic explanatory diagram showing the mounting position and the like of the omnidirectional camera 1 in the third embodiment. In addition, the same code | symbol is attached | subjected about the structure similar to the said 1st Example shown with reference to FIG. 1, and detailed description is abbreviate | omitted.
[0037]
In the first and second embodiments, the omnidirectional camera 1 is housed in the camera case 3 separate from the inner mirror 2, but in the third embodiment, as shown in FIG. 1 was stored in the mirror case portion 2 b of the inner mirror 2. That is, the inner mirror 2 is integrated with the omnidirectional camera 1.
[0038]
In this case, the mirror case portion 2b is not movable with respect to the inner mirror stay 5, but is fixed in a stationary manner. On the other hand, the mirror surface portion 2a is attached to the mirror case portion 2b so that its inclination can be changed. In the present embodiment, the inclination of the mirror surface portion 2a can be changed in the vertical direction and the horizontal direction around a rotation shaft (not shown) provided in the mirror case portion 2b.
[0039]
On the other hand, the omnidirectional camera 1 of the present embodiment is disposed near the center in the left-right direction and near the lower end of the mirror case portion 2b. Since it is arranged near the center in the left-right direction, when it is positioned so as not to interfere even if the mirror surface portion 2a rotates in the left-right direction, it can be disposed at a position relatively close to the mirror surface portion 2a. Therefore, the mirror case portion 2b can be relatively downsized. Further, the arrangement near the lower end will be specifically described. Similar to the first or second embodiment, the lens unit 1a is arranged so as to be at the lowermost end of the omnidirectional camera 1, and the optical axis thereof is arranged to coincide with the vertical direction. Further, the lens portion 1a is slightly protruded downward from the mirror case portion 2b. Thereby, the mirror case part 2b becomes a position where the omnidirectional camera 1 does not block the field of view, and the omnidirectional camera 1 is integrated with the inner mirror 2 in view of the interior view of the vehicle, and the design is also neat. Become.
[0040]
In addition, the basic effects mentioned in the first embodiment can be obtained in the second embodiment as well.
In the above description, the mirror case portion 2b is fixed in a stationary manner with respect to the inner mirror stay 5. However, for example, the mirror case portion 2b may be configured to rotate only in the left-right direction without rotating in the vertical direction. . This is because the direction of the optical axis of the omnidirectional camera 1 itself changes when the mirror case part 2b rotates in the vertical direction, but the direction of the optical axis itself does not change even when the mirror case part 2b rotates in the horizontal direction. It is. If the omnidirectional camera 1 is arranged near the center in the left-right direction of the mirror case part 2b as described above, the relative position of the omnidirectional camera 1 itself hardly changes even if the mirror case part 2b rotates in the left-right direction. This is because no particular problem occurs.
[0041]
In the example shown in FIG. 2B, the lens portion 1a is protruded slightly downward from the mirror case portion 2b. However, the omnidirectional camera 1 including the lens portion 1a is completely within the mirror case portion 2b. It is good also as a structure to accommodate. In that case, it is conceivable that the portion (near the lower end) where the field of view is secured in the mirror case portion 2b is, for example, a dichroic filter that is a thin film that transmits light of a predetermined color. In this way, even if the omnidirectional camera 1 is completely hidden in the mirror case part 2b by human eyes, the visual field is not hindered.
[0042]
[Others]
(1) In the first or third embodiment, the camera case 3 is suspended and fixed inside the windshield 4, but is fixed to the glass fixing portion 7 for fixing the inner mirror 2 to the windshield 4. You may make it do. Further, it may be fixed to the lean force of the ceiling 10.
[0043]
(2) In the above-described embodiment, the omnidirectional camera 1 is configured such that the lens portion 1a comes to the lowest end when securing the in-vehicle / out-of-vehicle field of view as shown in FIG. For example, a configuration in which the light receiving element portion is located below the optical system portion where light from an omnidirectional field first enters may be employed. For example, a hyperbolic mirror having a large curvature reflects downward light from “a field of view at 360 degrees in all directions in at least a substantially horizontal direction and a predetermined portion below the substantially horizontal direction” as shown in FIG. The reflected light may be received by a light receiving element provided below.
[0044]
However, in such a configuration, since the portion including the light receiving element protrudes further downward from the lower end of the inner mirror 2, the degree of blocking the occupant's front view is relatively large. Therefore, from the viewpoint of not blocking the front field of view as much as possible, it is preferable that the “optical system part where light from all directions of the field first enters” as in the above-described embodiment comes to the lowest end.
[0045]
(3) Various applications of the omnidirectional camera 1 of this embodiment are conceivable. In addition to the specific examples described above, examples of using the photographing result in the field of view outside the vehicle include a rain sensor that catches raindrops and the like adhering to the windshield 4 and determines a rainfall situation. Moreover, as what uses the imaging | photography result in the visual field of a vehicle interior direction, using it as a camera for detecting the temperature of a passenger | crew, a seat, etc. in order to control an air conditioner is mentioned.
