For an industrial camera adopting a laser speckle-like texture projector, as the speckle in the target direction is matched, the smaller the number of repeated speckles in the target direction is, the more the accuracy of binocular matching calculation is improved. In the embodiment shown in fig. 5B, the axis of symmetry S is tilted with respect to the optical center line P, that is, the projector 34 is rotated by a certain angle, so that the number of repetitions of the speckle in the target direction (e.g., horizontal direction) can be reduced, and the accuracy of the depth information captured by the industrial camera 100 can be improved to some extent.

As shown in fig. 1A, the first projecting part 34a and the second projecting part 34b of the projector 34 have different projecting directions, i.e. form a certain included angle α, so that the projector 34 has a larger projecting range, and the range of viewing angles photographed by the industrial camera 100 can be increased.

In some embodiments of the present disclosure, if there is no particular requirement for the photographing viewing angle range of the industrial camera 100, the projection directions of the first and second projecting

parts

34a and 34b of the projector 34 may also be the same.

Some embodiments of the present disclosure also provide an industrial camera to improve reliability of the industrial camera in different application scenarios.

As shown in fig. 1A, 1B, 1C, 2, 3 and 6B, an industrial camera 100 provided by some embodiments of the present disclosure includes a camera module 30, where the camera module 30 includes a bracket 31, a main board 32, a projector 34 and at least one camera 33. The bracket 31 includes a heat dissipation portion 312. The main board 32 is fixed to the back side of the bracket 31, and includes a cpu 321, and the cpu 321 is opposite to the heat dissipation portion 312. The projector 34 is fixed to the front side of the bracket 31 and faces the heat dissipation portion 312. At least one camera 33 is fixed to the bracket 31 and located between the main plate 32 and the bracket 31, and the bracket 31 is provided with a camera mounting hole 311 corresponding to each camera 33.

The two most important heating elements (i.e., the projector 34 and the cpu 321) of the camera module 30 are respectively disposed at the front and rear sides of the heat dissipation portion 312 and are thermally conductive therewith, so that the heat dissipation path can be greatly shortened, the heat dissipation efficiency can be improved, and the design of the heat dissipation structure is compact.

The embodiment of the present disclosure is not particularly limited with respect to the specific structural type of the industrial camera 100. In some embodiments of the present disclosure, the industrial camera 100 is a binocular industrial camera, and the camera module 30 includes a projector 34 (e.g., a single lens projector or a dual lens projector), a first infrared camera 33a (IR camera), a second infrared camera 33b (IR camera), and a color camera 33c (RGB camera). In other embodiments of the present disclosure, the industrial camera is a binocular industrial camera, the camera module includes a projector (e.g., a single lens projector or a dual lens projector), a first infrared camera, and a second infrared camera, and does not include a color camera. In still other embodiments of the present disclosure, the industrial camera is a monocular industrial camera and the camera module includes a projector and a single infrared camera.

The particular heat dissipation design employed for heat dissipation portion 312 is not limited. For example, the heat dissipation part 312 may include a plurality of heat dissipation fins 3121, and/or have a plurality of heat dissipation through holes 3122. As shown in fig. 3, in this embodiment, the heat dissipating part 312 includes a plurality of heat dissipating fins 3121, and the heat dissipating part 312 has a plurality of heat dissipating through holes 3122, and an arrangement direction of the plurality of heat dissipating fins 3121 is the same as an extending direction of the plurality of heat dissipating through holes 3122. The structural design can remarkably increase the heat dissipation area of the heat dissipation part 312, and the heat is uniformly dispersed. In addition, the heat dissipation portion 312 is compact in structure, light in weight, and simple in manufacturing process.

In some embodiments, the surface of the heat dissipation part 312 is provided with a heat dissipation enhancing layer (not shown), and the heat dissipation enhancing layer has a heat dissipation coefficient greater than that of the internal material of the heat dissipation part 312. The heat dissipation enhancing layer may be a graphite layer or a black oxide layer, for example. The heat dissipation enhancement layer not only can slow down or even avoid the oxidation of internal materials, but also can further improve the heat dissipation efficiency. Especially, the heat dissipation reinforcing layer of black material is more favorable to in time dispelling the heat because the heat radiation of black material is bigger than other colour materials.

As shown in fig. 3, in some embodiments, an insulating thermal pad 3123 is provided between the heat sink portion 312 and the motherboard 32. The insulating heat conduction pad 3123 has insulating property and heat conduction property, and can reduce risks such as short circuit of a circuit. The insulating thermal pad 3123 may be disposed on the bracket 31 or fixed to the main board 32.

As shown in fig. 2, in the embodiment of the present disclosure, the bracket 31 is designed to have an integrated structure, a camera mounting hole 311 is provided corresponding to each camera 33, the camera 33 is located between the main board 32 and the bracket 31 after being mounted, a lens of the camera 33 extends into the camera mounting hole 311 (i.e., is located in a cavity of the camera mounting hole 311), and a part of a base of the camera 33 may also be located in the camera mounting hole 311 so as to be assembled with the camera mounting hole 311. Because the structure of support 31 is firm, can resist the bending stress of all directions, has better cladding nature to camera 33, consequently, can improve the stability of camera 33 installation on support 31 to guarantee the positioning accuracy of camera 33's optical axis, improve the quality of shooing.

As shown in fig. 5A, in some embodiments, the projector 34 is a laser speckle-like texture projector that is positioned between the first infrared camera 33a and the second infrared camera 33b and includes a first projecting portion 34a and a second projecting portion 34b that are symmetrically arranged with respect to an axis of symmetry S. The optical center connecting line P of the first infrared camera 33a and the second infrared camera 33b is orthogonal to the symmetry axis S, and the optical center of the color camera 33c is located on the optical center connecting line P.

Fig. 5B shows other embodiments of the present disclosure, which are different from the embodiment shown in fig. 6A in that an included angle β between a connecting line P of optical centers of the first infrared camera 33a and the second infrared camera 33B and the symmetry axis S is greater than zero and smaller than 90 degrees. The specific angle of the included angle β is not limited.

The laser speckle-shaped texture projector is internally provided with a diffractive optical element for shaping infrared beams. The projector 34 emits a dot matrix infrared beam toward the monitor object, thereby forming a dot matrix pattern on the monitor object. The first infrared camera 33a and the second infrared camera 33b collect dot matrix patterns formed on the monitored object in respective field angles, and the central processing unit matches spots in a target direction (for example, a horizontal direction) by using a binocular matching algorithm according to the dot matrix patterns collected by the two cameras, so that depth information of the monitored object in a space is obtained.

For an industrial camera adopting a laser speckle-like texture projector, as the speckle in the target direction is matched, the smaller the number of repeated speckles in the target direction is, the more the accuracy of binocular matching calculation is improved. In the embodiment shown in fig. 5B, the symmetry axis S is disposed obliquely with respect to the optical center connecting line P, that is, the projector 34 is rotated by a certain angle compared to the embodiment shown in fig. 5A, so that the number of repeated spots in the target direction (e.g., horizontal direction) can be reduced, and the accuracy of the depth information captured by the industrial camera can be improved to some extent.
