Description

Technical Field

[0001] The utility model relates to the field of binocular cameras, in particular to a binocular camera and an aircraft. Background Technique

[0002] Binocular camera sensor products are mainly used in: autonomous driving and advanced driver assistance systems (ADAS); robot navigation and obstacle avoidance; UAV aerial photography and mapping; security monitoring; industrial inspection and automation; consumer electronics; medical diagnosis and surgical assistance; new retail and business analysis, etc.

[0003] The binocular camera calculates depth information by using the parallax of the same scene captured by the left and right lenses. The parallax is inversely proportional to the object distance. The farther the distance, the smaller the parallax. In order to obtain depth measurement with sufficient accuracy within a certain distance range, it is necessary to set an appropriate baseline length. A wider baseline is beneficial to improving the depth resolution ability of distant objects, but may result in too small parallax of nearby objects, making it difficult to calculate accurately. On the contrary, a narrower baseline helps to improve the depth measurement accuracy of nearby objects, but may limit the detection ability of distant objects. Therefore, the selection of the baseline should be weighed according to the expected depth measurement range and accuracy requirements of the system.

[0004] From the perspective of structural design, for a narrower baseline, the product length dimension is small, the structural stress deformation is small, and the structural design difficulty is small; while for a wider baseline, the product length dimension is large, the structural stress deformation is large, and the structural design difficulty is large. Conventional binocular cameras in the market usually do not require depth measurement of ultra-distant objects due to the usage scenarios, and a baseline within 200mm generally can meet the usage requirements. For the autonomous driving and driver assistance systems in the field of manned aircraft, due to the large field of view and long ranging distance, binocular camera products with a wider baseline are often required to support. The structure of a binocular camera with a wide baseline and long dimension is usually: the lens is installed between the front housing and the rear housing through a lens holder to form a lens assembly, and then two sets of lens assemblies are respectively assembled at both ends of the structural cross beam. The structural strength of the binocular camera often cannot meet the usage requirements; or the structural strength meets the requirements, but the product weight increases, which does not meet the lightweight requirements of the aircraft product. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is how to provide a lightweight binocular camera with a wide baseline.

[0006] The technical solution of the present utility model to solve the above technical problems is as follows: A binocular camera includes a lens module and a rear housing. Both ends of the front side of the rear housing are provided with lens mounting grooves. There are two groups of lens modules, and the two groups of lens modules are arranged in one-to-one correspondence with the two lens mounting grooves. The lens module includes a lens, a front cover plate, and a circuit board. One end of the lens passes through the front cover plate and is fixedly connected to the front cover plate.

[0007] The beneficial effects of the present utility model are: The binocular camera integrally designs the two lens rear shells and the structural cross beam to form the rear housing. The lens and the circuit board are directly fixed to the front cover plate to form the lens module, and the assembly is simple. The front cover plate replaces the existing lens seat, reducing the cross beam and the two lens seats, achieving the effect of weight reduction.

[0040] Embodiment 1

[0041] As Figures 1-10 shown, this embodiment provides a binocular camera, which includes a lens module and a rear housing 5. Both ends of the front side of the rear housing 5 are provided with lens mounting grooves. There are two groups of lens modules, and the two groups of lens modules are arranged in one-to-one correspondence with the two lens mounting grooves. The lens module includes a lens 2, a front cover plate 3 and a circuit board 4. One end of the lens 2 passes through the front cover plate 3 and is fixedly connected to the front cover plate 3. The circuit board 4 is located behind the lens 2, and the circuit board 4 is fixedly connected to the rear side of the front cover plate 3. The front cover plate 3 is fixedly connected to the corresponding lens mounting groove.

[0042] In the binocular camera of this embodiment, the two lens rear shells and the structural cross beam are integrally designed to form the rear housing. The lens 2 and the circuit board 4 are directly fixed to the front cover plate 3 to form the lens module, and the assembly is simple. The front cover plate 3 replaces the existing lens seat, reducing the cross beam and the two lens seats, achieving the effect of weight reduction. At the same time, due to the reduction of parts, the effect of cost reduction is also achieved.

[0043] Optionally, the lens 2 is fixed to the front cover plate 3 with glue or is fixed to the front cover plate 3 by screw connection.

[0044] Optionally, the circuit board 4 is fixedly connected to the front cover plate 3 with screws or glue.

[0045] Optionally, the circuit board 4 is a PCBA or other form of circuit board.

[0046] In one specific example, the materials of both the front cover plate 3 and the rear housing 5 are aluminum alloy.

[0047] Optionally, the front cover plate 3 is fixedly connected to the rear housing 5 with a plurality of first screws 1; or, the front cover plate 3 and the rear housing 5 are connected by a laser welding process.

[0048] In one specific example, a sealing strip is clamped between the front cover plate 3 and the front end face of the lens mounting groove to increase the sealing performance between the front cover plate 3 and the rear housing 5.

[0049] Embodiment 2

[0050] Based on Embodiment 1, the rear housing 5 includes a cross beam and two mounting blocks 59. The two mounting blocks 59 are integrally formed with both ends of the cross beam respectively, and the mounting blocks 59 have lens mounting grooves.

[0051] The integral formation of the cross beam and the two mounting blocks 59 reduces the assembly process and improves the assembly efficiency.

[0052] Based on the above solution, the cross beam includes an upper beam 52 and a lower beam 53. The upper beam 52 and the lower beam 53 are arranged at an interval up and down. Both ends of the upper beam 52 are integrally formed with the two mounting blocks 59 respectively, and both ends of the lower beam 53 are integrally formed with the two mounting blocks 59 respectively.

[0064] On the basis of any of the above solutions, both ends of the cross beam are bent upward, and a lower rib plate 54 is connected between the lower side of the end of the cross beam and the corresponding mounting block 59.

[0065] As Figure 3 shown, the cross beam is designed in an arc shape, and the structural strength of the connection between the lower side of the cross beam and the mounting block 59 is increased through the lower rib plate 54.

[0066] Specifically, the lower rib plate 54 is integrally formed with the lower beam 53 and the mounting block 59.

[0067] On the basis of any of the above solutions, both ends of the cross beam are bent forward, and a rear rib plate 55 is connected between the rear side of the end of the cross beam and the corresponding mounting block 59.
