Description

Technical Field

[0001] The utility model relates to the field of underwater image processing, in particular to an underwater binocular camera pitch device. Background Art

[0002] With the rapid development of ocean development, people are exploring the marine environment more deeply. In the field of underwater optical detection, fixed underwater cameras cannot meet the use requirements in many scenarios, and most of the cameras used in the underwater field are single-lens (monocular) cameras. In underwater scenes that require binocular cameras and multi-angle observation, angle adjustment is required.

[0003] Binocular stereo vision is a very good way to explore underwater environments. As a non-contact three-dimensional measurement method, binocular stereo vision can effectively eliminate the defects of traditional monocular vision measurement and improve measurement accuracy and stability. In the field of underwater vision research, binocular stereo vision technology has also been widely used and achieved good results.

[0004] Existing underwater binocular vision systems cannot be used in the deep sea or in the water for a long time. Most of them are fixed in position and cannot be adjusted in angle. They cannot meet the requirements in special underwater scenes (such as underwater robots equipped with underwater manipulators, multi-angle underwater monitoring, etc.). At present, there is a solution to use underwater servos for angle adjustment, but due to the large size of underwater binocular cameras and the large torque of the underwater servos used, it undoubtedly increases the size and cost of the entire system.

[0005] In order to solve the above technical problems, the utility model designs an underwater binocular camera pitch device. Utility Model Content

[0006] The utility model provides an underwater binocular camera pitch device, which aims to solve the problem that the existing underwater binocular vision system cannot be used in water for a long time and cannot adjust the angle. The technical solution is as follows:

[0011] Based on the above technical solution, the camera module has multiple lenses, and the binocular transparent glass is arranged at the lens position.

[0012] Based on the above technical solution, a rear cover sealing ring is arranged between the sealed cabin of the binocular system and the rear cover.

[0013] Based on the above technical solution, the bearing is made of zirconium oxide.

[0014] Preferably, the underwater binocular vision system is fixed on the binocular base by vision system bolts.

[0015] Beneficial Effects

[0016] Compared with the prior art, the utility model has the following beneficial effects: on the one hand, through the pitch adjustment of the underwater pitch platform, the camera can adjust the viewing angle upward or downward, so that image information at different heights and depths can be captured more flexibly. On the other hand, the device has strong sealing performance and is equipped with multiple sealing ring protection devices.

[0027] The underwater tilting platform 4 is fixed on the support seat 1 by fixing bolts 2, a pad column 3 is connected between the support seat 1 and the stator bearing sleeve 6, the output end of the underwater tilting platform 4 is connected to the bearing 7, the stator bearing sleeve 6 is sleeved on the bearing 7 and rotatably connected to the bearing 7, a rotor bearing sleeve 8 is installed on the bearing 7, the binocular pad 9 is connected to the bearing sleeve 8, and the underwater binocular vision system 5 is detachably mounted on the binocular pad 9.

[0028] like Figure 4As shown, the underwater binocular vision system 5 includes a binocular system sealed cabin 51, a rear cover 52, binocular transparent glass 53, a fixed bracket seat 54, a transmission PCB board 55, a camera module 56 and a cable 58. The camera module 56 is arranged in the binocular system sealed cabin 51, the binocular transparent glass 53 is connected to the binocular system sealed cabin 51 through a binocular bolt 57, the fixed bracket seat 54 is installed in the binocular system sealed cabin 51, the transmission PCB board 55 is installed on the fixed bracket seat 54, the rear cover 52 is screwed to the binocular system sealed cabin 51, and a cable 58 is arranged on the rear cover 52, and the cable 58 is connected to the transmission PCB board 55. A binocular O-ring 59 is arranged between the binocular system sealed cabin 51 and the binocular transparent glass 53.

[0029] The camera module 56 has multiple lenses, and the binocular transparent glass 53 is set at the lens position.

[0030] A rear cover plate sealing ring 521 is provided between the binocular system sealed cabin 51 and the rear cover plate 52 .

[0031] The bearing 7 is made of zirconium oxide. Zirconia is almost unaffected by corrosive media and is very suitable for working in corrosive environments, such as the chemical, offshore or petrochemical industries. The rolling elements of the zirconia bearing 7 are much lighter, which reduces the centrifugal force on the outer ring by about 40%. This not only reduces the overall weight, but also significantly increases the service life of the bearing. The thermal expansion coefficient of zirconium oxide is smaller than that of steel, which means that in an environment with large temperature changes, the bearing can maintain a more stable gap and reduce stress and wear caused by temperature differences. High hardness and deformation resistance: Zirconia ceramics have a high elastic modulus and hardness, and are not easy to deform when subjected to force, which helps to increase the working speed and maintain a high operating accuracy.

[0032] The underwater binocular vision system 5 is fixed on the binocular cushion 9 by a vision system bolt 91. The underwater binocular vision system 5 is disassembled by the vision system bolt 91, which is convenient and quick, and a plurality of vision system bolts 91 can be provided to improve the stability of the connection.

[0033] The device is lightweight and can operate underwater for a long time. The underwater binocular vision system 5 is connected to the underwater system assembly, and the shore-based operator can send commands to the system to control the underwater pitch platform 4 to pitch the underwater binocular vision system 5 at a fixed angle, with an angle control range of 0 degrees to 359 degrees. The system has high sealing performance and can be used in an environment with a water depth of 300 meters; it uses zirconium oxide bearings, which will not rust after being immersed in seawater for a long time and can maintain the smoothness of the bearings; it improves the existing bearingless or single-sided bearings and adopts a two-sided bearing method to completely offset the gravity of the underwater binocular vision system 5, so that the underwater pitch platform 4 does not bear additional gravity, which plays a good protective role on the axis of the underwater platform.

[0034] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
