Description

Technical Field

[0001] The present invention relates to the technical field of VR motion capture, and particularly to a camera-assisted orientation adjustment device based on VR inertial motion capture. Background Art

[0002] Motion capture is to set trackers at the key parts of a moving object. The Motioncapture system captures the positions of the trackers, and then obtains the data of three-dimensional space coordinates after being processed by a computer. When the data is recognized by the computer, it can be applied in fields such as animation production, gait analysis, biomechanics, and ergonomics. With the rapid development of computer hardware and software technologies and the improvement of animation production requirements, in developed countries, motion capture has entered the practical stage, and many manufacturers have successively launched a variety of commercial motion capture devices. And during the process of motion capture work, the camera is an essential part.

[0003] Chinese Patent Authorization Publication No. CN 222334938 U discloses an inertial motion capture device based on a VR base station, including a bottom frame. Both sides of the inner wall of the bottom frame are fixedly connected with a rectangular hollow column. The position of the rectangular hollow column is close to the middle of the inner wall of the bottom frame. One side of the rectangular hollow column is slidably connected with a connecting block. The top surface of the connecting block is fixedly connected with a mounting plate. Both ends of the mounting plate are slidably connected with both sides of the inner wall of the bottom frame respectively. The advantages of the present invention are as follows: The camera moves further, and the movement trajectories of the mounting plate and the connecting block are vertically crossed, and the movement of the camera at any position inside the bottom frame can be freely adjusted. The position can be adjusted according to the large working area of the inertial motion capture staff in the VR base station, the applicability and motion capture quality are effectively improved, and the adjustment speed is guaranteed. It can be continuously adjusted during the process of inertial motion capture work, greatly saving manpower and the time for position adjustment.

[0004] The above-mentioned existing technical solutions have the following deficiencies: Although the technical solution can realize the direction adjustment of the camera during use, its structure using the bottom frame limits the overall device within a certain range, which is not convenient for moving adjustment according to VR motion capture requirements and site requirements, and there is a certain room for optimization. Therefore, it is necessary to design a camera-assisted orientation adjustment device based on VR inertial motion capture to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a camera-assisted orientation adjustment device based on VR inertial motion capture to solve the problem of inconvenient orientation movement proposed in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A camera-assisted orientation adjustment device based on VR inertial motion capture, including an orientation adjustment table and a moving base, wherein the orientation adjustment table is fixed at the top of the moving base;

[0007] A steering plate is connected to the top of the steering table, and a first electric push rod is fixed to the top of the steering plate. A camera is fixed to the top of the first electric push rod. A second electric push rod is fixed to one side of the inner bottom end of the moving base, and a moving plate is fixed to the output end of the second electric push rod. The moving plate is slidably connected to the inner bottom end of the lifting frame. Adjusting wheels are connected to both ends of the moving plate.

Adjusting grooves are provided inside the connecting plates, and the adjusting wheels are connected to the adjusting grooves. Support legs are fixed to the four corners of the bottom end of the lifting frame. Bottom wheels are evenly fixed to the bottom end of the moving base. A receiving groove is provided inside the steering table, and a lead screw is rotatably connected to the inside of the receiving groove. A threaded sleeve is threadedly connected to the outside of the lead screw. A motor is fixed to one side of the steering table, and the output shaft of the motor is connected to the lead screw.

Threaded grooves are evenly provided at the top inside the wire management rack, and threaded rods are threadedly connected to the inside of the threaded grooves. Positioning plates are connected to the bottom ends of the threaded rods.

[0009] In the above solution, by placing the camera connection cables, such as power cables, video cables, network cables, data cables, etc. into the wire grooves and rotating the threaded rods, the threaded connection with the threaded grooves can drive the positioning plates to descend to limit the cables. That is, the purpose of wire management can be achieved by classifying the cables, which is convenient for combing the lines and improving safety.

[0010] Preferably, limiting blocks are fixed to both sides of the positioning plate, and limiting grooves matching the limiting blocks are provided inside the wire management rack on both sides of the wire groove, and the limiting blocks are connected to the limiting grooves.

[0011] Preferably, the bottom profiles of the wire grooves are all set to be arc-shaped, and protective pads are provided at the bottom inside the wire grooves, and the material of the protective pads is rubber.

[0015] In the above solution, since the dispersion layers are made of high-density foam and the anti-slip layers are made of anti-slip rubber, during use, the high-density foam can disperse the pressure, reducing the impact force of direct downward pressure of the structure, so that the anti-slip effect of the anti-slip rubber can be fully exerted, improving the overall anti-slip support effect.

[0016] Preferably, guide blocks are uniformly fixedly provided inside the lifting frame, guide grooves are uniformly provided outside the moving base, and the guide grooves are all connected to the guide blocks.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The camera-assisted orientation adjustment device based on VR inertial motion capture realizes the function of facilitating auxiliary orientation adjustment and movement;

[0018] When it is necessary to shift the camera, the second electric push rod is started to drive the moving plate to move on the slide rail. The moving plate drives the adjusting wheels on both sides to move in the adjusting groove and move to the lowest point inside the adjusting groove. At this time, the lifting frame is synchronously lifted above through the connecting plate, that is, driving multiple groups of support legs to lift, so that the device can be conveniently shifted via the bottom wheels to meet the VR inertial motion capture requirements of different sites. Further, after reaching the designated position, the second electric push rod drives the adjusting wheels to move to the uppermost side of the adjusting groove to realize the support limitation of the device. The operation is simple and convenient to use. It can be easily switched from one angle to another by moving, reducing the number of times of re-arranging the camera and adjusting the lens, and expanding the shooting range.
