Optical motion capture is the task of motion capture by monitoring and tracking of specific spots on the target. For any point in space, as long as it can be seen by two cameras at the same time, the spatial position of the point at the moment can be determined according to the images shot by the two cameras and the camera parameters at the same moment, and when the cameras continuously shoot at a high enough speed, the motion track of the point can be obtained from the image sequence.

When optical motion capture is performed, field debugging of a three-dimensional motion capture camera is often required, and it is very important to enable a user to obtain a better debugging experience through a proper structural design.

The existing three-dimensional motion capture camera usually adopts a multi-support central design, and in the actual operation process, because the multi-support blocks heat dissipation and influences the hand operation space of a user, the problems of poor heat dissipation capability and inconvenient operation exist in the prior art.

In order to solve the above problems, a three-dimensional motion capture camera is shown in the present application, fig. 1 is a front view of the three-dimensional motion capture camera shown in the exemplary embodiment of the present application, and fig. 2 is a side view of the three-dimensional motion capture camera shown in the exemplary embodiment of the present application, and as shown in fig. 1 and 2, the camera includes: the device comprises a front panel 1, a lens 2, a connecting pipe 3 and a mainboard module 4;

Since the first lens through hole 11 is designed to be eccentric, the connecting tube 3 is disposed on the side of the edge of the front panel 1 away from the lens 2, so that the stability of the overall structure of the three-dimensional motion capture camera can be increased.

In some embodiments, the height of the front panel 1 near the lens 2 is higher than the height of the motherboard template 4 near the lens 2. By adopting the embodiment, because the first lens through hole 11 in the front panel 1 adopts an eccentric design, and the connecting pipe 3 is arranged on one side of the edge of the front panel 1 far away from the lens 2, the front panel 1, the lens 2, the connecting plate 3 and the motherboard module 4 form a right trapezoid structure under the embodiment, and the stability is better.
