Embodiment 1

[0031] figure 1 It is a flowchart of a camera configuration method provided in Embodiment 1 of the present invention. The execution subject of this embodiment may be a computer device or a functional unit in the computer device. This embodiment specifically includes steps S101 to S103, which are described in detail as follows:

[0032] S101: In the preset visualization area, determine a preset number of valid camera configuration modes according to the height information of the cameras and the angle between the visual axis of the cameras and the horizontal plane.

[0033] The preset visualization area can be any size created by the user in the optical motion capture system, and contains the simulated area of ​​obstacles such as columns and walls. In the preset visualization area, the user can further set camera parameters, including the set total number of cameras, and the set total number of cameras can be actually adjusted.

[0034] The camera configuration mode can be dete...

Embodiment 2

[0059] figure 2 It is a flow chart of a camera configuration method provided in Embodiment 2 of the present invention. The execution subject of this embodiment may be a computer device or a functional unit in a computer device. The difference between this embodiment and Embodiment 1 is that the detailed description How to determine a preset number of effective camera configurations according to the height information of the cameras and the angle between the visual axis of the cameras and the horizontal plane, that is, this embodiment specifically describes step S101. The details are as follows:

[0060] S201: In the preset visualization area, randomly generate multiple camera configuration modes according to the set number of cameras.

[0061] The preset visualization area can be any size created by the user in the optical motion capture system, and contains the simulated area of ​​obstacles such as columns and walls. In the preset visualization area, the user can further s...

Embodiment 3

[0080] image 3 It is a flow chart of a camera configuration method provided by Embodiment 3 of the present invention. For Embodiment 3, reference may be made to Embodiment 2. For steps S301-303, reference may be made to Steps S201-203 in Embodiment 2, which will not be repeated here.

[0081] The difference between the third embodiment and the second embodiment is that, after calculating the configuration cost value of each configuration mode according to the determined effective camera configuration mode, when calculating the configuration cost value of each configuration mode, the effective camera configuration mode is also considered In , whether the intersection of the camera boresight and the horizontal plane falls within the visualization area affects the configuration cost value. That is to say, when calculating the configuration cost value of the camera configuration mode, in addition to considering the number of visible cameras at the point to be tested and the relat...

Abstract

A camera configuration method and device, comprising: in a preset visualization area, determining a preset number of effective camera configuration modes according to the height information of the cameras and the angle between the visual axis of the camera and the horizontal plane; Calculate the configuration cost value of each configuration mode according to the above camera configuration mode; determine the final camera configuration mode according to the configuration cost value. In the embodiment of the present invention, since the configuration cost value is calculated according to the effective camera configuration method determined according to the height information of the camera and the angle between the visual axis of the camera and the horizontal plane, it is avoided to include invalid configuration methods when calculating the configuration cost value. Among them, the calculated configuration cost is more reasonable, so that the camera configuration method is also more reasonable, while ensuring the motion capture effect, it is more reasonable to configure an appropriate number of motion capture cameras, making the camera configuration more economical and reasonable.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a camera configuration method and device. Background technique [0002] In the process of optical motion capture, the price of motion capture cameras is very expensive. It is very important to save costs by rationally configuring an appropriate number of motion capture cameras while ensuring the motion capture effect. Therefore, how to rationally configure an appropriate number of motion capture cameras has become an urgent problem to be solved. [0003] The prior art discloses a camera layout scheme. The idea of ​​the camera layout scheme is: first randomly generate a certain number of camera configurations, and then calculate the number of visible cameras for each point to be tested in each camera configuration, Finally, according to the number of visible cameras at each point to be tested, the configuration cost of each camera configuration is calculated. When calculating the ...
