Method and device for optimizing camera position variable, equipment and storage medium

Abstract

The invention relates to the field of motion capture, and discloses a method, device and equipment for optimizing a camera position variable and a storage medium, which are used for ensuring the effectiveness and uniformity of a randomly initialized population, reducing the complexity of camera position variable and variable calculation and improving the calculation efficiency of subsequent genetic algorithm crossover variation. The method for optimizing the camera position variable comprises the steps that a top view of an optical motion capture scene is acquired, the top view comprises an inner square frame and an outer square frame which are in central symmetry, the inner square frame and the outer square frame are used for indicating a performer motion area and at least one layer of truss, and each layer of truss is used for arranging multiple cameras; establishing an x-y plane coordinate system for the top view; setting a starting point on the outer square frame, and collecting the path length of each camera layer by layer based on the starting point; acquiring perimeter information of the outer square frame, calculating three-dimensional space coordinates of each camera according to the x-y plane coordinate system, the perimeter information and the path length, and mapping and storing the path length and the three-dimensional space coordinates.

Description

technical field [0001] The invention relates to the field of motion capture, in particular to a method, device, equipment and storage medium for optimizing camera position variables. Background technique [0002] The optical motion capture system is based on a series of optical cameras installed at different positions and angles, and relies on the principle of computer vision technology to track the optical positioning mark points at high speed and precision, so as to complete the capture of the whole body movement of the human body. [0003] In the existing optical motion capture scene, assuming that the given goal is to install n cameras in the optical motion capture scene, installing the camera is actually to determine the pose of each camera, and each camera pose includes the camera X coordinate, camera Y Coordinates, camera Z coordinates, camera horizontal angle, and camera pitch angle are 5 parameters, which are respectively recorded as CameraX, CameraY, CameraZ, Camer...
