通过对运动捕获系统的分析，建立了场景中多摄像机和目标的表示模型；基于摄像机透视投影模型，建立了多摄像机最大覆盖约束、定位精度约束和空间点遮挡效应的数学模型；综合上述约束，提出了多摄像机布局优化问题的优化目标函数，并用粒子群算法进行了求解。基于实际运动捕获系统的实验表明，该方法是有效的。
According to the analysis on motion capture systems,the representation models of multi-camera and target in the scene are set up.The mathematical models for multi-camera maximum coverage constraint,positioning accuracy constraint and occlusion effects of the space points are developed,based on camera perspective projection model.By synthesizing the aforementioned constraints,an optimization objective function for multi-camera layout optimization problem is proposed.The problem is solved by using particle swarm optimization(PSO) method.The experiments based on real motion capture system indicate that the method is effective.
