  • Structuralparameteroptimizationofbinocular
    研 究了双目视觉测量系统的结构参数优化问题.对双目视觉测量的有效视场约束条件进行了数学 描述,建立了双目视觉坐标测量系统的数学模型.在考虑像点提取误差的条件下,利用误差理论建立了测量 误差模型,并基于待测量的视场范围要求,定义了测量系统结构参数的优化指标。最后,通过枚举法进行了 优化求解.(Studied binocular vision measurement system to optimize the structural parameters of the problem. For the effective measurement of binocular vision bound by the terms of field of view of mathematical description of the establishment of binocular vision coordinate measuring system mathematical model. In considering the error as the point of extraction conditions the use of error theory the establishment of measurement error model and measurement based on the field of view to be the scope of the requirements of the definition of the measurement system parameters to optimize the structure of indicators. Finally, the optimized enumeration method for solving.)
