提出了一种测量网络节点位姿的优化方法。建立了网络节点参数的数学模型,分析了位姿参数对测量精度的影响机理,仿真获得了位姿参数最优取值范围和优化初解。对标定板上标志点间距离进行三维视觉测量,结果表明,优化处理后测量相对误差约降低了 0.6%。
Abstract
An optimization method for measuring network node pose is proposed. The mathematical model of network node parameters is established, the influence mechanism of pose parameters on the measurement accuracy is analyzed, and the optimal range and optimal initial solution of pose parameters are obtained by simulation. Distance between the mark points on calibration plate is measured by three-dimensional vision. Experimental results show that the relative error of measurement after the optimization is reduced by 0.6%.
