摘　　要：针对便携式光笔测量系统中椭圆形标志点中心定位的问题进行了研究。依据被测标志点的成像特征,采用坐标数据归一化,并结合加权最小二乘优化目标函数的方法,对椭圆形标志点中心的坐标进行求解。Locating oval marking point center in portable light pen measuring system was studied.According to imaging character of the marking point detected,the normalized coordinate data were combined with weighted least squares method of optimal objective function to have the coordinate of oval marking point center solved.
