摘　　要：为实现一种成本低、操作简单、精度高、可适用于复杂场景的线结构光标定方法,提出一种基于量块与标定板的复合标定法。通过量块与标定板确定光平面上两条不共线光条纹,拟合光平面方程,建立线结构光系统数学模型,求解光平面坐标系到世界坐标系的转换关系,完成系统的标定。To achieve a line structured light calibration method with low costs,easy operation and high accuracy applicable to complex scenes,a composite calibration method based on the gauge block and calibration target is proposed.Two non-collinear light stripes on the light plane are determined by the gauge block and calibration target,the light plane equation is fitted,the mathematical model of the line structured light system is constructed,and the conversion relationship between the light plane coordinate system and the world coordinate system is solved to complete the system calibration.
