Based on the principle of laser triangulation,the influencing factors of laser on-machine measurement accuracy are analyzed;the conformal mapping algorithm is used to convert the three-dimensional model of complex curved surface to two-dimensional plane,and the laser on-machine measurement path is planned;combined with the directed bounding box algorithm,the scanning attitude of the sensor is controlled,the measurement accuracy and efficiency are improved,and the laser on-machine measurement path is optimized.The experiment of line laser on-machine measurement complex curved surface is carried out,the results show that compared with the existing measurement strategies,the accuracy and efficiency of the optimized laser on-machine measurement are significantly improved.
