For the laser tracking measurement task ,the result of measurement field planning is very important.The layout planning method based on laser vision sensing is designed to meet the practical application requirements.Based on laser vision sensing technology ,a laser vision sensor is designed ,which is composed of a camera ,a filter and a laser ,and is used to collect the image of the measuring field. For the collected image ,the adaptive median filter is used to de-noise it. The layout planning algorithm of the application planning engine and CAM2 is designed. In many iterations ,the particle swarm optimization algorithm is used to solve the problem ,and the layout planning of the meas- urement field is realized through this algorithm. The test results show that the layout planning results of the two stations in the design method are complementary ,indicating that the layout planning can complete the measurement task and the planning results are effective.
