Abstract

In this paper, we propose a non-contact real-time centroid measurement method for non-cooperative targets, which calculates the coordinates of the centroid point of the motion model in real time at a frequency of 30 Hz. The TOF (Time of flight) camera configuration, working principle and point cloud preprocessing technology including point cloud fusion of the measurement system are presented. Through the XYZ coordinates of the point cloud data, we calculate the centroid point position of the model. Experiments show that the measured centroid point XYZ three-axis accuracy is about 0.1mm.
