The measure method of information quantity for terrestrial laser scanner (TLS) 3D point cloud data have seldom been studied in previous publications. In this paper, we mainly discuss how to measure information quantity of point cloud data. We give the procedure of measuring information quantity for point cloud, and obtain the formula of calculation. Furthermore, we calculate the information quantity of 5 types of point cloud data, which verified the feasibility of the information measure theory for point cloud.
