Abstract: In order to improve the development level of rubber-tyred vehicle (RV) and reduce the manpower and material resources in its development， a new development method of RV based on 3D camera scanner is studied and designed. Through the Focus 350 3D scanner and other hardware， the point cloud data on the upper part of the RV cab is obtained， and the point cloud data of different positions and different cameras are connected， filtered， simplified and interpolated by the Geographic Studio software. The surface reconstruction on the upper part of the RV cab is completed by CATIA software， and the evaluation method for the smoothness of the surface reconstruction is established. It is concluded that the maximum curvature change of the surface model of the upper cab is 0.012 mm-1 and the minimum is -0.838 mm-1. Finally， through the above research methods， the whole vehicle is developed and manufactured. This research can provide theoretical reference and basis for the independent research and development of RV in China.
