Abstract: The building elevation is the basic data of the facade lighting design, which directly affects the design accuracy and effects. Aiming at the problems of low efficiency and low reduction degree on traditional facade measurement, a building facade measurement scheme based on 3D laser scanning technology is proposed. Combined with the actual case, the method of traversing 3D laser scanning and point cloud drawing is mainly discussed. The application case shows that 3D scanning technology can provide accurate and detailed building elevations for facade lighting design.

Key words: lighting design, building facade measurement, traversing 3D laser scanning, point cloud drawing, SX10
