The acquisition of point cloud data from a space frame using terrestrial laser scanning is usually affected by many occluding components and site conditions and therefore needs to achieve optimal priori planning, which is handled as the planning for scanning (P4S) problem. This paper describes a three-dimensional model-based P4S approach for space frame structures, where a space modeling solution is employed to simulate the scanning target and environment. The P4S problem modeling is used to define the visibility analysis and constraints. Lastly, a two-phase optimization is proposed to solve the P4S problem and compared with a weighted greedy algorithm. Experiments were conducted on a full-scale space frame to validate the proposed approach.
