A portable 3D vision coordinate measuring system using a light-pen is proposed. The system’s mathematical model, which is a particular case of Perspective of Three-Points-Problem (P3P), is established. Then, it is verified that the system’s model has a unique solution. Finally, the effectiveness of the model is confirmed by experiments.
