A New Approach for Handheld and Multi-Angle Structured Light Measurement

The approach for structure light 3D measurement is widely used in many fields. Objects are measured by immobile cameras and lasers in some traditional methods, so it isn’t portable and flexible. Then this paper proposes a handheld and multi-angle approach for measuring objects. The new approach is different from traditional methods. It doesn’t require sophisticated mechanically-driven system, and it could meet the measuring requirement in the different perspectives of objects. A laser and a camera are only used to complete measurement to objects. So the measurement system cost is lower. In addition, the laser and camera can be taken with hands to measure objects, so it is more convenient and quick. Through theoretical analysis, the measurement results can be greatly improved. Preliminary experimental results verify that  it is portable and fast, and it  can complete measurement in the different perspectives of objects. So the novel approach is feasible.
