Robust 3-D reconstruction from single camera rotation stereo

We proposed a high accuracy measurement system for free shape objects using a single camera rotation stereo method. The aim is to allow inspection of small defects by a defect inspection system. Our proposed method measures the panoramic image of an object while rotating it, and estimates the 3D coordinate values (XYZ) from a single camera rotation system. Moreover, we apply an M-estimator which has a robustness for noise and solves the stereo correspondence problem under geometric constraints. Experimental results for real and simulation data show that the proposed method is effective as noise can be eliminated. The proposed method can also reconstruct objects.
