Calibration of a 3D environmet scanner with a pair of line lasers

3D laser scanners are widely used systems to capture surface geometry. Conventional laser scanners have one laser source. In this study, a laser scanner systems with two laser sources is considered. The scanner is capable of minimizing the effect of occlusion in the scene. But the calibration issue becomes more complicated for scanners having more than one laser source. In our study the calibration problem of such scanners are defined. Some scene specific informations like orthogonalities, co-planarities are used for solving this problem.
