Camera Correction and Matching in 3D Measurement of Raster Projection System

On the basis of projective theory, a mathematic modeling of camera imaging is built up for 3D measurement of raster projection system. The relationship between objects and their images is derived. A new method, non-separated parameters, is proposed for the intrinsic and extrinsic parameter calculation. Using this method, the complexity of nonlinear function solution is reduced and the system runtime is speedup. The bias of the two cameras is reduced, and the precision of 3D measurement are improved. Experiments of camera correction and matching are carried out in the raster projection 3D measurement. Satisfactory results have been obtained. It is proved that method has the advantages of easy operation, good stability and high precision.
