A research on adaptive calibration algorithm for multi-geometric projection

Abstract

To realize the adaptive projection of the projector on a variety of common projection planes and improve the efficiency of geometric correction, a multi-geometric function for adaptive correction algorithm is proposed. It uses the feature points to automatically fit out the curvilinear function. By automatically filtering the function corresponding to the pixel mapping relationship and calculating the projection pixel offset, the projection screen is cut according to the degree of correction, and finally the coordinates of the vertex are corrected by cutting the texture relationship to achieve geometric correction. The experimental results show that the proposed algorithm can achieve the practical application value of geometric distortion correction, such as cylindrical surface, spherical surface, common surface and projector non — projection, simply and quickly.
