A Geometric Correction Method Based on Pixel Spatial Transformation

Abstract

To achieve the non-planar projection geometric correction, this paper proposes a geometric correction method based on pixel spatial transformation for non-planar projection. The pixel spatial transformation relationship between the distorted image on the non-planar projection plane and the original projection image is derived, the pre-distorted image corresponding to the projection surface is obtained, and the optimal view position is determined to complete the geometric correction. The experimental results show that this method can achieve geometric correction of projective plane as cylinder plane and spherical column plane, and can present the effect of visual distortion free at the optimal view point.
