Paper Abstract

According to the different degree distortion of lens array used in machine visual detection and high precision three-dimensional (3D) reconstruction, this paper proposes a combined radial and tangential distortion model-based for lens array distortion correction. A lens follows the pinhole model if and only if the projection of every line in space onto the lens is a line. In this paper, we propose straight lines fast correction algorithm to correct lens distortion to an estimated average error less than 1 pixel. In the algorithm, we adopt automatically detecting chessboard corners and linear interconnected algorithm to weaken human disturbance. Experimental results indicate that the algorithm can promote the precision and strengthen the robustness, meanwhile, greatly reduce the running time.
