摘要
Camera self-calibration methods use the image data only, and determine the camera model up to a similarity transformation. The absolute dual quadric based linear camera self-calibration method is often used to find an initial solution of the camera parameters due to its simplicity and effectiveness. According to the non-positive definiteness of dual image of absolute conic (DIAC), we introduce a semi-definite programming based self-calibration method. It constrains the semi positive definiteness and the validness of intrinsic parameters. The experimental results on both synthetic data and real images verify the effectiveness and robustness of the algorithm.
