The proposed method can calibrate all the camera parameters from a single image.
We propose a DLT-lines based camera calibration method for experimental mechanics. Resultsīoth synthetic and real data are used to evaluate the performance of our method, which demonstrates that the proposed method can calibrate the cameras with radial and tangential distortions accurately. In the last step, a non-linear optimization algorithm is used to jointly refine all the camera parameters, including the distortion coefficients. The relationship between the distorted 2D lines and the distortion coefficients is derived, based on which the distortion coefficients can be solved linearly. Based on the DLT-Lines, the projection matrix is estimated linearly, and then the camera intrinsic and extrinsic parameters are extracted from the matrix. We parameterize the 3D lines with the intersection of two planes that allow the direct linear transformation of the lines(DLT-Lines).
#Camera lens distortion calibration full#
In this paper, we propose a full camera calibration method to estimate the camera parameters, including camera intrinsic parameters, extrinsic parameters and lens distortion parameters, from a single image with six or more non-coplanar lines.
Most plumb line methods focus on solving lens distortions without considering camera intrinsic and extrinsic parameters. Camera calibration is an essential step for the optical measurement method used in the experimental mechanics.
