%X In low cost cameras and widcangle cameras, lens distortion should be calibrated. In traditional methods, camera's interior parameters and lens distortion are calibrated together. In this work,we presented a method to calibrate distortion and camera's parameters, without any calibration objects and 3D coordinates. Lens distortion was corrected based on the projective invariant of straight lines,orthogonal straight lines were used to calibrate camera's interior parameters. The accuracy and availability of the method were verified on the experimental result of simulation and real data.
