| Abstract(in English) | To calibrate radially symmetric distortion of pinhole camera and/or omnidirectional cameras such as fish-eye lenses, calibration parameters are usually estimated so that lines, which are suppored to be straight in the real-world, are mapped to straight lines in the calibrated image. In this paper, this problem is treated as a fitting problem of principle curves in uncalibrated images in the framework of kernel principle component analysis, and an estimation procedure of calibration parameters is proposed based on Jacobian kernel principle component analysis. |
