Abstract

We present herein a technique to calibrate fisheye lenses using cross diffractive optical elements. The setup generated a robust and accurate virtual calibration grid, and the calibration was performed by rotating the camera around two axes. We propose a comparison of three fisheye mathematical models and an evaluation of the number of images in the calibration process. The comparison of our experimental data according to the 3D calibration object results showed that our technique is efficient and reliable.
