This sample application performs a fisheye lens calibration using input images taken with the same camera/lens. Then it uses Remap and the calibration data to correct fisheye lens distortion of these images and save the result to disk. The mapping used for distortion correction is VPI_FISHEYE_EQUIDISTANT, which maps straight lines in the …
