Abstract
A method for determining a fisheye camera shadow correction parameter, comprising: capturing and acquiring a raw image using a fisheye camera that is not installed in an outer housing; obtaining the raw image from the fisheye camera; performing statistics on luminance information and chrominance information in each block of the raw image; and calculating a correction parameter for the fisheye camera based on the luminance information and the chrominance information of each block.
