Abstract
A method implemented by a computer of calculating a distortion correction coefficient, the method including: extracting a plurality of line segments by executing a line segment extraction process on each of a plurality of captured images that have different imaging times; and calculating an optimal value of the distortion correction coefficient, the calculating of the optimal value including: executing, for each line segment of the plurality of line segments, a distortion correction process on the each line segment while changing a setting value of the distortion correction coefficient, and evaluating a processing result obtained by the executing of the distortion correction process.
