Abstract:
1. An image processing method of obtaining image data undergoing a distortion correction process by using plural pieces of pixel data acquired when an image capturing element including a plurality of pixels receives the light via an optical system including a lens, the method comprising: a first step of setting a position and a size of a datum plane always having a fixed positional relationship with, a virtual, projection plane in a world coordinate system on the basis of a user's instruction; a second step of calculating coordinates of the respective pixels on the virtual projection plane in the world coordinate system on the basis of the datum plane set in the first step, and converting the calculated coordinates into a camera coordinate system by using a distortion correction coefficient of the optical system; a third step of calculating the image data on the virtual projection plane on the basis of the plural pieces of pixel data and the coordinates in the camera coordinate system with the conversion being done in the second step, wherein datum plane system coordinates x the second step includes calculating the coordinates of the respective pixels on the virtual projection plane in the world coordinate system on the basis of the two-dimensional LUT by an image processing unit.
