Abstract
In order to calculate an actual distance between coordinates in an image, a regular image for an original image may be generated based on an intrinsic parameter of a camera and pose information of the camera, based on first coordinates in the regular image that are received, first world coordinates corresponding to the first coordinates may be calculated in a world coordinate system, based on second coordinates in the regular image that are received, second world coordinates corresponding to the second coordinates may be calculated in the world coordinate system, and a distance between the first world coordinates and the second coordinates may be calculated.
