Abstract
An image calibration method according to the present invention includes the steps of receiving a calibration request from a user terminal(S), receiving a calibration object image photographed in accordance with an instruction for calibration photographing (S), performing a calibration process using the received calibration object image (S), receiving a subject image photographed by a camera, transmitted from the user terminal(S), performing a calibration on the subject image in accordance with results of the calibration process to form a corrected subject image (S), and returning the formed corrected subject image to the user terminal(S). The present invention allows acquisition of a corrected subject image in which distortions due to the camera lens are corrected even for those unskilled in three-dimensional measurement based on the principle of the stereo method, precise two-dimensional measurement, and precise image formation.
