Abstract: PURPOSE: An error correction method according to an incident angle of a distance measurement sensor is provided to more accurately measure a distance to a measurement object by correcting an error of distance measurement according to an incident angle when a light source of a distance measurement sensor meets a measurement object. CONSTITUTION: An error of measured distance according to an incident angle of a distance measurement sensor is statically calculated(S110). A distance from the distance measurement sensor to a measurement object is measured(S120). A distance of coordinates within a predetermined region of the measurement object through pan-tilt motion of the distance measurement sensor is calculated(S130). A plane vector PT of the surface of the measurement object is calculated utilizing the distance values of the measured predetermined coordinates(S140). An incident angle which a light source of the distance measurement sensor and the measurement object make using a formula is calculated(S150). A correction distance error is calculated according to the incident angle which the measurement object and a corrected distance dc is obtained by correcting the measured distance dm in the distance measurement sensor(S160).
