摘要： Disclosed is a method of detecting and correcting an error in a 3D mesh model. According to the present disclosure, the method includes: determining at least one mesh on the basis of half-edge information; setting at least one cluster including the at least one mesh, on the basis of normal vector information on the at least one mesh; detecting a flip error of the at least one cluster; and correcting the at least one mesh in the at least one cluster in which the flip error is detected.
