The present invention relates to a method for detecting the texture, geometric shape and geometric center of a geometric element, which comprises the following steps: providing a first light beam projected on the object under test to obtain a gradual gradient image, and its texture and topography are reconstructed; providing a second light beam directed toward the object, and then the object is rotated, to obtain a continuous surface shape track, and reconstructs the surface shape of the object; calculating the geometric center from the surface shape track, and superimposes the surface shape track with the topography to rebuild a three-dimensional geometric contour of the object.
