A three-dimensional information generating method, comprising: Projecting a movable scanning beam to an object to be tested, the scanning beam having a specific pattern with incomplete repetitive pattern information; sensing an image of the object to be tested to generate two-dimensional image information; The reflected light of the object to be tested is generated by a triangulation method according to the image of the specific pattern, and the distance information is integrated with the two-dimensional image information to generate three-dimensional information related to the object to be tested; and sensing The color, sound, density, or level of the object to be tested, and the three-dimensional information forms a three-dimensional object information.
