This invention discloses a stripe projection 3D imaging system based on a Micro-LED array. Its 3D information acquisition module consists of an integrated packaged Micro-LED driver board, a Micro-LED array, a micro-projection module, and a CCD camera. The 3D reconstruction module utilizes a computer. The micro-projection module is equipped with a plano-convex lens and a mechanical focusing damping structure, and is separately arranged in the front and rear optical paths of the Micro-LED array. The system's workflow is as follows: the driver board reads pre-stored stripe pattern data and timing-controls the Micro-LED array to output coded structured light stripes; the focusing structure adjusts the object distance in the optical path, focusing and scaling the stripes before projecting them onto the surface of the object being measured; the CCD camera simultaneously acquires a sequence of deformed images modulated by the object's shape and transmits it to the computer; the computer combines a multi-step phase-shifting algorithm and Gray code rules to complete phase calculation and unfolding, and, combined with a preset phase-height mapping relationship, reconstructs the 3D shape and point cloud data of the object being measured. This invention enables low-cost, miniaturized, and high-performance 3D shape measurement.
