Abstract: The multi-angle large-field-depth high-precision 3D visual sensing technology is proposed, which uses the high-definition digital light processing (DLP) structure light projection technology and high-speed high-resolution industrial camera to conduct in-depth research on board-level integrated circuit design, control drive software R&D, and 3D point cloud reconstruction and processing algorithms, and independently develops sub-micron-level/low-cost high-precision 3D visual measurement technology. High-resolution and high-frame-rate industrial cameras are used to achieve high-precision 3D reconstruction. The multi-wavelength phase spread method is used to implement high-precision phase calculation. Multi-industrial cameras are used to hide the field of view, expanding the three-dimensional reconstruction of the field of view, and finally achieving the repetition accuracy of the 0.48 μ m Z axis.

Keywords: multi-perspective; three-dimensional reconstruction; multi-wavelength phase spread method
