Problems solved by technology
The current equipment used in the medical aesthetics industry is all two-dimensional photo information, which cannot accurately represent the three-dimensional structure of the face, and cannot provide an intuitive display for preoperative analysis and postoperative effect simulation of plastic surgery
In addition, a large number of physical stores in the medical beauty industry are small in size, and the ability to equip large-scale medical beauty analysis equipment is insufficient, mainly reflected in the lack of enough space for placement, and the high level of operational skills required for users

The invention belongs to the field of three-dimensional machine vision, and relates to a compact high-precision three-dimensional face imaging method, comprising an optical module, an RGB-D depth camera, a fill light module and a posture corrector; The D depth camera is calibrated with four total reflection mirror systems; step 2, fix the human chin on the posture corrector to ensure that the face is still; step 3, point cloud registration; step 4, texture mapping. By rotating the platform, the number of RGB‑D depth cameras used is limited to one, which greatly reduces the equipment cost; the 10 standard ball system is used as the calibration benchmark, and the calibration accuracy for the four optical path systems is improved to 0.01mm; Cloud registration and texture fusion technology output a complete 3D face model.
Description
technical field [0001] The invention belongs to the field of three-dimensional machine vision, and relates to a compact high-precision three-dimensional face imaging method. Background technique [0002] Facial information is the core information of the medical beauty industry, and plays a vital role in the diagnosis and operation of medical beauty doctors. At present, the equipment used in the medical beauty industry is only two-dimensional photo information, which cannot accurately represent the three-dimensional structure of the face, and cannot provide an intuitive display for preoperative analysis and postoperative effect simulation of plastic surgery. In addition, a large number of brick-and-mortar stores in the medical aesthetics industry are small in size, and the equipment for large-scale medical aesthetics analysis equipment is insufficient, mainly because there is not enough space for placement, and the user's operating skills are required to be high. Therefore, ...
