Method for synthesizing 3D face model by using optical reflection

Abstract

The invention relates to a method for synthesizing a 3D human face model by using optical reflection, and the method comprises the steps: obtaining a plurality of human face three-dimensional images and RGB color images at a plurality of angles relative to a front face from an optical reflector through rotating a 3D structured light rotation module, wherein the optical reflector respectively corresponds to the obtaining positions of the human face three-dimensional images at all angles; generating a point cloud image and a color map corresponding to each angle according to the face three-dimensional image and the RGB color image; synthesizing the corresponding point cloud images in the two face three-dimensional images with the minimum absolute value of the angle relative to the front face into a first synthesized image; synthesizing the corresponding point cloud images in the face three-dimensional images of the remaining angles with the first synthesis image in sequence; and rendering the synthesized image according to the color map to obtain a 3D face model. The method has the advantages that the image precision is high, more accurate face depth information can be obtained, and a good reference is provided for medical and aesthetic plastic surgery.

Description

technical field [0001] The invention relates to a method for synthesizing a 3D human face model, in particular to a method for synthesizing a 3D human face model by using optical reflection. Background technique [0002] With the continuous progress of the times and society, people are paying more and more attention to their own skin and other appearance characteristics, so the need to know the state of their skin is becoming stronger and stronger. In the fields of medical cosmetology, such as skin care product recommendation, skin quality analysis, etc., people usually need to conduct certain detection and analysis of the skin condition of the whole face, and then formulate corresponding strategies based on the analysis results. By using analytical instruments to test the skin, recommend appropriate skin care products through the test results, or formulate corresponding skin care strategies. Among them, the skin detector is an instrument used to detect skin. It is equipped...

[0003] However, current skin detectors usually only shoot with a single camera, or take pictures of faces by rotating the device. The former can only take facial images from one angle at a time. If you need to take facial images from different angles, you need to artificially rotate your head and shoot The formed picture is basically a two-dimensional graphic, the image cannot be rotated three-dimensionally, and the contour analysis is not accurate, and the latter is extremely expensive and expensive
