Method for correcting three-dimensional human body model based on 2D human body image

The invention discloses a method for correcting a three-dimensional human body model based on a 2D human body image, and relates to the field of human body three-dimensional correction. The method comprises the following steps: detecting first human body key points of an RGBD human body image; performing three-dimensional reduction reconstruction on the RGBD human body image to obtain a 3D human body model; performing front projection on the 3D human body model to obtain a 2D projection image; detecting second human body key points of the 2D projection image; corresponding the first human bodykey points to the second human body key points; correcting the distance between the second human body key points according to the distance between the first human body key points to obtain a 3D restored image fused with the 2D image information; and according to the second human body key points adjusted on the 3D restored image, mapping the 3D restored image back to the 3D human body model to complete adjustment of the 3
