Three-dimensional human body posture and shape reconstruction method capable of shielding perception

According to a three-dimensional human body posture and shape reconstruction method oriented to shielded human body scenes, a human body model can be reconstructed from a shielded human body scene, so that a computer can understand and analyze the human body model conveniently, the human body model is not influenced by a picture scene, and an accurate human body model is reconstructed. The method provided by the invention comprises the following steps: step 1, generating a human body contour map of mutually shielded human bodies; step 2, coding human body joint points by using the human body contour map generated in the step 1 to serve as input data; step 3, obtaining human body model parameters by using a regression network composed of a ResNet encoder and a regression device; step 4, rendering and generating a pre-estimated human body contour and human body joint points by using pre-estimated human body parameters; step 5, comparing the pre-estimated human body contour and human body joint points with real
