Sealed connection judgment system for three-dimensional scene structure reconstruction and three-dimensional human body identity re-recognition

The invention discloses a close connection judgment system for three-dimensional scene structure reconstruction and three-dimensional human body identity re-identification. The close connection judgment system comprises the following steps: selecting positive patients; obtaining a three-dimensional human body model of a positive patient; performing pedestrian detection and masking on the video through a target detection neural network, and performing three-dimensional reconstruction by using a three-dimensional reconstruction neural network to generate a three-dimensional pedestrian pre-model; performing three-dimensional reconstruction on the whole video scene; and carrying out matching calculation on the pedestrian three-dimensional model and the positive patient three-dimensional model by using a ternary loss function neural network. Three-dimensional scene reconstruction is carried out by adopting the video stream, the correlation between adjacent frames of the video is fully utilized, and distance misjud
