Multi-view three-dimensional reconstruction method and system

The invention relates to the technical field of computer vision, and provides a multi-view three-dimensional reconstruction method and system, and the method comprises the steps: constructing a first cost body of a three-dimensional matrix according to an obtained to-be-processed image, and calculating a weight parameter of a feature channel according to a depth vector of the three-dimensional matrix, acting the weight parameter on the first cost body to generate a first probability body; filtering the first probability body to obtain a second probability body; acquiring a real depth map according to the to-be-processed image and constructing a third probability body; a learning model obtained through training of a loss function is obtained to generate a real probability body, the loss function is generated according to the second probability body and the third probability body, a prediction depth map is generated according to the real probability body, and a global point cloud representing completion of mult
