The invention discloses a live-action three-dimensional model construction method and device, electronic equipment and a storage medium, and the method comprises the steps: generating a triangulation network terrain three-dimensional curved surface of a to-be-constructed target through digital elevation data, and carrying out the geometric correction of the curved surface, the corrected curved surface is used for performing geometric structure reconstruction on the initial three-dimensional live-action model obtained based on the point cloud reverse modeling technology, so that the method is equivalent to using the point cloud reverse modeling technology and the geometric terrain curved surface correction technology to construct the live-action three-dimensional model with high spatial precision, and therefore, the method can be used for constructing the three-dimensional live-action model with high spatial precision. According to the method, the problem of ribbon loopholes or independent loopholes existing i
