[0032] The present invention will be further described below with reference to the accompanying drawings and the specific embodiments of the present invention.
[0033] The present invention is a method for reconstructing a virtual scene light source based on a single night scene image of a building. The input is a 3D model of the building and its corresponding real night scene image, and the output is a set of light source parameters, so that the 3D model corresponding to the building is under the action of the group of light sources. renders similar to the input image.
[0034] The entire reconstruction method includes the following steps: figure 1 shown;
[0035] Step (1) is the estimation of camera parameters. like figure 2 A set of matching points is selected on the model surface and in the input image using the given graphical interface. According to the matching relationship, a set of linear equations are established to estimate the camera internal parameters (foca...
