Three-dimensional modeling method based on inclination model and laser point cloud data fusion

The invention provides a three-dimensional modeling method based on fusion of a tilt model and laser point cloud data. The method comprises the following steps: acquiring tilt photogrammetry data, laser point cloud data and a panoramic photo; generating a three-dimensional model of oblique photography based on oblique photography measurement data; generating a final map template based on the laser point cloud data; carrying out fine registration correction on the three-dimensional model subjected to oblique photography and the final map template so as to enable the three-dimensional model and the final map template to be tightly attached together; respectively extracting respective advantage data from the panoramic photo and the matched three-dimensional model and final map template of the oblique photography according to each element, and generating a plurality of element models; and combining the plurality of element models based on the actual geographic positions of the plurality of element models to gener
