The invention provides a fixed-wing oblique photography cadastral mapping method, system and equipment. The system comprises a mapping device, the device comprises an unmanned aerial vehicle and an oblique photography camera, and the method comprises the following steps: arranging a target; collecting image data through aerial photography; acquiring a calculation result, performing live-action modeling based on the calculation result to generate a live-action three-dimensional image, and measuring height, length, area and width to obtain three-dimensional data; acquiring a live-action three-dimensional image from different angles such as a vertical angle and an inclined angle to form an inclined model and obtain vector data; and obtaining mapping data based on the stereo data and the vector data. According to the invention, the fixed-wing unmanned aerial vehicle oblique photography technology is utilized to obtain the high-definition stereoscopic image data, and the live-action three-dimensional model is generated according to the encrypted point data to carry out cadastral mapping, so that the defects of the rotor unmanned aerial vehicle are effectively overcome, the form of the live-action is truly reduced, the field manpower and material resources are greatly reduced, the time is saved, the working efficiency is improved, and meanwhile, the mapping quality and precision can be improved.
