Problems solved by technology

Real estate survey is a kind of cadastral survey, which requires high precision. The traditional survey method is to use the combination of total station and RTK, which is labor-intensive and heavy workload. After a lot of testing and engineering verification, the project cycle is long and the efficiency is low.

Abstract

The invention discloses a high-precision real estate measurement method based on a multi-rotor unmanned aerial vehicle. The method comprises the following steps: 1, a multi-rotor unmanned aerial vehicle high-precision real estate measurement device is constructed; 2, photo control points are arranged and the geographic coordinates of the photo control points are obtained; 3, route planning is carried out; 4, data acquisition is carried out; 5, data processing is carried out; 6, a live three-dimensional model for a to-be-measured real estate measurement area is established; 7, mapping is carried out; and 8, precision check is carried out. The multi-rotor unmanned aerial vehicle is used to carry an oblique camera and a vertical camera to acquire high-definition three-dimensional image data,the live three-dimensional model is generated, naked-eye three-dimensional mapping is carried out in the live three-dimensional model, the real estate geographic information is rapidly obtained, the labor intensity and the workload of operators are greatly reduced, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of real estate measurement, and in particular relates to a high-precision real estate measurement method based on a multi-rotor drone. Background technique [0002] UAV aerial photogrammetry is a high-tech developed in recent years. It subverts the limitation that the previous orthophoto can only be taken from a vertical angle. Capture images from different angles, introducing users to a real and intuitive world that conforms to human vision. UAVs have the advantages of fast response, high processing efficiency, and low operating costs. The combination of the two has subverted the traditional surveying and mapping operation method, and the high-definition stereoscopic image data can be obtained through low-altitude multi-lens photography of UAVs, which can quickly realize geographic information. Acquisition has the characteristics of high efficiency, low cost, accurate data, flexible operation, rich side in...
