An aircraft-based building measurement method, system, terminal and medium

Abstract

The present application relates to an aircraft-based building measurement method, which includes the following steps: controlling the preset aircraft to reach the estimated building height; measuring whether the current level of the aircraft overlaps with the building, and controlling the aircraft to rise until the aircraft is at the level Obtain and generate a calibrated height based on the current height of the aircraft until the overall height is higher than the measured building; control the aircraft to take the center coordinate point as the center of the circle, and use the estimated building width as the cruise radius to perform circular motion; determine the cruise track and measure in real time when the aircraft is cruising The vertical distance of the aircraft from the ground determines the cruise track of the aircraft; scans the top of the building to generate point cloud data on the top of the building; controls the aircraft to lower its height, runs according to the cruise track, takes the centripetal direction as the measurement direction, and scans the side of the building at a set frequency; Generate a 3D model of the measured building. This application has the effect of improving the efficiency of field measurement.

Description

technical field [0001] The present application relates to the field of building surveying and mapping, and in particular to an aircraft-based building surveying method, system, terminal and medium. Background technique [0002] At present, the field measurement of the facade is mainly to measure the distance and height difference between the points on the facade of the house through the side-to-side measurement function of the prism-free total station, draw a sketch of the facade of the house, and record the measured data , to mark the length on the sketch. The office surveying and mapping is mainly to re-input the collected data into the computer. The calculation of the facade area is mainly carried out by CAD software. The area of ​​each facade is calculated by using the area marking function of the software, and then the area of ​​each facade is accumulated. It is easy to make mistakes when calculating. Since the entire data processing process has many procedures and is...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there is a defect that the current field survey requires manual handling of the total station for positioning detection and transcription of measurement data, resulting in low efficiency
