Real-time three-dimensional geographical mapping system for unmanned aerial vehicle

Abstract

The invention discloses a real-time three-dimensional geographical mapping system for an unmanned aerial vehicle. The system comprises a ground station interaction system, a photographing system, a velocity / acceleration sensor, a GPS, an angular velocity / acceleration sensor, motor driving, cloud deck control and a high-speed data transmission channel. The ground station interaction system communicates with a ground station through a wireless network, and data are transmitted through the high speed data transmission channel between the ground station and the unmanned aerial vehicle. By route planning on a to-be-tested region, image and position information is collected automatically in real time; and furthermore, the ground station can operate and construct a three-dimensional geographical information map in real time through a real-time transmission system.

Description

technical field [0001] The invention relates to a real-time three-dimensional geographic surveying and mapping system for an unmanned aerial vehicle. Background technique [0002] With the needs of digital city construction, security, and forest fire prevention, it is necessary to construct a three-dimensional geographic information map through aerial photography. Due to the advantages of lightness and flexibility, strong programming ability, and low environmental requirements, drones can take off at any time when needed. The existing three-dimensional geographic information rendering requires professional personnel with low-altitude flight qualifications, aircraft on duty, and data collection through complex recording and camera equipment. [0003] The whole process has high requirements on personnel and weather conditions; moreover, due to more human-computer interaction, there are many uncertain factors, the acquisition accuracy is poor, and the real-time performance is ...

The existing three-dimensional geographic information rendering requires professional personnel with low-altitude flight qualifications, aircraft on duty, and data collection through complex recording and camera equipment

[0003] The whole process has high requirements on personnel and weather conditions; and due to more human-computer interaction, there are many uncertain factors, poor acquisition accuracy and poor real-time performance

[0004] Furthermore, this kind of drawing method often needs to collect first and then process it. For some specific scenarios and emergencies that require real-time construction of the system, it cannot meet the application requirements
