A data acquisition system based on UAV

Abstract

The invention relates to a data acquisition system based on an unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicle surveying and mapping. The cycle time for surveying and mapping is shortened. The data acquisition system based on the unmanned aerial vehicle includes a ground system and an unmanned aerial vehicle with a camera, and the unmanned aerial vehicle includes: a main controller, a vibration sensor and a wind speed sensor, which are used to detect the wind speed at the location of the unmanned aerial vehicle, and Send the wind speed data to the main controller; when the main controller judges according to the vibration data whether the time ratio of the vibration amplitude of the UAV in the preset time exceeds the preset vibration threshold exceeds the ratio limit value 1, when the vibration amplitude exceeds the preset When the vibration threshold is set, the UAV stops shooting and hovers at the preset height. After the UAV hovers, the main controller judges whether the time ratio of the wind speed data exceeding the wind speed threshold within the preset time 2 exceeds the ratio limit 2. If so , the drone lands on the ground, if not, the drone arrives at the destination or returns to the starting point along the flight route.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle surveying and mapping, in particular to a data acquisition system based on an unmanned aerial vehicle. Background technique [0002] The UAV aerial survey and remote sensing system can perfectly realize its own value in various industries, and can promote the development of each industry, mainly because it has high practicability, such as the application in surveying and mapping, which solves the problem of There are many technical and environmental problems in surveying and mapping. There are also unique innovations and superior backbone systems. UAVs have played an irreplaceable role in the construction of new countryside, the construction of digital cities, and so on. It can be applied to low-altitude UAV surveying, mapping, surveying and remote sensing systems in many fields, such as some large-scale projects, planning of new cities, responding to various emergencies, and spee...

AI Technical Summary

Problems solved by technology

[0003] For aerial photography equipment, wind speed is a big factor, because the greater the wind speed, the poorer the effect of aerial photography, and the clarity of pictures recorded by aerial photography equipment is blurrier than when the wind speed is slow.

When the aerial photography equipment is performing aerial photography tasks, the wind speed of a section of the flight route may be too high to cause the pictures of this section of the route to be collected again. This problem is often found when the pictures are checked after the mission is over, and then the aerial photography task needs to be carried out again , Delayed the entire cycle of surveying and mapping
