Abstract

The invention provides a parcel survey system and method based on an unmanned aerial vehicle. The system comprises the unmanned aerial vehicle, a user terminal and a remote control signal transmitter,a flight control system, a front information acquisition unit, a ground information acquisition unit, a positioning module, a first data transmission module, a first image transmission module and a remote control signal receiver are arranged on the unmanned aerial vehicle, the front information acquisition unit, the ground information acquisition unit, the positioning module, the first data transmission module, the first image transmission module and the remote control signal receiver are connected with the flight control system, the remote control signal transmitter is connected with the remote control signal receiver, the user terminal is provided with a measurement and control system, a second data transmission module, a second image transmission module and an image display module, thesecond data transmission module, the second image transmission module and the image display module are connected with the measurement and control system, the image display module is connected with the measurement and control system, and the second data transmission module and the second image transmission module are connected with the first data transmission module and the first image transmission module. The unmanned aerial vehicle for survey replaces manual labor of people, and survey speed is increased. The ground information acquisition unit and the front information acquisition unit areadded to the unmanned aerial vehicle, lower and front view fields of the unmanned aerial vehicle can be simultaneously observed, parcel edges are accurately measured, protection forests can be recognized, and self-security is ensured.

Description

Technical field [0001] The invention relates to the field of agricultural technology, in particular to a land plot measurement system and method based on drones. Background technique [0002] The traditional measurement of rural plots generally uses methods such as measurement and step size. For some plots with irregular shapes, the area is calculated by filling and cutting, so there is a large error in the area. [0003] With the development of modern global positioning systems, acre measuring instruments using GPS and other technologies have replaced traditional measurement methods. The handheld acre measuring instrument is an instrument that uses a global positioning system (GPS, Beidou, Galileo, etc.) to collect the latitude and longitude coordinates of the edge points of the plot to obtain the shape of the plot and use the mathematical method to calculate the plot area. As a measuring tool, the acre meter is suitable for measuring the area of ​​farmland, green space, forest, ...

AI Technical Summary

Problems solved by technology

Disadvantages: If you deviate from the route, you cannot correct the deviated route, resulting in deviations in the shape and area of ​​the measured plots

[0007] Traditional agricultural surveying only gives an approximate area by measurement and other methods, which is not accurate enough, and there is no more detailed land shape and location data
