[0037] specific implementation plan
[0038] The present invention will be further described in detail below in conjunction with the examples and drawings, but the implementation of the present invention is not limited to this example.
[0039] The dynamic paddy field flatness detection device based on laser distance measurement includes a laser distance meter, a connecting bracket and a PC. The laser range finder is installed behind the farmland operation vehicle through a connecting bracket, scans the field vertically, and dynamically collects data points on the field surface when the farmland operation vehicle is driving. The laser rangefinder is connected to the PC through the RS232 interface, and communicates with the PC in real time during actual measurement. The PC uses Matlab software to read the measurement data of the laser rangefinder and process the data. The data processing of the PC includes coordinate conversion of measurement data, threshold filtering and thr...
