Device and method for detecting lodging resistance of field rice stalks

Abstract

The invention relates to a field rice stalk lodging-resistant capability detection device which comprises a moving tool, and a first unmanned aerial vehicle, a second unmanned aerial vehicle and a remote host are carried on the moving tool; the remote host divides the test field into a plurality of sub-regions distributed in a matrix, and edits a set path according to the sub-regions so that the first unmanned aerial vehicle flies over each sub-region; the set path comprises a transverse moving path, the transverse moving path comprises a plurality of lifting nodes, a longitudinal moving path is arranged at the lifting nodes, and the first unmanned aerial vehicle resets to return to the lifting nodes after moving along the longitudinal moving path at the lifting nodes and continues to move along the transverse moving path; an image acquisition unit is carried on the second unmanned aerial vehicle; by means of the method, a complete test field can be tested in an extremely short time after simple setting, in addition, the inclination state of rice in the sub-region under different wind pressures can be obtained by adjusting the longitudinal height of the first unmanned aerial vehicle at the lifting node, and the detection flexibility is high.

Description

technical field [0001] The invention relates to the technical field of lodging resistance detection of rice stalks, and more particularly, to a detection device and a detection method for the lodging resistance of rice stalks in the field. Background technique [0002] The lodging resistance of rice roots and stems is an important indicator of rice. Rice lodging refers to the phenomenon that crops that grow upright are skewed in pieces due to natural factors such as wind, hail and rainstorm, or even the whole plant falls to the ground. When crops such as rice are seriously lodged, it will seriously affect the yield and may even cause no harvest; [0003] At present, the lodging resistance of rice roots and stems in experimental fields mostly needs to be checked manually, which is time-consuming and labor-intensive. Although the accuracy of individual detection can be guaranteed, there are usually large errors in the overall lodging resistance level of experimental fields. C...

[0003] At present, the lodging resistance of rice roots and stems in experimental fields mostly requires manual spot checks, which is time-consuming and labor-intensive. Although the accuracy of individual detection can be guaranteed, there are usually large errors in terms of the overall lodging resistance level of experimental fields, and detection It will damage the crops, and a device and method that can quickly detect the lodging resistance of rice stalks for the whole test field are needed
