Embodiment Construction

[0035] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] As shown in Figure 1. The present invention comprises six parts structurally: off-road vehicle 1, small ultra-low-altitude unmanned aerial vehicle 2, automatic navigation control system 3, camera 4, communication system 5, and signal processing system 6. Wherein the camera 4, the automatic navigation control system 3, and a part of the communication system 5 are installed on the support at the bottom of the small aircraft 2; the signal processing system 6 is mainly composed of a computer and automatic recognition software for locust images. The off-road vehicle 1 is used both for loading measurement equipment and as a ground station.

[0037] The unmanned aerial vehicle 2 is a general-purpose model: such as: YAMAHA RMAX aerial robot produced by Japan's Yamaha Motor Co., Ltd. (YAMAHA MOTOR); RPH2 developed by Japan's Fuji Heavy ...

Abstract

The invention relates to locust plague minimum altitude early-warning system and field locust automatic identification method. It includes cross-country car, unmanned vehicle, auto navigation control system, video camera or camera, communication system, and signal processing system. The method includes the following steps: real time or fixed point taking ground locust image respectively by digital video camera or camera fixed on vehicle bottom bracket; transmitting the image information to the signal processing computer by communication system or DV tape; processing and analyzing the input image by computer.

Description

technical field [0001] The invention relates to the field of electrification and automation in precision agriculture, in particular to an ultra-low-altitude early warning system for locust disasters. The invention also relates to a method for automatic identification of locusts in the field. Background technique [0002] The locust plague is a devastating biological disaster, and together with floods and droughts, it constitutes the three natural disasters of human society. Since the mid-1980s, due to the influence of abnormal climate and changes in the agricultural ecological environment, new locust areas have continuously emerged in various parts of my country, and old locust areas have repeatedly appeared. The frequency of locust occurrences has increased and the degree of damage has increased. According to preliminary statistics, my country's migratory locust occurrence areas currently involve 16 provinces and municipalities, with an occurrence area of ​​more than 200 m...
