Embodiment 1

[0053] Embodiment 1 of the present invention provides a system for assessing the growth of crops in the field, the composition diagram is as follows figure 1 shown, including:

[0054]The field operation machine 10 and the remote management terminal 20, the field operation machine 10 collects crop canopy images in the field, obtains the angle value measured by the angle sensor and the latitude and longitude value of the positioning of the working area, and stores the crop canopy image, angle value and latitude and longitude value The value is sent to the remote management terminal 20. Among them, the size of the angle value is related to the hardness of crop stalks and crop density.

[0055] The remote management terminal 20 stores and processes the received crop canopy images, angle values, and latitude and longitude values ​​to obtain an operation instruction for the field operation machine, and sends the operation instruction to the field operation machine 10 .

Abstract

The invention discloses a system for estimating growth conditions of field crops. The system comprises a field working machine and a remote management terminal, wherein the field working machine is used for collecting a crop canopy image in a field, so as to obtain an angle value measured by an angle sensor, and longitude and latitude values for positioning a working region; sending the crop canopy image, the angle value and the longitude and latitude values to the remote management terminal, wherein the angle value is related to the value of the hardness of crop straws and the value of the density of the crops; storing and processing the received crop canopy image, angle value and longitude and latitude values by the remote management terminal to obtain an operation instruction of the field working machine; sending the operation instruction to the field working machine. The invention further provides a method for estimating the growth conditions of the field crops; in the method, data including gravity, bending acting force of a connection rod, horizontal acceleration, the crop canopy image and the like are comprehensively adopted; under the condition of not damaging the crops, the continuous and accurate measurement on the straw hardness and the plant density of the crops can be realized without manual operation, and a crop growth condition picture is drawn.

Description

technical field [0001] The invention relates to the field of field crop monitoring, in particular to a system and method for field crop growth assessment. Background technique [0002] The thickness of crop straw and the number of seedlings per unit area are two components of field crop growth indicators, which directly reflect the dry matter content per unit area of ​​the field, and are important reference indicators for germplasm selection in breeding and variable fertilization prescription generation in precision agriculture. How to realize the measurement of these two parameters accurately, effectively and quickly is particularly important. At present, there are many measurement systems and products for crop straw strength at home and abroad, but there are few devices for measuring the number of seedlings per unit area. There are fewer systems and methods for simultaneous determination of both. [0003] In terms of products, the typical straw strength tester (DIK-7400)...
