Embodiment Construction

[0042] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] When the present invention is implemented, at first, adopt Lab space to carry out grayscale to image to a component under the condition of dynamic illumination weaker, adopt RGB color space 2G-R-B to grayscale to image under dynamic illumination sufficient condition; To grayscale The final image is binarized by the method of iteratively seeking the optimal threshold value, and then the noise points in the image are eliminated by median filtering; the center line of the image is fitted by the least square method, and finally the Hough transform is used to obtain navigation path.

[0044] Implementation steps of the present invention are as follows:

[0045] 1. Eliminate non-target ridges

[0046] The method to eliminate the non-target ridges is to find the position of the boundary column between the target ridge and the non-tar...

Abstract

The invention relates to a method of identifying the navigation path of the cotton field spraying machine, which used the machine vision system for collecting the images and computer for processing the digital image, the steps include: 1) eliminating the non-target ridge; 2) identifying the target location ridge boundary; 3) acquiring the centerline of ridge; 4) acquiring the navigation path: average the acquired the ridge centerline to get the navigation discrete points, then through Hough (Hough) transform to obtain the navigation path. The invention can be realized the spraying machine independent recognition, navigation, fixed the point, quantitative spraying; fully improve work efficiency and ease the labor shortage, improve operational safety and health of the environment, and increase the quality of spraying operations; can reduce the amount of pesticide spraying and increase the utilization rate of pesticides and reduce the pollution of pesticides on air, water, soil, farm products, and maintain the sustainable development of agriculture.

Description

technical field [0001] The invention relates to a path identification method, in particular to a navigation path identification method for a spraying machine in a cotton field. Background technique [0002] At present, the vast majority of pesticide spraying machines used in my country are manually operated, and the sprayers decide the time, place and dosage of chemical agents based on experience, which results in the abuse of these agricultural chemicals, thus Restricted the sustainable development of my country's agricultural production. In addition, during the entire pesticide spraying operation, the labor intensity of the operators is high, and the operators are directly exposed to the pesticides, so they are extremely vulnerable to the injury of the pesticides. At the same time, due to manual operation, the efficiency of the whole pesticide spraying operation is not high. Therefore, it is of great significance to study the navigation path identification of spraying mac...
