Problems solved by technology

[0003] Based on the consideration of reducing the labor intensity of cotton farmers and accelerating cotton picking efficiency, mechanized cotton picking technology is more and more widely used, but most of the cotton picking machines used in China are imported from abroad. On the one hand, the price is high and the picking conditions are harsh. On the one hand, most imported cotton pickers need to be sprayed with defoliants, which will affect the quality of cotton

Embodiment 1

[0030] A cotton identification and positioning method based on a binocular camera. In an actual cotton field, the cotton identification method based on a binocular camera encapsulates the left and right cameras into a group of cameras, and uses three groups of cameras to collect images around the cotton.

[0031] like figure 1 As shown, the specific process of the cotton recognition method based on the binocular camera is as follows:

[0032] (1) Calibrate the binocular camera and obtain the parameters of the binocular camera, including the internal and external parameters of the camera;

[0033] (2) Use the binocular camera to collect the left and right color images of the cotton field, correct the camera image, and perform image matching to obtain the depth image in the camera field of view;

[0034] (3) Find the two-dimensional image positions of all cotton in the field of view through the cotton recognition algorithm;

[0035] (4) Combining the internal and external para...

Abstract

The invention discloses a cotton identifying and positioning method based on a binocular camera, comprising the steps of calibrating the binocular camera and obtaining the internal and external parameters of the camera; collecting the left and right images of cotton field by means of the binocular camera, and calculating the depth images; finding the position of cotton among colored images through the cotton identification algorithm; calculating the 3D information of all cotton by combining the camera parameter, the depth images, and the 2D image positions of cotton. The cotton identifying and positioning method based on a binocular camera is advantageous in that labor intensity is reduced and work efficiency is improved; cotton-picking cost is declined; cotton quality is enhanced.

Description

technical field [0001] The invention relates to a cotton identification and positioning method, in particular to a binocular camera-based cotton identification and positioning method, which is applied to an intelligent cotton picker system and belongs to the field of cotton identification and positioning methods. Background technique [0002] The key issue of intelligent cotton picker is cotton identification. The existing cotton identification mainly includes several methods based on ultrasonic technology, near-infrared technology and remote sensing technology. [0003] Based on the consideration of reducing the labor intensity of cotton farmers and accelerating cotton picking efficiency, mechanized cotton picking technology is more and more widely used, but most of the cotton picking machines used in China are imported from abroad. On the one hand, the price is high and the picking conditions are harsh. On the one hand, most of the imported cotton pickers need to be spraye...
