Abstract

The invention relates to an automatic identification method and device for in-row weeds in the seedling stage of transplanted crops. The device comprises a darkroom system constructed by sectional materials; an RGB camera is fixed at the top end in the darkroom system and is connected with a computer; six color code sensors are fixed at the bottom end in the darkroom system, signal lines of the color code sensors are connected with a computer through an Arduino single chip microcomputer, and power lines of the color code sensors are connected with a transformer; transplanted crop seedlings are located at the symmetric center of the six sensors and right face the RGB camera, and weeds exist on the left side and the right side of the transplanted crop seedlings. Through a series of designs, the signal transduction technology is adopted, images captured from the top are analyzed, transplanted crop seedlings and weeds in the images are selected in a frame mode, and then the transplanted crop seedlings and weeds are distinguished through information sent back by a color code sensor. A new machine vision and signal transduction method based on the geometric appearance of the transplanted crop seedlings is established, and the positions of the crop seedlings and weeds in the field are accurately recognized.

Description

technical field [0001] The invention relates to the field of weeding, in particular to a method and device for automatic identification of in-row weeds at the seedling stage of transplanted crops based on a color code sensor and computer vision. Background technique [0002] Weed control is one of the important issues in the production of transplanted crops. Weeds compete with transplanted crops for resources such as nutrients, sunlight, and water. If weeds are not controlled, the yield of transplanted crops will be greatly affected. Compared with inter-row weeds, in-row weeds are more harmful to crops. According to statistics, the number of weeds emerging in transplanted crops is the largest within three weeks after transplanting. Grass control is very important. [0003] At present, spraying herbicides, mechanical intertillage weeding and manual weeding are common means of weed control. Herbicides are currently the main means of weed control due to their ease of use and...
