Soybean inter-plant weed automatic identification device and method based on computer vision

Abstract

The invention discloses a soybean inter-plant weed automatic identification device and method based on computer vision. The device comprises a darkroom system built by section bars; the dark room system is covered by a black light absorption curtain; a gray-scale camera is fixed at the top end in the darkroom system, and is connected with a computer; six blue LED lamps are fixed in the middle of the interior of the darkroom system, and the blue LED lamps are connected with the transformer; and six mirrors with proper inclination angles are fixed at the bottom end in the darkroom system. Through a series of improvements, a systematic crop signal transduction technology is adopted, information, such as fluorescent images of soybean crops and weeds, captured from seven perspectives at the same time is analyzed, a new computer vision real-time identification method based on the three-dimensional geometric appearance of the soybean marker is established, the position of a soybean stem in a field is accurately identified, and the weeding device can be combined to realize automatic weeding operation.

Description

technical field [0001] The invention relates to the field of weeding, in particular to a device and method for automatically identifying weeds among soybean plants based on computer vision. Background technique [0002] Weed damage is one of the main biological disasters after soybean emergence, and inter-row weeds are more harmful to soybean seedlings. The number of weeds emerging within 3 weeks after soybean sowing can account for about 95.00% of the total number of weeds emerging, so the early control of weeds in soybean fields is particularly important. [0003] At present, measures such as herbicides, manual weeding and mechanical intertillage weeding are often used in weed control. Herbicide weed control is currently the main means of controlling weeds in soybean fields, but herbicide application is likely to cause problems such as agricultural product quality and safety and environmental pollution. Manual weeding is a flexible and precise inter-row weeding method, b...

AI Technical Summary

Problems solved by technology

The labeling process of the markers applied by the existing crop signal transduction technology is time-consuming and cumbersome, and it is impossible to prevent the markers from being cleared by sprinkler irrigation or natural precipitation.
