System, method and device for identifying and positioning abnormal plants

The invention discloses a system, method and device for abnormal plant identification and positioning, and the method comprises the steps: pre-training an abnormal plant identification model of a to-be-identified region, and inputting the model into an intelligent terminal; when the unmanned aerial vehicle carries the intelligent terminal to search a to-be-recognized area in real time, if a suspected target appears, a shooting mechanism of the intelligent terminal shoots the target through a speed compensation mechanism, and recognizes, classifies and positions the shot target image, thereby achieving the recognition and positioning of abnormal plants. The invention further discloses a system for recognizing and positioning the abnormal plants, effective recognition, accurate positioning, auxiliary impurity removal and effect evaluation of the abnormal plants in the seed production process are achieved, and the purpose of improving the seed production quality and purity of hybrid rice is achieved. 本发明公开一种用于杂株
