Coarse-grained soil broken particle tracking method based on improved YOLOv8

The invention relates to a coarse-grained soil crushing detection method based on improved YOLOv8, and the method comprises the following steps: S1, obtaining a coarse-grained soil crushing particle video; s2, making an original data set, marking the original data set, and then performing data enhancement before and after marking; s3, carrying out format conversion; s4, making a data set; s5, optimizing the YOLOv8 model; s6, training and optimizing to obtain a prediction model; s7, optimizing a strongsort algorithm; s8, acquiring tracking data, and outputting a motion track; and S9, converting the coordinate axis of the motion trail, converting the obtained tracking data from the pixel coordinate to the actual coordinate, and calculating to obtain the actual particle displacement and broken particle condition of the coarse-grained soil. According to the detection method, accurate tracking of coarse-grained soil broken particles in a coarse-grained soil geotechnical test is realized. 本发明涉及一种基于改进YOLOv8的粗粒土破碎检测方
