The embodiment of the invention discloses a crane four-rope grab bucket torsion angle calculation method and system based on YOL0v5, and the method comprises the following steps: firstly, triggering an image collection unit through a crane PLC control program, and capturing an image of a four-rope grab bucket in real time; then, preprocessing the image by using a lightweight YOLOv5 algorithm, and extracting feature information; then, recognizing grab bucket features in the image by using a YOLOv5 algorithm, and determining the position of the grab bucket features; then, the rotating coordinate value of the lifting appliance is calculated through coordinate transformation; and finally, calculating and outputting the torsional angle of the grab bucket according to the rotating coordinate value. According to the method, by optimizing the YOLOv5 algorithm and lightweight design, the grab bucket recognition precision and the system operation efficiency are improved, the torsional angle of the four-rope grab bucket can be output in real time through accurate coordinate transformation and rotation angle calculation, and accurate feedback and control basis is provided for crane operation.
