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.

    本申请公开了本申请实施例提出的基于YOL0v5的起重机四绳抓斗扭角计算方法及系统,包括如下步骤:首先,通过起重机PLC控制程序触发图像采集单元,实时捕捉四绳抓斗的图像;然后,利用轻量化YOLOv5算法对图像进行预处理,提取特征信息;接着,使用YOLOv5算法识别图像中的抓斗特征,并确定其位置;之后,通过坐标转换计算出吊具的旋转坐标值;最后,根据旋转坐标值计算并输出抓斗的扭角。该方法通过优化YOLOv5算法和轻量化设计,提高了抓斗识别精度和系统运行效率,通过精确的坐标变换和旋转角度计算,能够实时输出四绳抓斗的扭角,为起重机作业提供了准确的反馈和控制依据。
