其中Mosaic,仿射矩阵增强都是针对(X_LT, Y_LT, X_RB, Y_RB)数据格式进行增强,修改时添加θ维度就可以,不过仿射矩阵增强函数内共有 Translation、Shear、Rotation、Scale、Perspective、Center 6种数据增强方式,其中旋转与形变仿射的变换会引起目标角度上的改变。 所以只要超参数中的 ['perspective']=0,['degrees'...

This paper proposes a vehicle target detection method in remote sensing images based on YOLOV5 rotation box regression, which mainly includes: the loss function is improved; a rotating target detection method is designed to improve the detection accuracy of the net-work. It uses remote sensing ...
