使用左右侧的蓝框矩形角点, 计算左右两张图之间的仿射矩阵M M = cv.getPerspectiveTransform(point1, point2) # points1是左侧的4个矩形角点,points2是右侧的4个矩形角点 2. 因为五角星针对蓝矩形框的相对位置是不变的[在任意图形中, 即使蓝框会在整图中轻微旋转偏移]. 所以求出左右两个蓝框角点间的M仿射矩阵...
cv2_letterbox_image、增强mixup、旋转仿射（使用getRotationMatrix2D和cv2.warpAffine）和椭圆变圆（使用cv2.fitEllipse）等技术用于图像预处理，有助于提升模型训练效率和准确性。边缘提取技术如cv2.ximgproc.createEdgeDrawing()可快速检测图像中的所有边缘、线和椭圆，适用于图像分析和特征提取。目标跟踪技术...
