I am using OpenCV 4.10.0 for my project to run YOLOv9, as it is the only version with which I have been able to execute YOLOv9 correctly. The problem arises when I use cv::cvtColor in conjunction with YOLOv9 and other OpenCV functions. Specifically, if I uncomment the line: cv::c...

_src.empty() in function 'cv::cvtColor' 我在运行的时候报错,如下图 cv2.error: OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor' 然后去网上查找解决办法,总结一下会出现的几种问题 1...
_src.empty() in function 'cv::cvtColor' 是由OpenCV 库抛出的,它通常表示在尝试对一个空图像(即未成功加载的图像)执行颜色空间转换时出现了问题。 要解决这个问题,我们可以按照以下步骤进行: 确认错误信息的含义: 这个错误表明 cv::cvtColor 函数试图在一个空的图像上执行操作,即 src 图像为空(_src.empty...

1,勾选BUILD_opencv_world,把他集成一个dll文件。 2.找到OPENCV_EXTRA_MODULES_PATH项,设置为opencv_contrib3.4.1目录下的moduless文件夹 设置好后再次点击 configure ,然后点击 generate . 然后CMake完成 备注:(1)背景变成白色即可 如果不行再次点击 configure 变白后再点击generate,可多点几次。
