求助opencv报错R6010

[敲你脑壳]

	Mat edges;
       	Mat edges2;
	PylonInitialize();	
	CInstantCamera camera(CTlFactory::GetInstance().CreateFirstDevice());
	camera.Open();
	CImageFormatConverter formatConverter;

	camera.StartGrabbing(c_countOfImagesToGrab);
	camera.IsGrabbing();
	camera.RetrieveResult(5000, ptrGrabResult, TimeoutHandling_ThrowException);


	if (ptrGrabResult->GrabSucceeded())
	{
		formatConverter.Convert(pylonImg, ptrGrabResult);
		//CPylonImage转为Mat 
		edges = cv::Mat(ptrGrabResult->GetHeight(), ptrGrabResult->GetWidth(), CV_8UC1, (uint8_t *)pylonImg.GetBuffer());
	}
//到这里就报错
	imwrite("1", edges);
	//cvtColor(edges, edges2, CV_RGB2GRAY);

调用了pylon采集图像，图像能够正常采集，但是一旦opencv的处理函数就报错，高手帮忙给看看哈

执行到imwrite报错？保存图片的话，第一个参数是保存文件的路径，比如 1.jpg

我问题没说清楚，是执行cvtColor(edges, edges2, CV_RGB2GRAY); 就报错 不知谁能告诉我啊

[robertbo]

edges = cv::Mat(ptrGrabResult->GetHeight(), ptrGrabResult->GetWidth(), CV_8UC1, (uint8_t *)pylonImg.GetBuffer()); 这里edges创建的是CV_8UC1一灰度矩阵，是不能和CV_RGB2GRAY)配合用的 其实edges也是灰度图吧，为什么还要再进行一次转换呢？

CV_8UC1怎么往灰度转换？楼上说的对
