opencv使用remap函数后得到的图片无法显示

Question

initUndistortRectifyMap(cameraMatrixL, distCoeffL, Rl, Pr, cv::Size(boardwidth, boardheight), CV_32FC1, mapLx, mapLy);
	initUndistortRectifyMap(cameraMatrixR, distCoeffR, Rr, Pr, cv::Size(boardwidth, boardheight), CV_32FC1, mapRx, mapRy);

	cv::Mat rectifyImageL, rectifyImageR;
	remap(image1, rectifyImageL, mapLx, mapLy, cv::INTER_LINEAR);
	cv::FileStorage fw1("rectify.xml", cv::FileStorage::WRITE);
	fw1 << "mat" << rectifyImageL;

	remap(image2, rectifyImageR, mapRx, mapRy, cv::INTER_LINEAR);
	cv::namedWindow("rectifyImageL", cv::WINDOW_AUTOSIZE);
	cv::imshow("rectifyImageL", rectifyImageL);
	cv::imshow("rectifyImageR", rectifyImageR);

你的图片应该没有数据吧，你试试将数据另存为一张图片试试
