1 打开python编译器，并加载opencv模块和图片。# -*- coding: utf-8 -*-import cv2imgpath = "C:/Users/Administrator/Desktop/a.png"img = cv2.imread(imgpath)cv2.imshow("Image",img)cv2.waitKey(0)2 运行一下，就可以看到图片。3 把图片变成灰度图：img0 = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)...
frame=cap.read()ifhas_frame:file_name=f'{idx:06d}.jpg'cv.imwrite(os.path.
opencv中读入、显示、写出图片:cv2.imread(), cv2.imshow(), cv2.imwrite() 1、cv2.imread() 代码语言:javascript 复制 importnumpyasnpimportcv2 # Load an color imageingrayscale img=cv2.imread('messi5.jpg',0) 第二个参数是要告诉函数应该如何读取这幅图片。 • cv2.IMREAD_COLOR:读入一副彩色图像。
3.如果读取的图片宽度大于256,则输出的excel文件若使用wps打开只能看到最大列为256,excel2007以上可以看到全部数值。 代码语言:cpp 复制 voidCSpectrumProDoc::OnExportexcel(){// TODO: 在此添加命令处理程序代码CString sPath=_T("D:\\Image\\");//注意不能是c盘的路径,没有权限写入CTime time=CTime::GetC...
