1、rainysky陪你一起在Zedboard上移植qt+opencv(六)：在Zedboard上运行Opencv和在PC机上一样，建立文件夹optzedboardOPenCV_zed,复制文件进来,解压缩：建立两个文件夹bui1d、insta11,如下图rootrainysky:opencv_zed#Is3jopencv-2.4.40penCV-2.4.4a.tar.bz2a；root0ratnysky:opencv_zed#cdopencv-2.4.4/bTOOt$ratnysky:opencv-2.4.4#nkdtrbui1drrootratnysky:opencv-2.4.4mkdtrin

7、tzedboardopencv-zedcode在里面新建一个测试程序：vimedge_detecti_on.cpp这个代码是教材里面带的那个：/*code*/inc1udecv.hinc1udehighgui.hIp1Image*doCanny(Ip1Image*in,doub1eIowThresh,doub1ehighThresh,doub1eaperture)(if(in-nChanne1s!=1)return(0);/Cannyon1yhand1esgraysca1eimagesIp1Image*out=CvCreateImage(CvGetSize(in),in-depth,/IP1D
