大佬教程收集整理的这篇文章主要介绍了将库OpenCV 2.4.2连接到xcode 4.5.1上,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
我也搜索并尝试在stackexchange和google上的其他变体,但这似乎让我最接近.
它似乎适用于某些事情,但不适用于2.4.2附带的示例代码.请注意,我已经添加了所有opencv 2.4.2 dylibs链接二进制与库.
例如,以下将编译并运行:
#include <opencv2/opencv.hpp> #include <opencv2/highgui/highgui.hpp> int main ( int argc,char **argv ) { cvNamedWindow( "My Window",1 ); IplImage *img = cvCreateImage( cvSize( 640,480 ),IPL_DEPTH_8U,1 ); CvFont font; double hScale = 1.0; double vScale = 1.0; int lineWidth = 1; cvInitFont( &font,CV_FONT_HERSHEY_SIMPLEX | CV_FONT_ITALIC,hScale,vScale,lineWidth ); cvPutText( img,"Hello World!",cvPoint( 200,400 ),&font,cvScalar( 255,255,0 ) ); cvShowImage( "My Window",img ); cvWaitKey(); return 0; }
但是,当我尝试构建任何示例,如display_image.cpp,示例如下,我得到链接错误.
– 不工作 –
#include <stdio.h> #include <iostream> #include "opencv2/imgproc/imgproc.hpp" #include "opencv2/highgui/highgui.hpp" #include "opencv2/flAnn/miniflAnn.hpp" using namespace cv; // all the new API is put into "cv" namespace. Export its content using namespace std; using namespace cv::flAnn; static void Help() { cout << "\nThis program shows how to use cv::Mat and IplImages converTing BACk and forth.\n" "It shows reading of images,converTing to planes and merging BACk,color conversion\n" "and also iterating through pixels.\n" "Call:\n" "./image [image-name Default: lena.jpg]\n" << endl; } int main(int argc,char *argv[]) { Help(); const char* imagename = argc > 1 ? argv[1] : "lena.jpg"; Mat img = imread(imageName); // the newer cvLoadImage alternative,MATLAB-style function if(img.empty()) { fprintf(stderr,"Can not load image %s\n",imageName); return -1; } if( !img.data ) // check if the image has been loaded properly return -1; Mat img_yuv; cvtColor(img,img_yuv,Cv_bGR2YCrCb); // convert image to YUV color space. The output image will be created automatically vector<Mat> planes; // Vector is template vector class,SIMILAR TO STL's vector. It can store matrices too. split(img_yuv,planes); // split the imagE into separate color planes imshow("image with grain",img); waitKey(); return 0; }
我收到以下错误:
Undefined symbols for architecture x86_64: "cv::split(cv::Mat const&,std::__1::vector<cv::Mat,std::__1::allocator<cv::Mat> >&)",referenced from: _main in main1.o "cv::imread(std::__1::basic_String<char,std::__1::char_Traits<char>,std::__1::allocator<char> > const&,int)",referenced from: _main in main1.o "cv::imshow(std::__1::basic_String<char,cv::_InputArray const&)",referenced from: _main in main1.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command Failed with exit code 1 (use -v to see invocation)
任何想法如何解决这个问题?
