cv::FileStorage(const std::string &filename, int flags):根据指定的文件名和标志打开文件。标志可以是cv::FileStorage::READ(读取模式)或cv::FileStorage::WRITE(写入模式)。 常用标志: cv::FileStorage::READ:打开文件进行读取。 cv::FileStorage::WRITE:打开文件进行写入。 cv::FileStorage::APPEND:追加模式。
在OpenCv中,我们有时候需要查看CvRect变量的值,我们可以通过将其保存到文件来查看,保存的代码如下: voidwriteCvRectToFile(CvRect &rect,constchar*filename) { CvFileStorage*fs = cvOpenFileStorage(filename,0, CV_STORAGE_WRITE);if(!fs) { fprintf(stderr,"Could not open file ..\n");return; } cvS...
#写文件 model_settings=cv.FileStorage("mytest.yaml",cv.FILE_STORAGE_WRITE) model_settings.write('version','v1.0') model_settings.write('author','gloomyfish') model_settings.write('param1',param1) model_settings.write('param2',param2) model_settings.write('param3',param3) model_settings....
CV_STORAGE_WRITE); cvWrite(fs,"points_matrix", pts); cvReleaseFileStorage(&fs); <!-- Code inserted with Steve Dunn's Windows Live Writer Code Formatter Plugin. http://dunnhq.com --> 反之,从本地xml文件中读入CvMat数组,再转换为 vector 格式,方式如下: CvFileStorage*fs=cvOpenFileStorage("dat...
于是,存储器(memorystorage)就如同栈(Stack)那样, bottom指向栈底,(top, free_space)对指向栈顶。栈顶可通过cvSaveMemStoragePos保存,通过cvRestoreMemStoragePos恢复指向,通过 cvClearStorage重置。 1.3 CvMemBlock 内存存储块结构 typedef struct CvMemBlock { struct CvMemBlock* prev; struct CvMemBlock* next; } ...
storage = cvCreateMemStorage(); //功能:创建新序列。并初始化写入部分 cvStartWriteSeq( 0, sizeof( CvSeq ), sizeof( haarFeature ), storage, &writer ); for( x = 0; x < winsize.width; x++ ) { for( y = 0; y < winsize.height; y++ ) ...
可能是你的sizeof(CvSeq) 的问题，给你一个demo，亲测有效 void DrawBox(CvBox2D box,IplImage* img,CvScalar scalar){ CvPoint2D32f point[4];int i;for ( i=0; i<4; i++){ point[i].x = 0;point[i].y = 0;} cvBoxPoints(box, point); //计算二维盒子顶点 CvPoint pt[4]...
