我使用opencv 2.4.3使用以下代码执行向量到矩阵转换:
struct Component { cv::Rect Box; double area; double circularity; } int main ( ... ) { cv::vector < Component > components; cv::Mat componentMat ( components,true ); std::cout << componentMat; return 0; }
OpenCV Error: Unsupported format or combination of formats() in unkNown function,file ...\opencv\modules\core\src\out.cpp,line 111
解决方法
在
the documentation中,有一个Mat构造函数的引用,它们表示支持哪种类型的向量:
“The constructor can handle arbitrary types,for which there is
properly declared DataType,i.e. the vector elements must be
primitive numbers or uni-type numerical tuples of numbers. Mixed-type
structures are not supported,of course.”
