Question

opencv中call to non-static member function without an object argument

template<typename _Tp> inline MatND_<_Tp>& MatND_<_Tp>::operator = (const MatND& m)

{

if( DataType<_Tp>::type == m.type() )

{

Mat::operator = (m);

return *this;

}

if( DataType<_Tp>::depth == m.depth() )

{

return (*this = m.reshape(DataType<_Tp>::channels));

}

CV_DbgAssert(DataType<_Tp>::channels == m.channels());

m.convertTo(*this, DataType<_Tp>::type);

return *this;

}

在Mat::operator = (m);出现错误
错误提示是call to non-static member function without an object argument 请问是什么原因怎么修改

Answer 1

Mat类中的=函数是静态成员函数吗？=是初始化mat对象的，这么用不对。等号左边却一个mat的对象。
