错误:使用OpenCV时垫子模棱两可 [英] Error: Mat is ambiguous when using OpenCV

问题描述

我在C ++中还很陌生，我正在尝试使用OpenCV提供的某些库.问题是，当我将代码放在下面时，它说:

I am pretty new in c++ and i am trying to use some of the libraries OpenCV is offering. The problem is that when i put the code below it says:

Error: Mat is ambiguous

，我在其他帖子中已经读过，这意味着编译器无法选择要选择的函数，但这也正是OpenCV教程中调用它的方式. http://docs.opencv.org/doc/tutorials/introduction/display_image /display_image.html

, which i have read in other posts that means that the compiler cannot pick which function to choose, but this is exactly how it was called in the OpenCV tutorial too. http://docs.opencv.org/doc/tutorials/introduction/display_image/display_image.html

Mat A;

到目前为止，我编写的代码位于.h文件中:

The code i have written till now is in the .h file:

#pragma once
#include <E:\opencv\build\include\opencv2/highgui/highgui.hpp>
#include <E:\opencv\build\include\opencv2/core/core.hpp>

using namespace cv;
class Face_Detection
{
public:
    Face_Detection();

    ~Face_Detection();

};
int main(){

    cv::Mat image;
    //A = imread(argv[1], CV_LOAD_IMAGE_COLOR);

    return 1;
}

推荐答案

您可以包括其他也定义了Mat类型的库/文件.尝试使用，即通过显式添加其命名空间cv，

You may include other lib/file that also defines a Mat type. Try to use, i.e. by explicitly add its namespace cv,

cv::Mat A;

反而避免歧义.

您包含OpenCV头文件的方式使我感到您没有正确使用OpenCV.尝试首先按照以下文章正确设置OpenCV，包括include/library/....

The way you included OpenCV header files make me feel you didn't use OpenCV properly. Try to first follow the following post to setup OpenCV correctly, including include/library/....
