A loading question when I use OpenCV load a picture-CodePudding

When I use the complier it gives me the error code :

    OpenCV(4.2.0) Error: Assertion failed (!_src.empty()) in cv::cvtColor, 
    file C:\build\master_winpack-build-win64-vc14\opencv\modules\imgproc\src\color.cpp, line 182

I located where the problem occurred in this part :

    auto texture_path = "hmap.jpg";
    Texture texture = Texture(obj_path   texture_path);
    r.set_texture(texture);

And the obj_path :

    std::string obj_path = "../models/spot/";

When I creat the texture I use the function :

    Texture(const std::string& name)
        {
            image_data = cv::imread(name);
            cv::cvtColor(image_data, image_data, cv::COLOR_RGB2BGR);
            width = image_data.cols;
            height = image_data.rows;
        }

The problem happend in 4th line cv::cvtColor(image_data, image_data, cv::COLOR_RGB2BGR);

I have checked the path, my file structure is like this :

I don't konw why the problrm happend.

CodePudding user response：

obj_path texture_path is "../models/spothmap.jpg"

CodePudding user response：

I find change the obj_path to Assigment3/Code/models/spot/ can solve this question. The problem is taht I made a mistake on the default working directory when I run my project on my IDE.

CodePudding user response：

your Code and all file directories should be at the same location. It's major problem to install in the terminal. Please check the first file directory.
