我是Android的OpenCV新手.我正在尝试将C++代码转换为Java.我陷入了某些困境,我无法继续.

std::vector<cv::Vec4i> lines;
cv::HoughLinesP(bw, lines, 1, CV_PI/180, 70, 30, 10);

    // Expand the lines
    for (int i = 0; i < lines.size(); i++)
    {
        cv::Vec4i v = lines[i];
        lines[i][0] = 0;
        lines[i][1] = ((float)v[1] - v[3]) / (v[0] - v[2]) * -v[0] + v[1]; 
        lines[i][2] = src.cols; 
        lines[i][3] = ((float)v[1] - v[3]) / (v[0] - v[2]) * (src.cols - v[2]) + v[3];
    }

我改变了一半..直到TODO

MatOfInt4 lines= new MatOfInt4();
Imgproc.HoughLinesP(bw, lines, 1, Math.PI/180, 70, 30, 10);

int[] lineArray = lines.toArray();
