You can be using the addWeigh method to draw result image RGB Image.

You can be using this example from OpenCV example. https://github.com/opencv/opencv/tree/master/samples/android/face-det

Have not measured_distance value? How to auto measure it.

You can install OpenCV Manager APK directly from APK folder in the OpenCV Source that you have downloaded.

You must calibration camera(find extrinsic and intrinsic camera matrix, Use can using cheeboard or Calibrated Cameras in

@earcz certainly

@earcz This is also a problem that I am also looking for a solution. If you have a solution, please show me.

How to measure distance(measured distance) auto? You can explant me how to? the AR how to do that?

@Michal The line of the spot parking on your image is too blurry. I think it is difficult to do this.

@Akhil Patel. I have the reference for you above comments. https://github.com/opencv/opencv/tree/master/samples/androi

Thank you so much. This wiki I have read it. The same as this http://ksimek.github.io/2013/08/13/intrinsic/

How to measuring like AR? Do you have any ideas?

I think, before do Canny, you should adjust brightness and contrast value. You can do this by way: Changing the contra

You should be moving findRectangle and angle method into JNI.

This error has happened when JNI have not including OpenCV lib.

You should using Canny detect edges, this is simple. https://docs.opencv.org/3.4.3/d6/d56/samples_2cpp_2edge_8cpp-exampl

Hi guys, Have anyone could help me resolve this issue, or have any idea.

After applying a series of algorithms, I have the following result.

How to draw line look like bellow.

I have to apply HoughLineP but not good.

Code ``` pyrMeanShiftFiltering( img, res, spatialRad, colorRad, maxPyrLevel );

//imshow( "ShiftFiltering", res );

cvtColor(res, res, COLOR_RGBA2GRAY);

GaussianBlur(res, res, Size(15, 15), 0);

//imshow( "GaussianBlur", res );
adaptiveThreshold(res, res, 255, ADAPTIVE_THRESH_GAUSSIAN_C, THRESH_BINARY_INV, 11, 1);
//imshow( "adaptiveThreshold", res );

Mat element = getStructuringElement (MORPH_RECT, Size(3, 3));
morphologyEx(res, res, MORPH_CLOSE, element);

Mat edgs;
Canny(res, edgs, 750, 800, 3);
vector<Vec4f> lines3;
HoughLinesP(edgs, lines3, 1, CV_PI / 180, 20, 15, 10);

Mat markEdges = Mat(res.size(), CV_8UC3);
for (size_t i = 0; i < lines3.size(); i++)
{
    Vec4f l = lines3[i];
    double dest = euclideanDist(Point2f(l[0], l[1]), Point2f(l[2], l[3]));
    if (dest > 10) {
        line(markEdges, Point2f(l[0], l[1]), Point2f(l[2], l[3]), Scalar(0, 0, 255), 2, LINE_AA);
    }
}

imshow("markEdges", markEdges);

``` I have applied segment image (watershed) but not good.
