Lane Detection

The following livescript uses MATLAB functionalities to simulate the lane detection application.

Read input image.

inImgPath = 'data/lane_detection.jpg';

inImgUMat = nxpvt.imread(inImgPath);

if isempty(inImgUMat)

fprintf('Failed to open input image: %s.', inImgPath);

return;

end

nxpvt.imshow(inImgUMat);

Create resize object.

ratio = 1;

resizeObj = nxpvt.apexcv.Resize();

Apply Lanemarking algorithm to grayscale image.

laneVerticesAlgorithm = lanemarking_Algorithm(inImgUMat);

Add results on to the original image.

laneImageAlgorithm = nxpvt.cv.insertLines(inImgUMat, laneVerticesAlgorithm);

laneImageAlgorithm = Process(resizeObj, laneImageAlgorithm, ratio);

nxpvt.imshow(laneImageAlgorithm);
