I tried to use the Matlab command 'lineToBorderPoints', but it only displays the epilines in a diagram and not in my actual image that i wanted. As shown in the image in the attachment. How can I fix this issue? I did the exact same as in the documentation.
F = stereoParams.FundamentalMatrix;
epiLines_left = epipolarLine(transpose(F),centroids_right); % centroids_right is the point i want to intersect
subplot(1,2,1);
hold on
points = lineToBorderPoints(epiLines_left,size(bw_left)); % bw_left and bw_right are the images
line(points(:,[1,3])',points(:,[2,4])');
hold off
epiLines_right = epipolarLine(F,centroids_left);
subplot(1,2,2);
hold on
ids = transpose(1:size(centroids_left,1));
points = lineToBorderPoints(epiLines_right,size(bw_right));
line(points(:,[1,3])',points(:,[2,4])');
hold off

display the image, and hold on, and plot, and hold off, if the requirements are to display the lines over the image .
If you need to build a new image with the lines in it then after you have called the function to calculate the points then use the points as information for computer vision insertShape
