Project 1 - Lane Finding - region_of_interest OpenCV error #577

Closed frankcarey closed 6 years ago

frankcarey commented 7 years ago

Posted a github issue to https://github.com/udacity/CarND-LaneLines-P1/issues/35

The region_of_interest() function says it takes vertices which it passes to cv2.fillPoly(), but it seems like what that function is supposed to take is an Array of shapes.

I think that function should be updated like so:

-cv2.fillPoly(mask, vertices, ignore_mask_color) +# We need to pass in an array of shapes (each shape is an array of vertices) +cv2.fillPoly(mask, [vertices], ignore_mask_color) Causes error: error: /home/travis/miniconda/conda-bld/conda_1486587071158/work/opencv-3.1.0/modules/imgproc/src/drawing.cpp:2276: error: (-215) p.checkVector(2, CV_32S) >= 0 in function fillPoly

We're now tracking repository-specific issues on the Waffle board as well, so I'm closing this one out to focus on the original :)
