Web4 de jul. de 2024 · Let assume that on every image I have only one line, the line can be only vertical or horizontal, the crack on the line can be either perpendicular or at an angle (different than 90 degrees which I understand as perpendicular). Resuming we can have 4 situations: horizontal line, perpendicular crack (as in the image that we already discussed)

The following code will distinguish between the two (0 degrees for horizontal, -89.999999 degrees for vertical).
Web24 de ago. de 2024 · In this article, we have seen how to detect the orientation of given objects using PCA and OpenCV. As you can see the first principal component is directed so well which gives the clear orientation of objects. Further one can explore this code to detect the orientation of different kinds of objects and see the interesting result.
