Web4 de jan. de 2024 · This representation is used in OpenCV). So Any line can be represented in these two terms, (r, θ). Working of Houghline method: First it creates a 2D array or accumulator (to hold values of two parameters) and it is set to zero initially. Let rows denote the r and columns denote the (θ)theta. Size of array depends on the accuracy you need. 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. References:
