Image processing

Question

I want to get the boxes count in a warehouse by using image processing edge detection techniques. So I used Sobel algorithm to detect edges. Now I need to measure the edge length. Does anyone know how to get length of edges and any suitable algorithm to get final count ?

Answer 1

You should consider using the Hough transform for identifying the boxes. The basic transform won't explicitly give you the length of the side of a particular box however, but it would be a good starting point.

Take a look at Localization of Piled Boxes by Means of the Hough Transform.
