Vertical line for building detection
显示 更早的评论
Hi
I am finding a way to identify vertical building lines from camera images -offline so that it can be used for mapping purpose.
currently like tall building, vertical line of building is required (source from camera images) to estimate bulding location and isolate building from other scenes.Any one can help me?

You can do the thresholding or oher image suitable segmentation approach to get the ROI, (preferbly vertical). In that case, you can use the following kernel operation to locate the vertical lines (choose the mask size accordingly)
ker=[-1 0 1
-1 0 1
-1 0 1]
Hope you know how to apply mask on images. This would be more obvious to answer, if you can attach a sample image.
