Vertical line for building detection

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]

See Line detection here

Hope you know how to apply mask on images. This would be more obvious to answer, if you can attach a sample image.

Thanks Kalyan for your reply. I need similar lines as this link page pictures

I need to merge camera images with 2d laser data so that height of buildings can be mentioned and also it helps in localization.
