Describtion of scene orientation #12

Closed kukuruza closed 9 years ago

Satwik, could you also provide projective parameters, so that It's possible to get the zenith view of the scene?

I want to use it to make background subtraction compensate for scale of distant objects

If I am not wrong, you're talking about the Inverse Perspective Map right ?

Since we do not have exact perspective parameters, but crudely estimate them using road width and other information; I am not entirely sure at this point how to extract zenith view.

Will get back to you as soon as I figure out something.

I don't need an exact view, I just need to make sizes of cars far and close be similar +- 50%. So even coarse estimate would work.

I wanted to use e.g. imtransform http://www.mathworks.com/help/images/ref/imtransform.html for this, so you could output their parameters

Thanks
