Small bug fixes. Switching the dimension of the projected image and switch from bgr to rgb.

Hi, thanks for this awesome package. I tried to use it on the kitti dataset and the output seemed not right. So I needed to do 2 small changes. I'm not sure if it was just my setup, but if you want you can have a look at the changes. I attached a image of my output with the changes.

Image for reference without the changes.
