I am trying to extract the length and width from a set lidar sensor points (pink) as shown in the image below. The points circled in blue and white are actually noise which I wish to eliminated. [The orange box is the length and width I currently have calculated from the points. As seen, the calculated width is much 1/3 wider than it is supposed to be, due to the noisy points i blue and white]

I've read some approaches to do corner/rectangle fitting, then discarding x% of the poorest fitting points. This would help me to get rid of the circled points. But so far, after many searches I still cannot find any concrete implementations on how to do this fitting.

Can any provide any suggestions how I can go about doing this? enter image description here

  • "the orange box is the calculated box size": what does that mean ??? –  Dec 03 '16 at 09:51
  • Please draw precisely the "corner" that you expect to get. Without this info, it is hard to answer. –  Dec 03 '16 at 09:53
