Keywords: Blind spot, optical flow, obstacle detection
We describe an optical flow based obstacle detection system for use in
detecting vehicles approaching the blind spot of a car on highways and
city streets. The system runs at near frame rate (8-15 frames/second)
on PC hardware. We will discuss the prediction of a camera image given
an implicit optical flow field and comparison with the actual camera
image. The advantage to this approach is that we never explicitly calculate
optical flow. We will also present results on digitized highway images, and
video taken from Navlab 5 while driving on a Pittsburgh highway.
