Abstract
Described is a system for collision detection and avoidance estimation using sub-region based optical flow. During operation, the system estimates time-to-contact (TTC) values for an obstacle in multiple regions-of-interest (ROI) in successive image frames as obtained from a monocular camera. Based on the TTC values, the system detects if there is an imminent obstacle. If there is an imminent obstacle, a path for avoiding the obstacle is determined based on the TTC values in the multiple ROI. Finally, a mobile platform is caused to move in the path as determined to avoid the obstacle.
