Robots create maps of generic objects segmented from camera images
Maps aligned between robots by new Temporally Consistent Frame Alignment Filter
Filter rejects incorrect alignments using multiple hypotheses and consistency
Enables team to share people observations in common frame
Hardware demo: 4 robots track 6 people with accuracy close to ground truth
Team of robots track moving people by sharing object observations
A team of mobile robots can more accurately track moving people in their environment by sharing observations of people's locations with each other in real-time. But robots accumulate error in their position estimates, so they must repeatedly estimate the change in coordinate frames between themselves and neighbors. This paper presents a full system for robots to build maps of generic objects seen recently, align the maps to estimate relative positions, and use those to share observations of people for collaborative tracking.
