FLoTS-SLAM Uses Optical Flow Uncertainty to Improve Dynamic SLAM Accuracy
1 reports · 1 sources
Haorui Du and Lipu Zhou propose FLoTS-SLAM, which derives motion uncertainty from the residual between optical flow and camera-motion-induced optical flow, for monocular RGB SLAM in dynamic scenes. The system first estimates camera pose using high-confidence pixels, then reprojects dynamic pixels to jointly optimize pose and depth, reducing the impact of object motion on pose and depth updates. The paper claims that on DAVIS, the average IoU of dynamic masks improves by 35% over advanced baselines, and on Bonn and TUM, the average ATE is reduced by 59% and 19% respectively relative to the SLAM backbone used; the source code will be made public.
