FPR -- Fast Path Risk Algorithm to Evaluate Collision Probability [PDF]
, 2019 As mobile robots and autonomous vehicles become increasingly prevalent in human-centred environments, there is a need to control the risk of collision. Perceptual modules, for example machine vision, provide uncertain estimates of object location.
