Avoiding negative depth in inverse depth bearing-only SLAM [PDF]

open access: yes, 2008
In this paper we consider ways to alleviate negative estimated depth for the inverse depth parameterisation of bearing-only SLAM. This problem, which can arise even if the beacons are far from the platform, can cause catastrophic failure of the filter.We

Depth

open access: yesi-Perception, 2011
