Abstract:
In this paper, we propose a method for estimating time-to-contact in scattering media, such as fog. Images taken in the scattering media are unclear, and thus, we cannot detect appropriate geometric information from images for computing 3D information. In this paper, we consider not geometric information but photometric information such as observed intensity. In our method, we can eliminate the effect of scattering media and estimate the time-to-contact toward objects without any prior knowledge.
