Abstract

In this paper, we propose a method for estimating time-to-contact (TTC) of moving objects and cameras in underwater environments. The time-to-contact is useful for navigating moving vehicles and for avoiding collisions in the 3D space. The existing methods calculate time-to-contact from geometric features of objects such as corners and edges. However, if the cameras and objects are in scattering media, such as fog and water, the degradation of image intensity caused by light scattering makes it difficult to find geometric features in images. Thus, in this paper we propose a method for estimating time-to-contact in scattering media by using the change in image intensity caused by the camera motion.
