Abstract

Fish swim freely in water and their 3D spatial interactions may carry important information for biological study. The two-dimensional Qualitative Trajectory Calculus (QTC2D), a spatiotemporal calculus, is a method for representing and reasoning about movements of objects in a qualitative framework. This emerging technique encodes the spatial geometric relationships between distinct objects, such as machines, humans or animals. This paper presents a method for generalising QTC2D into 3D space, called 3DQTC, as a work-in-progress. The 3DQTC method is based on a geometrical analysis method of estimating the 3D orientation of �fish. Initial results indicate the potential of representing and analysing the �fish behaviours in 3D space. 3DQTC is also demonstrated as a means of extracting useful information (e.g. follow and non-follow behaviours)which cannot be achieved by QTC2D. We conclude by discussing further work and development.
