The current developments in robotics aim towards a usage in households and small and medium-sized enterprises. In this case it is necessary to coordinate human and robot by describing the task in a common model. Precedence graphs are a possible representation of such a model. The generation of these is tedious especially for non-experts.We contribute a vision-based approach which generates precedence graphs based on a world representation generated by an registered eye-in-hand camera. To achieve this, we describe a world representation based on boundary representation models and a corresponding object recognition method. The results are used to generate the precedence graph by calculating the AND/OR graph as an intermediate step. We evaluate our approach based on several scene models and on a real world application.
