N2 - This paper proposes a method for reconstructing qualitative positions of landmarks by using geometrical constraints. The acquisition process iterates the following steps: (1) observing relations among landmarks and motion directions of moving objects, (2) classifying the landmarks into a pair of landmark sets which are classified with a straight line, (3) acquiring three-point constraints from the pair, and (4) propagating the constraints. We have applied this method to acquisition of qualitative positions of multiple vision sensors in a distributed vision system, and evaluated it with simulations.
