For the analysis of object movements using cameras, generally in public places, objects whose movement can be followed and analysed on the basis of the existing trajectories is determined on the basis of grey shade, colour and texture features, and detection of variations and movement vector fields,. The identification of objects technically represents, however, a non-robust working step which often leads to incomplete or false trajectories and therefore to poor analysis results, which is to be avoided in the invention. To this end, according to the invention, the individual movement vectors in the observation region are associated with applied geometry models, and path-time diagrams are drawn up from such a value assignment and compared to speed models. The invention can be applied to the detection of object movements by means of image analyses. |
