In this paper, we present a method to automatically estimate the geometric relations among the different views of cameras with partially overlapping fields of view in a wireless video-surveillance system. The method uses the locations of the detected moving objects visible at the same time in two or more views. The correspondences among objects are found by comparing their appearance models based on dominant colour descriptors while the geometric transformation are computed iteratively and may be used to solve the consistent labelling problem.As a significant part of the processing is performed on the smart cameras, the method has been conceived by taking into account the limited resources and low computational capability of the aforementioned devices. Experiments are done on publicly available datasets in order to show the accuracy of the geometric relations found by our method.
