The aim of this work is to implement a people detection and tracking algorithm using the time-of-flight camera SwissRanger 3000. This kind of camera is able to measure both the grayscale image of the scene and the depth for each pixel. With these two types of information the images coming from the camera can be processed to extract the blobs present on them, detect people moving and track them in the video. Besides the interest will be pointed not only on the results that can be obtained, but also on the analysis of the limitations and problems encountered using this camera prototype." }
