Abstract
People tracking is a key technology for autonomous systems,
intelligent cars and social robots operating in populated envi-
ronments. What makes the task difficult is that the appearance
of humans in range data can change drastically as a function
of body pose, distance to the sensor, self-occlusion and oc-
clusion by other objects. In this paper we propose a novel ap-
proach to pedestrian detection in 3D range data based on su-
pervised learning techniques to create a bank of classifiers for
different height levels of the human body. In particular, our
approach applies AdaBoost to train a strong classifier from
geometrical and statistical features of groups of neighboring
points at the same height. In a second step, the AdaBoost
classifiers mutually enforce their evidence across different
heights by voting into a continuous space. Pedestrians are fi-
nally found efficiently by mean-shift search for local maxima
