  • Multitarget Tracking Using Multiple Hypothesis Tracking

    The track¿¿?oriented multiple hypothesis tracking (MHT) algorithm is one of the most advanced algorithms for multisensor Multitarget tracking (MTT) for real¿¿?world complex problems. An MTT system uses one or more sensors such as radar, sonar, electro¿¿?optical, video, infra¿¿?red, multispectral, hyperspectral, and unattended ground sensor (acoustic and seismic). Two classes of Sequential Monte Carlo (SMC)¿¿?based multitarget algorithms are commonly used: Particle filter (PF)¿¿?based algorithms; and Markov Chain Monte Carlo (MCMC)¿¿?based algorithms. MHT is particularly effective in dense multitarget settings and in highly cluttered environments. The chapter discusses the current nonlinear filtering algorithms. Suitable filters can be selected for the track filter given the nature and complexity of the tracking problem. A collection of dynamic and measurement models commonly used in filters are presented for a wide variety of tracking applications. The chapter presents a detailed hybrid¿¿?state derivation of the track¿¿?oriented MHT equations following the formulation by Kurien with some minor modifications.

  • Skill Acquisition and Self-Improvement for Environmental Change Adaptation of Mobile Robot

    Learning and development are essential processes for an animat to adapt itself to environmental changes so as to accomplish a given task. This paper proposes a single mechanism for learning and self-improvement that results in learning curves similar to the "U-shape" phenomena observed in several psychological experiments concerning the human learning process such as in language acquisition. The basic idea is that (1) the animat monitors its success rate in goal achievement so as to perceive environmental changes instead of relying on signals from a teacher, and (2) in order to reuse acquired knowledge and accelerate reinforcement learning, the animat does not memorize the action values but transfers only the learned policy. The resultant policy (a state transition map where transitions indicate the best actions) may not be optimal in any given environment but it may be able to better handle differences between environments. We apply this model to a mobile robot navigation problem for which the task is to reach the target while avoiding obstacles by means of uninterpreted sonar and visual information. Our experimental results demonstrate the validity of the model.

  • Global localization and topological map-learning for robot navigation

    This paper describes a navigation system implemented on a real mobile robot. Using simple sonar and visual sensors, it makes possible the autonomous construction of a dense topological map representing the environment. At any time during the mapping process, this system is able to globally localize the robot, i.e. to estimate the robot's position even if the robot is passively moved from one place to another within the mapped area. This is achieved using algorithms inspired by Hidden Markov Models adapted to the on-line building of the map. Advantages and drawbacks of the system are discussed, along with its potential implications for the understanding of biological navigation systems

  • Towards a theory of how bats navigate through foliage

    In this paper we study echolocation by spectral analysis as a possible mechanism used by bats to navigate through their natural environment. We simulate the echo signals received by a bat inspired sonar system confronted with realistic reflectors, i.e. a large number of closely spaced scatterers. We propose a method to localize such natural reflectors on the basis of the time-frequency representation of the returned echo that is calculated by the bat's cochlea. The sonar system is simplified into a piston emitter and two piston receivers, of which the latter can be rotated. The method proposed reconstructs the environment by comparing the returned echoes with predefined templates corresponding with echoes from different angles. We show that the overlap between members of this set of templates can be used as a measure of their accuracy for localization purposes. This method is then applied to both monaural and binaural sonar systems and is shown to allow useful navigation behaviour. The problem of ghost images, i.e. erroneous interpretations of ambiguous position estimates, is shown to be inherent to single measurement based decisions. Finally, we show how active control of the ear configuration allows binaural sonar systems to eliminate ghost images by combining the resuits from a sequence of measurements, each corresponding with a well chosen ear configuration. Despite the description in this paper being restricted to the two-dimensional situation, this is not essential and we discuss how the mechanism described can be straightforwardly extended to the full 3D case.

  • Matrix CRLB Scaling Due to Measurements of Uncertain Origin

    In many estimation situations, measurements are of uncertain origin. This is best exemplified by the target-tracking situation in which at each scan (of a radar, sonar, or electro-optical sensor), a number of measurements are obtained, and it is not known which, if any, of these is target originated. The source of extraneous measurements can be false alarms-especially in low- SNR situations that force the detector at the end of the signal processing chain to operate with a reduced threshold-or spurious targets. In several earlier papers, the surprising observation was made that the Cramér-Rao lower bound (CRLB) for the estimation of a fixed parameter vector (e.g., initial position and velocity) that characterizes the target motion, for the special case of multidimensional measurements in the presence of additive white Gaussian noise, is simply a multiple of that for the case with no uncertainty. That is, there is a scalar information-reduction factor; this is particularly useful as it allows comparison in terms of a scalar. In this paper, we explore this result to determine how wide the class of such problems is. It turns out to include many non-Gaussian situations. Simulations corroborate the analysis.
