There is a great challenge that a mobile robot reliably and continuously tracks a specific person in indoor environments. In this paper, a novel method is presented, which can effectively recognize and reliably track a target person based on mobile robot vision. Gabor wavelet and hidden Markov model (HMM) are firstly employed for identifying the target person. In order to effectively track the specific...
A networked mobile robot in large networks such as Internet often operates under supervisory control and the discrete commands and decisions from the remote operators normally depend on the feedback scene information. Therefore it must be tolerate of the significant and unpredicted time latency that might mislead the robot for time and scene-dependent operations. A series of strategies are presented...
A probabilistic approach is proposed for Simultaneous robot Localization and Person-Tracking using Rao-Blackwellised particle filters (RBPF). Such filters represent posteriors over the person location by a mixture of Kalman Filters, where each is conditioned on a sample of robot pose. Furthermore, information collected via multi-modal sensors is utilized in the RBPFs framework to improve the performance...
People tracking and localization in situations with coexisting service robots is a challenging task due to the non-rigid nature of human body, complex background and frequent occlusions among people and robots. A multi-view approach is proposed to people-tracking and localization whilst the robotpsilas capability of perceiving environment is utilized. Initiated by person detection, tracking within...
The ability to detect and follow a specific person is considered to be a key prerequisite of service mobile robots in indoor environments. A novel vision-based tracking and following method for a mobile robot is proposed, which combines the clothes color features of the person's upper body and the contour of the head-shoulder. Horizontal-Projecting Probability Histogram (HPPH) of torso based on particular...
