The research topics include moving object detection, image feature detection and description, and robot navigation in unknown and dynamic environments. The aim of this project is to develop real-time vision-based SLAMMOT algorithms for intelligent mobile robots, providing the robots with suitable localization and mapping competence in unknown and dynamic environments in order to perform the navigation tasks. This project will be performed in two years. In the first year, a novel moving object detection algorithm as well as a modified image feature detection and description procedure are proposed for a hand-held camera or a mobile robot in order to perform localization and mapping in unknown and dynamic environments. The SLAMMOT is implemented by utilizing an extended Kalman filter (EKF) for estimation of system states. Therefore, the system with unknown inputs will be discussed and the performance of EKF will be analyzed. In the second year, the concept of sparse extended information filter (SEIF) is applied to design the SLAMMOT algorithm for mobile robots. Integrated with a local map management strategy, the SLAMMOT algorithm will be able to perform the tasks of localization and mapping in long-distance and large-area environments. Two real-time vision-based robot SLAMMOT algorithms will be implemented, one based on EKF and the other on SEIF, and be further applied on robot localization and mapping in unknown and dynamic environments. The developed algorithms will be integrated with real robot systems, and furthermore the integrated system will be empirically validated based on experiments to evaluate the practical usage of the developed algorithms.
