| Abstract(in English) | We propose an image-based surveillance robot which can detect abnormalities, such as unattended baggage Compared to surveillance systems with fixed cameras surveillance robots can monitor a large area with fewer cameras. However, the robots experience difficulties in abnormality detection because of intervals between captured images To detect abnormalities from these images a method for accurate image position adjustment and abnormality detection tolerant to these intervals is required. We propose i) a method for the image position adjustment based on perspective projection and ii) nonparametric abnormality detection based on posterior probability of sample patterns. These methods have been tested using a movable camera within an office environment. The system can adjust image positions containing 10～20cm error relative to the surveillance subjects at l～2m distance from the camera and correctly detect abnormalities in a scene with complex textures where former methods, such as background subtraction and subspace methods, fail. |
