Real Time Multi Target Capturing Using Partitioning in Robot Vision

Abstract— In this study, the authors design and implement a real time system as an autonomous robot–camera to capture many targets in the scene. The robot has only one camera, but it is capable of capturing more than one moving object through proper movement. The system uses Gaussian Filtering for motion detection and then performs partitioning to grab location of all targets in the scene. Due to partitioning, the scene has three major regions while each of which has different sub-regions. Based on the partitioning and position of all targets, the system might be in three states of unsafe state, safe state, and over-safe state. In each state regarding specific regions or sub-regions, the system picks appropriate movement not only to be capable of capturing all moving objects, but also to give equal chance of capturing to new targets entering to the scene from different direction. The system is tested in both of indoor and outdoor with different values for different parameters such as resolutions, fps (frame-per-second), minimum number of motion frames, and minimum areas of motion.
