A vision-based pet robot interaction

We developed a new vision-based interface that can detect the human motion and control a pet robot interaction system. This vision-based interface is composed of the "Motion Processor (MP)" and the "Region Of Interest (ROI)". The MP is a new image input device. The MP can exclude background part and capture only the object's shape, motion and depth information in real time. The ROI is a concept in order to distinguish objects in a captured image. For detecting the ROI, the proposed method used depth information of the captured image and offered a fast and robust searching method. It enables the MP to sense a variety of object's shapes, motions, positions and so on. Therefore, our vision-based interface using the MP with the ROI can easily recognize object's motions as effective computer eyes. The user can interact with the pet robot (constructed by LEGO MINDSTORMS™) using this vision-based interface.
