Abstract: The multi-sensor technique is applied into the vision system of electronic pet called electronic dog, and a system architecture is proposed, which integrates the recreation and the security capabilities. The flowchart of the system is explained. The method based on first-order difference chain code image and structural pattern recognition theory are introduced. A novel head shape detection method is given. Simulation experimental results show this system gets better performance and has the value of market application.

Key words: pattern recognition, chain code, multi-sensor, multi-target recognition
