The research of wheelchair tracking and the security identification

In order to enhance the wheelchair users' security, a wheelchair identification and tracking system is proposed in this paper. This system can be used in hospital to avoid the accidents of serious patients or old people. Based on the space relative constraint, it can provide accurate result for wheelchair position detection. One statistics method is applied to recognize whether have someone behind the wheelchair or not. The union image tracking technique makes the image tracking localization of the moving wheelchair. This method is suitable in the hospital on the hospital ward and the aisle. Based on the experimental result, the calculating method obtains the satisfying achievement and accuracy.
