Abstract In order to realize an application of camera-based character recognition, a character recognition technique which is (1) ready for real-time processing, (2) robust to perspective distortion, and (3) free from layout constraints, is required. In this paper, a camera-based character recognition method which satisfy the three requirements is proposed. As a result of a combination of simple but efficient techniques, the proposed method enables us to execute camera-based character recognition in real-time even on a laptop PC with a cheap web camera. Real-time processing is realized using a principle of geometric invariants in a different manner than usual. This drastically reduced computational cost and achieved fast recognition of around 200 to 250 characters per second on a server.
