摘要：The IoT(Internet of Things) technology basically requires identifying things that emit their identities The RFID (Radio-Frequency Identification) and Beacon technology are widely used as well as Image Code such as Bar-code and the QR code. The QR code has strenth in terms of cost since it can be cheaply printed. However, the QR code can only be used to recognize very close things. In this paper, we propose a new sign board that having a recognizable image code at a distance. An additional design issue is to provide a room for human recognizable contents. Our solution is to place code blocks on the boundary region of a rectangle shaped sign board. To dispose the code blocks on the boundary, we propose a line-shaped code. Then, we have tailored the design of the code by considering recognition performance. As a result of these consideration, we finally designed easy-recognizable 4-bit code blocks, 16 blocks. By adding the corner block to the designed code blocks, we created an 8-byte prototype for the boundary code. We also privide the method to detect the boundary code in a given input image. In our experimental results, the proposed sign board achieves 100% identification performance for given input images where the size of the sign board is 1/12 of the size of the image and the shooting angle is 60 degrees or less.
