TWO-DIMENSIONS POSITION ENCODED AND RECOGNITION TECHNOLOGY
Digital levels is typical product which using image processing to compete position measurement, but the encoded in digital levels is one-dimension position encoded. A surface positioning method based on two-dimension encoded recognition is presented. The structure of pen-type coding image detection system is provided. In order to complete position encoding the non-continuous code area coding and incremental coding methods are put forward and analyzed. In this system, we get position coordinates by the process of coding image. The image process steps and recognition method are discussed. This method can be applied to the development of interactive electronic whiteboard and computer input device.
