Abstract :
The decoding of barcode staff with digital level is the key technology to realize the automatic reading of digital level. According to coding principle that different width of bar code represents different measurement attitude, the relationship of sampling value of two sinusoidal signals and position on barcode staff was researched. In this paper, using sinusoidal image breadth matching and geometrical position, we discuss a new decoding method for barcode staff of digital level and give the calculation formula. With the design of barcode staff based on appropriate parameters signs, the experiment result indicates the feasibility of the decoding method, which will offer important theoretical foundation for the study of digital level.
