Digital Sensors and Sensor Sysstems


Abstract: In view of the phenomenon of common infrared or laser scanning barcode in the market, a method of scanning barcode through the camera is proposed. The MB9F506 is used as the main control chip, whose kernel is the popular Cortex-M3 kernel. 30-megapixel digital image information of barcode is collected by using an OV7670 camera. This color image is changed into black and white image through binarization methods. The barcode is decoded by the barcode decoding algorithm. 4.3-inch liquid crystal display (LCD) screen with SSD1963 as the core chip is drive. Digital image of barcode and its value are respectively displayed on the LCD screen. The results prove that the system has some features such as simple operation, high stability, fast response, high technical content, widely application, and so on.


Keywords: ARM, Camera, Barcode.
