Research of Image Acquisition and Processing System of the Flow Meter Verification Equipment Based on Embedded Linux System

Abstract:

Aiming at the requirement of technique improvement for the flow meter verification equipment, the image acquisition and processing technology is combined with the embedded Linux system for obtaining the reading value of the verifying flow meter. A low-cost and moderate function image acquisition and processing embedded system was designed. The system runs on the ARM9 which is embedded with Linux operation system. It can realize the image acquisition of the reading value of the meter, image preprocessing, character positioning, segmentation and recognition based on OpenCV advanced programming, and then display the recognized data results. The research of our project may have a certain reference value for the application and exploring of the image acquisition and processing based on embedded systems in the instrument application.
