Abstract

Nowadays, the use of digital instruments in industries is rapidly increasing. This is because digital instruments are usually more accurate than the analogue instruments, and easier to be read as they are hooked up with an LCD display. Since users can directly obtain the readings in digit form, these digital instruments are free from parallax and approximation errors. In process control industry, a monitoring system is very important system in the process of supervision about the state of the process. Mostly, the process parameters can be measured by using digital instrument, the obtained results will be recorded. In this project, an LCD display data capture system using optical character recognition (OCR) approach has been implemented. A Graphic User Interface (GUI) for the system by using MATLAB software is achieved. The system is interfaced with an IP webcam to capture the video frames from the LCD display. In this project, a smartphone is used as an IP webcam. Then, the system will pre-process all the video frames, the pre-processed video frames are then proceeded to the next step, which is data extraction using neural network and the extracted as data will be logged out to Microsoft Excel spreadsheet. 90% accuracy have been achieved by the system for 50 sample images of different LCD display. Finally, the system can be concluded that it is able to contribute as data extraction system for industrial purpose.
