ABSTRACT
This thesis dissertation discusses research in the automation of reading a energy meter. The hardware required is a wireless camera pointed at the meter to be read. This meter can be a water, electricity or gas meter. After the wireless camera collects the image from the utility meter it transmits the image to a computer through a receiver. The computer analyzes the image with pattern recognition technology to obtain the numbers. We use image processing techniques in this thesis, including image preprocessing, image segmentation (Otsu threshold method),and number recognition. Finally we create a graphical user interface using Visual Basic. In order to realize this goal we use a method called pattern recognition in this thesis. Pattern recognition is a technology which includes face, voice, and fingerprint recognition. Today it is being applied to more and more fields than ever before, and we use number recognition in this thesis. Number recognition has been widely used in identification, asset management, highway toll management, access management, and pet management just to name a few.
