| Summary: | LED light are getting popular nowadays and they can be programmed to send out message. However, currently there is no application that is able to use an android phone to read and decode the message from the LED light source. The purpose of this project is to develop an android application that can read messages transmitted from a LED light source. This application is created on Android Studio. It uses Raptor Code algorithm to decode the messages from the LED light source. It also uses and open source Application Programming Interface (API) OpenCV to help find the message area from the images captured. When pointing the android phone with this application to light reflected from a LED light source, a message would be decoded and displayed. In conclusion, the application was completed but there were some limitations to it. Such limitation would be that the android version must be 5.0 and above. |
