Automatic LED lighting system using moving object detection by single camera

Abstract

Smart LED lighting systems have been interested and developed for spaces such as buildings, rooms, garages and marine. The light sensor and motion sensor to control the automatic brightness of LEDs are very effective for automatic LED control system. In this paper, we address an idea which replaces light sensors, motion sensors by a camera. Our system integrates image processing to control an illumination system based on LEDs for buildings, rooms and garages, assume that an array of LEDs is installed on the wall. Here, our system detects moving object using adaptive Gaussian mixture model (AGMM), estimates the mapped positions of objects using inverse perspective transformation and a dimmed LED, and calculate the brightness of image from only a single camera. We implemented our system using LED array board with AVR micro controller and verified that our system is effective for automatic LED control system in specific room. © Springer-Verlag Berlin Heidelberg 2014.
