Application of Image Processing to Detecion of Workers Around Heavy Equipment

This paper describes the application of machine vision technology to prevention of collision accidents with heavy equipment such as hydraulic excavators and cranes. The images of the back side of heavy equipment with cameras which can take a picture with 180 degree shooting angle were captured and the worker was detected by developed color image processing algorism. A laser range finder and an orientation sensor were used to calculation of the distance from heavy equipment to worker who is detected from captured image.
