This book helps specially the construction managers and safety personnel who have been trying to keep the construction site safer. Nowadays, an innovative idea is emerging that “zero fatality” at the construction sites is possible. Throughout the history of the construction industry, globally, millions of fatalities and injuries have occurred at construction sites. Among the various causes of accidents, one of the major causes is unsafe site conditions; basically, this is due to inadequate traditional supervision. To improve upon the traditional supervision approach, this book developed a framework for construction safety visualization approach. In addition to this, a computer vision “Edge Detection Algorithm” was developed and tested to convert construction site still images into edges of the objects in the images. The framework development of this study uses computer vision, robot vision, image compression, pattern recognition, internet transmission, network communication, and image processing.
