SYSTEM FOR ASSESSMENT OF SAFETY LEVEL AT CONSTRUCTION SITE BASED ON COMPUTER VISION

摘要

According to embodiments of the present invention, an image-based construction site safety level evaluation system includes: an image processing unit which identifies equipment objects and worker objects among the objects extracted from construction site images; a first fuzzy variable calculation unit which calculates a worker-equipment distance from each worker object to each equipment object for each object; a second fuzzy variable calculation unit which calculates a worker density of other workers for each worker object; and a fuzzy inference unit which calculates the safety level of each worker object through fuzzy calculation and reverse fuzzy calculation according to membership functions corresponding to the worker-equipment distance and the worker density and a certain fuzzy inference theory.
