Real-time three-dimensional object detection and tracking in transportation

Flash LADAR (Laser Detection and Ranging) devices are one of the recent technology developments which allow rapid spatial data acquisition of scenes. Algorithms that can process and interpret the output of such enabling technologies into three-dimensional models have the potential to significantly improve work location and path of objects to make construction processes safer and more secure. Once people and equipment are detected and mapped into a three-dimensional computer model, their path can be analyzed and access to hazardous areas can be restricted. This paper presents experiments and results of a real-time three-dimensional modeling technique to detect static and moving objects within the field of view of a high-frame update rate laser range scanning device. Applications related to transportation and construction are specified.
