Development of a Probabilistic Sensor Model for a 3D Imaging System

The use of high frame-rate 3D imaging systems for construction equipment control is part of a broader research effort at the National Institute of Standards and Technology investigating innovative technologies for automated construction, performance and evaluation of 3D imaging systems, and construction object recognition and tracking. A probabilistic measurement model is desired for these imaging systems to better understand and describe the instrument performance, and to create synthetic data sets for algorithm development, training and testing. The initial development of a probabilistic sensor model and 3D image simulator based on an open-source graphics package is presented in this paper.
