Abstract: A method of geometric calibration of charge-coupled device (CCD) vision systems for metric measurement has been developed. The method does not require a special calibration facility or accurately surveyed three-dimensional ...

Abstract: A knowledge-based system has been developed to help inexperienced users make measurements from stereo video images. The purpose of the system is to automate much of the routine functions and decision making in photogrammetric ...

Abstract: An attempt was made to investigate the state-of-the-art use of a digital and near real-time system to monitor monuments and historical sites by integrating semiautomated PC-based computer vision and stereo-photogrammetric ...

Abstract: Air voids in an asphalt concrete pavement highly influence its performance. Careful consideration of void requirements in compacted bituminous mixtures is more important than stability consideration, since the latter is ...

Abstract: An attempt to investigate the potential capabilities and accuracy of the PC-based stereovision system in quantification of pavement rut depth was performed. This process was demonstrated using three rutted sections of ...
