摘要：We have developed a new inexpensive PC-based photogrammetry system, by which we can accomplish rapidly in real time all the measurement and analysis, including photographing, 3D measurement, plotting, ortho-image creation etc. We have just started to sell in Japan. We can do this on the actual survey site, using simply an ordinary digital camera and a lap top computer. And if necessary, we can confirm or measure afterwards the resulted images in great detail and precision with a 3D display. As an example of its actual application, we experimented our system on Parthenon in Athens. We took its pictures by a digital camera loaded with a calibrated zoom lens (i.e. the lens for which camera-parameter has already been pre-installed in computer), visualized it in 3 dimensions and produced the final plan. The result was quite satisfactory. The system also proved itself to be very useful for us to cooperate with the architects (or the person in charge of National Cultural Heritage Preservation, for example), exchanging information and making decision as to the object extent or various other points of importance on the very site itself. With this system we could also obtain a very positive result in 3D measurement of a wall relief or a statue in ruins or excavations
