摘要：Laser scanners are used more and more as instruments for various tasks in cultural heritage conservation. Especially old buildings and archaeological sites are relevant to offer a variety of applications e.g. the surveying of static or simply the visualization and precise modelling for data archiving purposes. The developed IMAGER 5003 is a state-of-the-art, high precision, high speed laser scanner, which provides accurate measurements. The IMAGER 5003 measures range and intensity images at the same time, with a one to one correspondence between these both images with respect to the angles: The range image generates geometric dimensions of the environmental scenes, whereas the reflectance image generates a photographic like impression of the scanned environment which is used for feature extraction, visual inspection, object segmentation, and surface classification. For visualisation tasks the scan data can be combined with colour information: For this purpose either a special high resolution line scan camera – developed by the German Aerospace – or a standard digital array camera can be used. This paper introduces from a practical point of view into visualization and modelling techniques by using the laser scanner IMAGER 5003. The paper describes features and methods of the system, and shows up two applications in the field of cultural heritage conservation and civil engineering
