Laserscanning and Modelling Industrial and Architectural Applications (original) (raw)

Laserscanners are used more and more as surveying instruments for various applications. With the advance of high precision systems, capable of working in most real world environments under a variety of conditions, numerous applications have opened up. The developed IMAGER 5003 is a state-of-the-art, high precision, high speed laser scanner that provides accurate measurements. The IMAGER 5003 measures both, range and reflectance images at the same time. 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 identification, surface classification and documentation purposes. The laser sensor thus provides an active illumination, non-contact measurement of the environment. This is advantageous in many situations, where operator access is limited or poor ambient lighting exists. To realise surveying tasks in ...
