Digitization at ‘Clepsydra’

1. 3D colour laser scanner for movable objects which captures simultaneously geometry, colour and reflectivity information from the object’s surface. The system provides the highest scanning resolution that is available today and the digitised object reflect the most accurate registration of geometry and colour information as they are collected using the same sampling beam. The ambient light does not affect the scanning process to illuminate the object and thus none of the effects (dark areas, flares, etc ) of ambient lighting are visible on the object.

2. 3D laser scanner for movable objects based a multiple axis articulated measuring arm with six degrees of freedom and 2 Sigma Single Point accuracy of ± 0.076 mm. The system is capable to capture 20.000 points per second. The scanner is equipped with two digital cameras placed on either side of the scanning head so that data capturing is not interrupted even in situations were one camera is blocked.

3. Automated 3D colour digitisation system for movable objects that is based on professional photographic lighting equipment, digital cameras and a turn table controlled by special software. The digitisation results of the system are characterised by their low complexity applicable for internet publication and by their high colour information realism. The automated scanning procedure allows the system to be used for mass object digitisation.

4. 3D color digitisation system for movable objects which is based on digital cameras and special software. The system operates in combination with the previous one in order to expand its application field to larger objects that are not possible to be placed on the turn table due to their weight or shape.

5. 3D digital camera based on structured light technique. In order to completely reconstruct an object multiple photos from different viewpoints are required. The technique is applicable to objects that cannot be moved.

6. A fully portable 3D colour range laser scanner specifically designed for the rapid acquisition of high quality and spatially correct 3D points clouds via LIDAR technology. It provides a scanning range to over 1000 meters with a capturing accuracy of 7mm in 100m distance and a 360 x 360 degrees field of view. A highly applicable system for the digitisation of monuments, urban areas, etc.

7. Special software for photo-based modelling and measuring. In practice several photographs of a given monument are taken from a number of different camera angles and a number of common features, which can take the form of points, lines or polygons, are marked by the software. Through a process of interpolation these marked points an accurate 3D model is created which can be later on moved to CAD or 3D modelling software.

8. Two dimensional colour scanner designed for the digitisation of books, documents, etc. It unites a state-of-the-art scan lens, high-quality CCD image sensors and white LED light which is clustered in a mobile light strip that follows the scan. It satisfies the most individual of requirements as it can scan at a resolution of 400 dpi on A1.

9. Colour film and photographic transparencies scanners that support multiple format films such as 35mm, E6, C-41. The scanning resolution can be up to 4000 dpi with 12 bits per colour channel. In practice a 35mm film frame can be scanned at 5619 x 3831 pixels producing a file size of 65MB.

10. Professional colour film recorder that produces professional-quality 35mm slides at 4,000 lines of resolution, typically in less than two minutes per slide. It supports a variety of both positive and negative 35mm films, including E6, C-41 and Polaroid instant 35mm films

11. Digital microfilm scanner that provides extensive microfilm search and retrieval; combining sophisticated image adjustment features, desktop editing, cleaning and document printing at 400 dpi. It scans a frame in less than 8 seconds. It offers print border and background erasure and masking for editing the unwanted information.

12. Digital SLR cameras with resolution up to 40MPixels. Photoshooting is performed in a photographic studio with professional lighting. A large set of special lenses are provided to enhance capturing.

13. Multispectral digital video camera (3CCD/IR) with a 7.5 frames per second and a resolution of 1392 x 1040 pixels per colour sensor. It offers a method to monitor erosion in monuments and also to reveal underdrawings in paintings, older compositions of a picture, hidden signatures as well as retouched regions of works of art without causing any damage to them.

14. Digitisation table systems for demanding CAD, GIS and graphic arts applications. They offer an active area of 457 x 610 mm.

15. Flatbed scanner with fixed CCD and main lens that provide true auto-focus calibration to ensure sharpness. The ultra-high optical resolution of 3048 dpi offers pre-press enlargements from 35mm transparencies to over A4, and inkjet and RGB media output well above the A3 size. The system allows a 42 bits output for higher specifications applications that require the maximum tonal range for further manipulation.
