Technology

We aim to provide high quality 3D models of real objects as a cost efective alternative to laser range scanners and manually constructed models. The reconstructed models contain not only accurate geometric data but also reflectance data which allows the customer/user to view and re-illuminate the digitised objects in generic Virtual Reality applications.

Our software creates accurate surface models and high quality segmentation from volumetric data sets:

• Sub-grid accuracy
• No need for help from expert users
• Resulting surface data can be loaded/converted into standard visualisation packages
• Shapes can be reproduced (e.g. using manufacturing techniques such as stereo lithography)
• Measurements (e.g. area, volume, distance) are readily available.

Our sophisticated software creates accurate Computer Graphics models from image data. Features of the new technology include:

• INPUT: multiple digital camera images of the scene/object (no specialised equipment required)
• OUTPUT: Computer Graphics formats such as VRML, STL, MPEG, etc. Output mode/format and level of detail can be chosen to suit the particular application.
• Complete geometric model (can ’walk around’ object)
• Complete photometric colour model (user can change lighting)
• Performs well also on curved objects (sculptures etc.) including those with concavities/grooves
• Objects can be of arbitrary size
• Can handle multiple objects
• Output can be modified by the user to change shape and/or texture of the object or to animate the obtained model.
• Current limitations: complete modelling of glass and semi-transparent objects
