Digitalization of solitary objects is of great importance for preservation of cultural heritage, development of virtual museums and galleries, digital cabinet, scanning engineering components, or interior furnishings. Created 3D models or object panoramas can also be used as a foundation for restoration works, replica and clones creation, and they also provide the most reliable recording of the object in case of destruction or loss.
In case solitary objects, we collect data primarily using Close-Range photogrammetry. The principle of this method is based on determining relative location of cameras to scanned object, calculating dense cloud of points, mesh and its texture.
We use Infrared scanner to define model scale with the accuracy of tenth of a millimeter. It is a contact scanner that works on the principle of coordinate measuring machine. It measures points outside the object to avoid disruption of the object’s surface.
Object panorama is a simpler form of visualization of object than 3D model, as it provides 2D images. The downside is that we cannot make accurate measurements using the data, neither achieve unlimited model rotation. The advantages include speed and ease of capturing images, and receiving images in high resolution that can allow to zoom in on particular detail. Object panorama sample.
Cutting edge technology
We use cutting edge technology of Close-Range photogrammetry, and panoramic imagery. We use APS-C and Full-frame sensors from 16 to 50 Mpix and Canon and Olympus high-light lenses. The advantage of these technologies is that they represent contactless scanning methods. We scan solitary objects with dimensions of 2 x 2 x 1.5 m in our studio. We also have mobile diffuse tent and flash technology for more demanding task at our disposal. We have developed special working procedures for various surface types (plastic, wood, stone, metals, fabrics). We can create metrically accurate 3D models using a combination of photogrammetric scanning and contact scanning.
