Artec Studio 8.0^β

Most objects in our world are of a particular form and color. By default, our new feature tracker (for MHT scanners) uses both shape and texture information to align surfaces in real time. That means that whether you are scanning a geometry-poor object or a colorless object, you always receive great results!

It is almost impossible to find a more difficult object to scan than a plant. Thanks to our new feature tracker, however, potted plant here was scanned in less than 30 minutes, tracking both geometry and color!

This French armchair here was captured in less than one hour! Its rather humble friend, the stool, was also scanned using the new feature tracker with outstanding results!

In case the object has few geometrical features or is flat - say a ball or a wall - the tracker aligns incoming frames with the help of color info it finds on the surface.

In those rare cases when the object is neither rich in geometry, nor has color info, you can place the object in a texture-rich surrounding.
Take this ruler here. As all rulers, this object is rather flat. Because it is lying on a texture-rich floor however, the feature tracker will scan it easily, aligning incoming frames according to texture info. Simply delete the background afterwards when editing!

As we have scanned a ruler, let’s make the test and check accuracy. With the help of our measurement tools, we have marked 10 cm and 110 cm. You don’t have to be Einstein, to understand that in reality this distance is 100 cm. When measuring this distance on the scan, we see that in this case the linear error is about 0.06 mm on 1000 mm!

This quick test allows you to see that in this case we have achieved the error of 0.006%. Scanning accuracy is a lot higher though! The error here is due to the fact that we simply couldn’t place the markers more precisely.

If you want to be on the safe side for precision, but don’t have a texture-rich background near you, simply create one! How do you do that? By adding simple elements to the “featureless” area of the object: like drawing little Xs on the object itself or the area around it.

With the help of those little Xs we achieve the same accuracy as in the previous scan.
Thanks to the feature tracker, you can scan a great variety of objects – easy and fast!

If the object doesn’t offer enough texture data, but is rich in geometry - like a white sculpture, for example - the tracker uses unique geometrical features. Like in the example of the 15th century plaster statue below from the Pushkin Museum of Fine Arts in Moscow.
