For dark parts, it would also be possible to play with parameters of the scan like the texture brightness. The solution is then to use a matte spray (for transparent or shiny parts) or positioning targets (for parts with a lack of texture or geometry for example). This object must be immobile, include a minimum of geometry or texture, be uniformly lit and installed in a large enough space to be able to scan it as a whole.Īs with any scanner, some objects such as dark, transparent or shiny parts can be difficult to scan. However, an important step that is common to all 3D scanners is to make sure that the object to be scanned is compatible and, if necessary, to prepare it. Operations that can also be done from a computer if necessary.
The only steps required for the first use are to turn on the Leo with the ON/OFF button, connect it to the Internet, accept the user license and activate the product from the touch screen. Setting up the Artec Leo is relatively easy as it is ready to use right out of the box. The Leo 3D scanner offers a sleek and modernized design compared to its predecessors 2. On the processor side, the scanner is equipped with the NVIDIA Jetson TX1 platform, including various sensors (accelerometer, gyroscope and compass), allowing the Leo to position itself in space. The left lens is equipped with 12 LEDs and includes two cameras, one that recovers the distortion of the grid and the other that takes color pictures to obtain the texture of the object. The right lens projects a grid on the object with a laser, in an invisible light spectrum, like a structured light scanner. When we look at the scanner more closely, we can see the presence of two lenses on the front. This is inclinable in order to facilitate reading during the digitalization phases, with the possibility, for example, of digitalizing with the scanner upside down if need be. Visually, the big difference comes from the addition of a large 5.5″ inch semi-HD touch screen on the front. This weight increase is mainly due to the integrated battery. With slightly larger dimensions of 231 × 162 × 230 mm (9.1” x 6.4” x 9.1”) compared to the Eva and Spider, the weight of the Leo is almost tripled to 2.6kg or 5.7lbs (compared to 0.9kg/2lbs for the Eva and 0.8kg/1.8lbs for the Spider). This version has been revamped and modernized in contrast to its predecessors. The first thing you notice when you unpack the Leo is its sleek, new design compared to other models on the market. The Artec Leo comes in a protective case that includes the scanner’s power cables, a removable battery and the user’s manual.
