As you may know, the Go!SCAN 3D can generate the complete 3D surface of an object without using a single positioning target (marker). A white light pattern is projected onto the object, and two cameras record the distortion of the pattern on the part over the entire light pattern. The geometry information is then used to build the surface in real-time.
However, when an object’s area doesn’t provide enough positioning information, targets should be added in order to allow the acquisition. Targets help the tracking of the sensor since they lock some degree of freedom that could cause slippage problems due to an object’s lack of positioning information in a specific area. Adding targets will always optimize the accuracy of the resulting mesh and when accuracy is crucial for the user, the “Target Required” checkbox should be activated when the Positioning node is activated in the tree view.
Now, with the arrival of the texture camera within the new generation of Go!SCAN 3D, the Intelligent Hybrid Positioning gets even smarter! The sensor is now able to detect available information within the color and it greatly improves geometry tracking. It’s as if the software was putting virtual targets for you! The greater the differentiation in color on the object, the better this new functionality will work.
The “Use natural features” option can be activated by checking the option box when the Positioning node is selected in the tree view. Once the software sees recognizable information within color, “Naturals feature targets” will be recorded and named under the Positioning node. These will turn red when used and remain blue otherwise. The virtual targets even enable scan resuming if you lost tracking at some point during the scan, which make this new feature an even more wonderful tool.
The Intelligent Hybrid Positioning feature always uses all available information to create positioning while ensuring that sufficient data is available to guarantee accuracy. The built-in intelligence will also prevent the acquisition of inaccurately positioned frames and is definitely the best friend of the scanner tracking system, which has been greatly improved with color detection and all the information that comes with it.
