Positioning Targets for 3D Scanning

Positioning targets are applied before 3D scanning, either on the object or around its immediate surroundings. They are essential in creating a reference point for the 3D scanner, and the key to portability and dynamic referencing.

The targets enable users to register all the different camera frames for the 3D data sets acquired by the scanner. Targets usually have a simple geometric shape, often a circle, and are specifically designed for easy detection by the 3D scanner’s optical components. After the scanner detects targets individually, the next step determines their relative position.  A target data set with a minimum of three targets is used to position the scanning frame. As the scanner is moved around the part, new targets are detected and registered on the global positioning model.
