Usually, neither Freestyle 2 nor SCENE require artificial targets, also called markers, to produce scans that can be registered. But there are situations where markers can be helpful, for example when the area you are scanning does not have well defined planes, or if you want to register a Freestyle 2 scan with a FARO Focus Scan.
A set of 20 unique markers is included with the Freestyle 2 kit. Markers for printing can be downloaded below:
TIP: To ensure accuracy, always use a laser printer to print targets.
Guidelines for Using Markers
- The markers are numbered. Ensure that every marker plate in the scan has a unique number. Do not use plates with duplicate numbers.
- When using self-printed markers, place them only on flat surfaces.
- Do not move the markers until the scan project is finished. Especially outdoors, you can place weights (e.g., stones) on the corners of the markers. The weights must not cover or cast a shadow on the pattern on the marker plate.
- The pattern must be easily and clearly visible.
- Position the markers in an irregular pattern. Do not position symmetrically.
- Place in different distances to the object. Avoid a linear alignment.
- Ideally, a marker plate should be captured at least twice in a scan.
