Targets and Scanning

Targets are physical objects that you set up on site that scanning software uses to tie together multiple scans. The process of tying together scans is called “registration.” If you have set up your targets correctly, the software will be able to register your scans together with relative ease. However, if targets are placed improperly, a lot of manual registration will be required. Manual registration is incredibly time consuming, and it is absolutely worth it to take extra time in the field to properly set up targets.

Setting Up Targets

When setting up targets, you need to keep in mind that 3 targets minimum are required to register two scans together. This means each consecutive scan needs to have 3 targets in common with the previous scan. Up to five targets are recommended as a safety net; however having too many targets is time consuming to set up and will take the registration software more time to process.

When setting up targets, take the following factors into account. Be aware that they will change per manufacturer.

1. Resolution: The resolution your scanner is set to will affect how far you can place your target. For example, for a FARO scanner, at 1/4 in, the target can be up to 60 feet from the scanner; at 1/8th in it can be up to 30ft away.
2. Distance: As mentioned above, targets can only be so far away from the scanner and still provide accurate registration. Keep in mind that what are listed above are maximums and could be significantly less, for example, there is a lot of dust and moisture in the space.
3. Environment: Factors such as sun, dust and moisture can have an effect on how accurately targets are captured.
4. Size of target: Smaller targets must be placed closer to the scanner. Targets will typically come with instructions about distances from the scanner.
5. Any vibration: If you are in a room with vibration or very heavy air flow, such as a mechanical space, be aware that your targets may move and take extra precautions to secure them.
