Measurement targets are fundamental components of the photogrammetric measurement system. They are used for signaling measurement points. Depending on the application, they are available in different sizes and materials. Permanent targets (P) are applicable even in high temperatures, up to 150°C (Retro-reflective up to 65°C). Removable targets (R) are easy to remove from the workpiece after finishing the measurement. Reusable targets (U) can be used multiple times and save costs. Magnetic targets (M) offer easy application and removability as well as reusability on magnetic surfaces.
