High-Speed 3D Scanning for Large Parts

Metrology service provider EXACT METROLOGY is offering the Hexagon Metrology Intelligence RS-Squared area scanner, a 3D scanner that's compatible with all current-generation Absolute Arm 7-axis systems, and allows users to perform high-speed scans of simple shapes and surfaces. It is best suited to the scanning of large parts with lower detail requirements, such as automotive parts.

The Absolute Arm 7-axis system delivers tactile probing and laser scanning in an ergonomic package. It is recommended for portable measurement applications, with an articulating arm that offers ease of movement and ease of measurement. 

RS-Squared is a white-light scanner that uses the Absolute Arm system to position large square ‘tiles’ of 3D scan data. This removes the need for time-consuming application of reference markers or spray, or complex mechanical processes, such as fringe projection that requires a stable environment.

Up to four data tiles are captured every second which, combined with minimal set-up time, creates a scanning system capable of generating point cloud data in very little time. As with other Absolute Arm scanners, the RS-Squared can be removed and remounted easily, without time-consuming recalibration due to its repeatable mounting system.

Additional features include an extra-large scan ‘tile’ (300x300 mm), providing a fast scanning solution by permitting coverage of a larger area. Furthermore, the RS-Squared area scanner is so fast that a surface that usually would take one hour to scan, can be digitalized now in 10 minutes. The retained touch probe functionality of the Absolute Arm ensures that high-detail geometric features can be captured at any time by removing the scanner from the arm and connecting it to a probe.

Data feedback and settings adjustment at the point of measurement is built into the Absolute Arm 7-axis through its OLED on-wrist display, and the RS-Squared scanner profiles are selectable without putting down the scanner. 

The full scanning system accuracy of the RS-Squared area scanner and Absolute Arm 7-axis system is certified according to ISO 10360-8 Annex D.
