SCAN

Geo – Georeference the data to a cartesian coordinate system where (0,0,0) is Earth centre.

Scan/Burst/Timed – Scan mode will capture data continuously. Burst mode will capture only when the “snap” button is pressed. Burst mode will also capture approximately 2x the number of points per “snap” compared to scanning in High Rate mode. Timed is as per Burst mode BUT the frame is automatically captured every 2 seconds.

Filter – Turns noise filtering on or off. Optionally highlight the points bright green which will be filtered out of the scan with the Vis mode.

Display – Toggles high contrast display mode for outdoor or bright light settings.

Auto View – Turns Scan Auto View On/Off. When on, the scan is displayed automatically on completion of scan but the view world positioning data is reset. When off, the scan is not displayed but world positioning data is maintained.

Exposure – Sets the camera exposure for the Scan to Fixed or Auto.
