The line (or arc) of measurement is specified using ActivView's subtool AVTViewROI.

You can align ROIs automatically to moving parts with the help of ActivAlignment.

If high-accuracy 3D measurements are required, ActivMeasure should be combined with ActivGeoCalib; if all measurements take place at the same distance to the camera, ActivView's subtool ActivViewCalibration might be sufficient.

ActivDataView displays the measurement results in a spreadsheet. You can evaluate these results in ActivDecision by formulating conditions the results have to meet in order to be "okay". Results and evaluations can then be written to a log file using ActivFile, output via the serial interface using ActivSerial, or output to digital I/O boards via ActivDigitalIO.
