Surface Measurement

Surface measurement involves capturing a sequence of laser profiles, optionally identifying discrete objects, and measuring properties of the surface or the objects, such as the volume of the object or the height at a certain position of the object. All volumetric tools have the ability to operate either on the entire surface or the full object, or within a region of interest at a certain position in relation to the surface or an object.

Multiple measurements can be performed on the entire surface or each discrete object, limited only by the available CPU resources.

The frame of reference for the coordinate system of the detected object can be set to Sensor or Part in the Part Detection panel (Part Detection). This setting determines what coordinate system the region of interest for a measurement is positioned in, as well as the coordinate reference used to output measurement values.

For example, if you need to measure the average height in a certain location relative to the sensor's field of view regardless of the objects passing under the sensor, the frame of reference should be set to Sensor. This is typical in applications where a wide web of material is continuously scanned, such as paper, rubber, fabrics, etc. If on the other hand you need to measure the average height in a certain location of a scanned object, the frame of reference should be set to Part. This is typical in applications where discrete objects pass under the sensor and specific locations on the objects need to be inspected.
