Capturing measuring points with a sensor

When capturing measuring points with a sensor, various sensor types are available
in the metrology sector. A distinction is made between tactile and optical sensors.
Which of two is used depends on the measuring task.
When selecting the appropriate sensor, the following criteria need to be
considered:
Properties of the measured object (e.g. surface structure, compliance)
Size and arrangement of the features to be measured (e.g. accessibility, form)
Required measuring accuracy
Economic efficiency and available measuring time
If the QUADRA-CHEK 3000 VED software option is activated on the product, the
product supports the use of a VED sensor (optical sensor). A VED sensor is a USB
camera or network camera connected to the product.
Optical sensors are particularly well suited for use in the following cases:
Small features to be measured
Large number of measuring points
Short measuring times
Compliant objects to be measured
When capturing measuring points with a VED sensor, the live image from the
connected camera is displayed in the workspace. The measuring points are
captured in the live image by using VED measuring tools.
For this purpose, the measuring plate is traversed to position the measured object
in such a way that the live image shows the feature to be measured on the object.
The operator positions a VED measuring tool above the measured object in the live
image.
