9 Glossary
The following definitions are in the context of the KMR video metrology systems. Some terms might have additional meanings. A
accuracy
The maximum error that the system will produce when measuring a true standard.
axis
A direction that enables movement and along which dimensions can be measured. In KMR systems, the X-axis is horizontal from left to right, and the Y-axis is from front to back, and the Z-axis is from bottom to top. B
blooming
A condition where the parts of the video image are distorted by oversaturated bright regions, making illuminated regions appear larger than they really are. C
CAD file
See Computer-Aided Design.
CMOS
See Complementary Metal Oxide Semiconductor.
Complementary Metal Oxide Semiconductor
CMOS cameras are a type of image capture device that utilize an image sensor to register visible light as an electronic signal. These types of cameras do not use photochemical film to capture images or video. Instead, the electronic signal is recorded to an internal memory or a remotely connected device.
Computer-Aided Design file (CAD)
The .cad file extension is used for a 3D graphics file format, which is often associated with CAD (computer aided design) projects. These .cad files contain digital 2D and 3D graphics. D
detent
Magnification can be set by turning the knurled adjustment in front of the zoom optics to one of its six positions.
distortion
Optical image distortion at the CMOS sensor across the maximum field of view. Expressed in percent for the dimensional error along one axis divided by the true dimension.
