EasyGauge is a cutting-edge measurement and dimension control library for use in gauging and metrology applications. By relying on proven sub-pixel edge detection and shape fitting algorithms, it allows determining the dimension, position, curvature, size, angle or diameter of manufactured parts with an excellent accuracy.

Robustness is ensured by powerful edge-point selection mechanisms that are intuitive and easy to tune, allowing measurement in cluttered images. In addition to these state-of-the-art features, EasyGauge also supports the automatic measurement of parallel sides, thus providing means of measuring the thickness of flat or bent objects, as well as the precise location of corners.

Advanced and automatic calibration
EasyGauge has advanced built-in calibration capabilities to transparently convert pixel measurements to physical units; this relieves the user of the need to convert coordinates. Non-square pixels and rotated coordinate axis are supported. EasyGauge also provides means to determine and correct perspective and optical distortion, with no performance loss.

Gauge grouping
EasyGauge supports grouping of the measurement gauges and lets these groups track the measured items in the image. These can freely translate and/or rotate while the probes are repositioned accordingly. Derived measurements such as distances between feature points can then be computed.

Linearity: 3 (1/15th of a pixel)
Model fitting: Translation 3-sigma static repeatability: 1 (1/50th of a pixel)
Linearity: 1.5 (1/30th of a pixel)
Size 3-sigma static repeatability: 1 (1/50th of a pixel)
3-sigma static repeatability: 1/100th of a degree
Linearity: 1/50th of a degree
