EasyGauge is a second-generation measurement and dimension control library for use in gauging applications. By relying on proven sub-pixel edge detection and least squares fitting algorithms, it allows determining the position, orientation, curvature, size… 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 adjustment of parallel sides, thus providing means of measuring thickness of flat or bent objects, as well as precise location of corners.

Advanced 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.
