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.
