Whether unintended or not (e.g. when using a fisheye lens for security applications), distortions are an everyday occurence in image acquisition and these can lead to incorrect measurement results. To avoid these inaccuracies, MATRIX VISION offers help with the mvIMPACT calibration module. Thereby the module equalises scale, perspective or non-linear distortions easily.
Distortions are an everyday occurence in image acquisition and these can lead to incorrect measurement results. Even high quality lenses show distortions the eye cannot recognise. But these distortions are measureable.
With the mvIMPCT Calibration module these distortions are a thing of the past. This module extends mvIMPACT with the ability of an optimal image acquisition. Thereby the module equalises scale, perspective or non-linear distortions easily.
The calibration of the system takes place with a calibration grid held in front of the camera. mvIMPACT analyses this grid and calculates the transformation data automatically. The adjustment of the distortions can be achieved with an image transformation. After this transformation the user receives a corrected image which can be used with existing algorithms to get calibrated measurement results.
The calibration module also provides functions for coordinate transformations. The modules mvIMPACT Blob and mvIMPACT Measure use the coordinate transformation functions automatically to get calibrated measurement results.
In contrast to the general trend, increasing application complexity does not mean a loss of usability. The mvIMPACT Calibration module features easy handling during the identification of distortions.

You can evaluate mvIMPACT SDK for 30 days free of charge once. Afterwards, you will need a licence! If you are using a dongle for licensing mvIMPACT, you have to use the latest USB dongle in combination with the 64bit version!
Nightly builds are tested exemplarily and should be tested by oneself before use!
