SCD-0025-2DScanner Documentation

2DScanner is a Scorpion Camera Driver that turns one or more ordinary area scan cameras into a scanning device. It behaves like any other camera in Scorpion - you select it in the camera list, grab from it, and get one finished image back - but behind that single image it collects a sequence of frames, corrects and calibrates each one, and stitches them together.

For many applications it is a practical and far more flexible alternative to a linescan camera.

Typical uses

  • Scan a long object - grab a sequence of images while the object moves past the camera and get one long image back

    • with or without overlap between the images

    • from one camera or from several

  • Widen the field of view - stitch several cameras side by side into one wide image

    • each camera with its own shading correction

    • each camera resampled to remove lens and perspective distortion

  • Follow a moving object - change the resampled area for every trigger

  • Keep several cameras in step - deliver only images that arrived together, and drop the ones that did not

  • Scan in colour - full colour stitching in real time

Each camera is grabbed, corrected and resampled in its own thread, so adding cameras costs far less time than doing the same work in the Scorpion toolbox.

When the cameras are 3D calibrated, the 2DScanner is in effect a 3D scanning device - and 3D calibration is what makes stitching several cameras line up properly.

The driver ships with the Scorpion Vision Installer and is installed in the Scorpion Runtime folder. It requires Scorpion Vision Software version XII or later.

2DScanning from a single camera

Note

The 2DScanner also runs on SMARTedge (Linux ARM64). The same 2DScanner.ini works on both platforms - Windows .dll names for the camera driver, filter and resampler are translated to their Linux .so equivalents automatically.

Note

Release notes list the driver version each feature arrived in, and link to the download for that version.
