Description
Sample visualization and alignment for ESS experimental setups requires
knowledge of the pixel size of the imaged sample. Two cameras placed at 90
degrees to each other are used to obtain three dimensional position information
of the sample and sample features. A calibration target with features of known
dimensions is placed at the sample position and images captured on the two
cameras. Using image processing routines from the OpenCV library in an
areaDetector plugin, the features are identified in the image, the image
corrected for any rotation of the calibration target, and the pixel location of
the feature corners calculated.
