Trying to make custom WKT for a non-Earth projection to spatially reference images taken with microscope
I'm working with non spatially-referenced images produced from a laser ablation system. Along with the image, the software produces an "align" file of the same name - an xml file that contains the XY center point of each image (coordinates are in microns) and the XY size (in microns) along with any rotation.
I would like to display the images (we typically generate about 1000 images / day) in their correct relative positions and sizes.
The laser has a stage with a cartesian positive XY coordinate system (in microns), and the origin in the SW corner.
Are there any resources for defining a custom CRS in WKT or has anyone done something like this before? I know the units are in microns, the center point of my CRS, and the height and width of the coordinate reference system (and that it is planar). Any help is much appreciated, my progress so far is located here: https://github.com/rbavery/custom_spatial_reference/blob/master/spatial_ref_imgs.ipynb
