An update has been performed to software designed to do very rapid automated measurements of craters created in sandy substrates by rocket exhaust on liftoff. The previous software was optimized for pristine lab geometry and lighting conditions. This software has been enhanced to include a section for manual measurements of crater parameters; namely, crater depth, crater full width at half max, and estimated crater volume. The tools provide a very rapid method to measure these manual parameters to ease the burden of analyzing large data sets.
This software allows for rapid quantization
of the rocket crater parameters where
automated methods may not work. The
progress of spreadsheet data is continuously
saved so that data is never lost, and data can
be copied to clipboards and pasted to other
software for analysis. The volume estimation
of a crater is based on the central max depth
axis line, and the polygonal shape of the
crater is integrated around that axis.
