![]() Based on the size and position of the central black dot, he 'L'-shaped axes pair - to be found by Engauge at a later point - is painted at a customised position, at the right size, for each individual target picture.īy the way, does command the script language (as read by the option -filecmdscript) offer any "power user" batch processing options which could be useful for a project like mine? This is taken care of by the initial image processing step. Consequently my scanning system has to deal with the targets appearing at slightly different positions and sizes in every picture. My problem is that I am too much of a cheapskate to buy a scanner, and too lazy to build some kind of rig for holding the camera at a well defined position in relation to the targets. I had to add a postprocessing step in my script to compensate for I'm not sure I understand exactly how this template implementation would work. In case you resurrect -axis with the help of version control: I remember vaguely that things went awry when xmin or ymin were given negative values. I also tend to use Engauge now and then at work. So, in the end, I have built myself a semi-automatic target analysis system, capable of finding most of the hits on itself, but also flexible enough to allow for manual corrections, say, where holes overlap a lot. (I found no way of making engauge remember these values from invocation to invocation.) The values for the end points are then fed to engauge with the -axis flag. Before the picture is handed over to Engauge, the script paints an axis-'L' on it. In order to get around this, I've written a small Python script which detects the size and position of the central black dot of the target. The problem is that I don't have a scanner, or a solid set-up for the camera, so the targets end up in different position and sizes on the photos. From time to time I do some ISSF 10 m air pistol shooting at home, and I harness the capabilities of engauge to measure the coordinates of the hits. Let me pay back with a terse description of what I use Engauge and -axis for.
