Fishbone.Plugins.Halcon24111

Calls MVTec HALCON 24.11 from Fishbone scripts. It needs HALCON installed.

  • HalconOperatorPlugin registers every HALCON operator under its HDevelop name, like read_image or affine_trans_point_2d.
  • HalconProcedurePlugin registers the HDevelop procedures (.hdvp) in one or more folders. Registering again doesn't re-read them, so call HalconProcedurePlugin.Reload(folders) after the files change.
  • Both show images, regions and XLD contours in the debugger.

A call reads like in HDevelop, in the same order, with out on the outputs:

read_image(out image, "fabrik");
threshold(image, out region, 128, 255);
count_obj(region, out n);

Tuples

A control output is a HALCON tuple, and it comes back as an ordinary script value. What you get depends on how many elements it has:

Elements Script value
none null
one the value itself: a long, a double or a string. A handle, like a dictionary, stays an HTuple
two or more a list of them, with each handle a one-element HTuple

So the same line gives a different kind of value depending on the image. With one region, area_center(regions, out areas, out rows, out cols) makes areas a number, and foreach (a in areas) fails, since a number isn't something to loop over. With none, areas is null.

This is deliberate. The plugin doesn't guess, and a script handles it the way HDevelop or C# code does: take the count from the objects, and pick each element with tuple_select. That works for none, one or many:

area_center(regions, out areas, out rows, out cols);
count_obj(regions, out n);
for (i in 0, n) {
    tuple_select(areas, i, out area);
    println(area);
}

Going the other way, a script list becomes a tuple, and [] is the empty tuple.
