"""Run one HDevelop external procedure (.hdvp) via HDevEngine and print outputs.
|
||
|
|
|
||
|
|
This is the generic form of the tested run_compare.py driver. Pass input control
|
||
|
|
params with --set, name the outputs to read with --get; results print as a JSON
|
||
|
|
object on stdout.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
/mnt/c/Users/NAURA/.local/bin/uv.exe run python \
|
||
|
|
.claude/skills/halcon/scripts/run_procedure.py \
|
||
|
|
--proc-path C:/workspace/agent-studio/halcon-001 \
|
||
|
|
--proc find_circles \
|
||
|
|
--set ImageFile=C:/data/a.png \
|
||
|
|
--set RoiFile=C:/workspace/agent-studio/halcon-001/roi.hobj \
|
||
|
|
--get FitRow --get FitCol --get MetroRow --get MetroCol
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
- Always use ABSOLUTE paths for images/ROIs (HDevEngine has no cwd notion).
|
||
|
|
- Numeric --set values are auto-typed; use commas for a tuple (e.g. --set T=10,20).
|
||
|
|
- Wrap in a loop from your own Python for batch processing.
