======================================================================

CONTEXT:
I am building a photogrammetry pre-processing utility for archaeologists and palaeontologists. I need research:

RESEARCH PROMPT 2:

**Coded photogrammetry targets**: What types of coded targets are used in archaeological photogrammetry? Cover: Agisoft Metashape circular coded targets, ArUco markers, ChArUco boards, and April Tags. For each: what is the detection algorithm, what OpenCV module handles it, and what output format does Metashape/ODM expect for target positions?
