Edge Precision improves the calculation of the tag boundaries.
On
- Provides more stable corner detection
- Improves bounding-box and pose calculations
- Helps under challenging lighting or viewing angles
- Slightly increases processing time
Off
- Reduces image-processing load
- Provides faster detection
- May reduce stability around unclear tag boundaries
Keep Edge Precision on when accurate position, distance, or orientation information is required.
Turn it off when speed is the main priority, and the tags are clear and close to the camera.
