Set Confidence Threshold

This block sets the minimum confidence required for an AprilTag detection to be accepted.

For example:

0.5

A higher threshold generally requires a more reliable detection, while a lower threshold may allow detections under less ideal conditions.

Use a higher threshold when:

• You want more reliable detections.
• False detections need to be reduced.

Use a lower threshold when:

• The tag is difficult to detect.
• Lighting or camera conditions are less favourable.
