This block sets the minimum confidence required before a detection is accepted.
Only detections with confidence equal to or above the selected threshold are treated as valid.
Lower Threshold
- Detects tags under more difficult conditions
- May accept distant, unclear, or partially visible tags
- May increase false detections
Higher Threshold
- Accepts only clearer and more reliable detections
- Reduces false triggering
- May reject tags in poor lighting or at difficult angles
Practical Guidance
| Project type | Suggested approach |
| Beginner tag detection | Use a moderate threshold |
| Fast classroom demonstration | Use a moderate or lower threshold |
| Autonomous docking | Use a higher threshold |
| Poor lighting | Reduce the threshold carefully |
| Frequent false detections | Increase the threshold |
The confidence threshold filters results; it does not directly increase the processing speed.
