Configure Basic Counting Functions

To ensure proper device operation, the basic counting functions must be configured first, which include configuring deployment parameters, line crossing counting, region monitoring, etc. This section describes how to configure them.

Limitations: Uncontrollable Factors Affecting Accuracy

The following target-related factors may affect people counting accuracy. They are uncontrollable factors, which cannot be predicted or prevented in advance.

• Target appearance and characteristics:
  • Low color contrast: Recognition challenges when targets and the floor have similar colors.
  • Shape similarity: Non-human objects with a human-like silhouette may trigger false detections.
  • Short target miss: When installed at a height of 3.3 to 3.5 meters, the device is more likely to miss shorter targets (such as children).
• Target motion and density:
  • High velocity: Tracking may be inaccurate for individuals walking faster than 2.5 m/s.
  • Dense crowding: Accuracy decreases when the distance between targets is less than 30 cm.
• Specific scenarios:
  • Partial occlusion: The risk of missed detection increases with the proportion of the target obscured by other objects.
  • Simultaneous bidirectional crossing: When two people pass through the detection line simultaneously in opposite directions and in close proximity, it may result in a missed count for both individuals.
  • ID inheritance at the FOV edge: At the FOV edge, the simultaneous disappearance of one target and appearance of another may cause a tracking identity inheritance.
