◆ tracking_id
optional Identifier osi3::DetectedItemHeader::tracking_id = 1 |
Specific ID of the detected item as assigned by the sensor internally.
Needs not to match with ground_truth_id
.
◆ ground_truth_id
repeated Identifier osi3::DetectedItemHeader::ground_truth_id = 2 |
The ID of the original detected item in the ground truth.
◆ existence_probability
optional double osi3::DetectedItemHeader::existence_probability = 3 |
The estimated probability that this detected item really exists, not based on history.
- Note
- Use as confidence measure where a low value means less confidence and a high value indicates strong confidence.
- Rules
- is_greater_than_or_equal_to: 0is_less_than_or_equal_to: 1
◆ age
optional double osi3::DetectedItemHeader::age = 4 |
The amount of time that this detected object has been continuously observed/tracked.
- Note
- \( Timestamp - Age := \) 'point in time' when the object has been observed for the first time.
Unit: s
◆ measurement_state
optional MeasurementState osi3::DetectedItemHeader::measurement_state = 5 |
The measurement state.
◆ sensor_id
repeated Identifier osi3::DetectedItemHeader::sensor_id = 6 |
A list of physical sensors which detected this detected item.
If SensorData
has detected entities and all detections are missing, then e.g. the number of sensors can confirm the existence_probability
.
- Note
- This information can be determined via the detected entities' detections (
...Detection::object_id = 'this detected item' ) and the sensors (their IDs) to which these detections belong.
