Data:
- uint32_t time_offset
- Offset from the timestamp in sensor_buffer_t to apply for this object.
- uint32_t distance
- Distance to the object from the sensor, in millimeters (mm).
- int32_t speed
- Speed of the object, in millimeters per second (mm/s).
- uint16_t track_id
- Track identifier associated with this object.
- int16_t azimuth
- Azimuth angle, in hundredth of degrees with a -/+18000 range, centered on the forward axis of the sensor.
A positive angle indicates clockwise direction.
- uint32_t flags
- Bitfield with values based on the sensor_radar_track_flags_t enumeration.
- int32_t acceleration
- Acceleration of the object, in millimeters per second squared (mm/s2).
- uint16_t width
- Width of the object, in millimeters (mm).
- int16_t lateral_speed
- Lateral speed, in millimeters per second (mm/s).
- uint8_t validity_level
- Validity level of the target, represented as a percentage value, with 100 being the highest validity.
A higher validity level indicates more confidence in the measurement.
- uint8_t reserved[3]
- For internal use only; do not use.
Library:
libsensor
Description:
The data payload in the sensor_buffer_t data field is an array of these structures.
