Member Data Documentation

◆ measurement_time

optional Timestamp osi3::SensorDetectionHeader::measurement_time = 1

Time stamp at which the measurement was taken (not the time at which it was processed or at which it is transmitted) in the global synchronized time.

Note: See SensorData::timestamp and SensorData::last_measurement_time for detailed discussions on the semantics of time-related fields.

◆ cycle_counter

optional uint64 osi3::SensorDetectionHeader::cycle_counter = 2

Monotonous counter to identify the exact cycle.

In general the detection function is called periodically and cycle_counter corresponds to the number of periods.

Rules\n\code{.unparsed}: is_greater_than_or_equal_to: 0

◆ mounting_position

optional MountingPosition osi3::SensorDetectionHeader::mounting_position = 3

The physical mounting position of the sensor (origin and orientation of the sensor frame).

Both origin and orientation are given in and with respect to the host vehicle coordinate system [1].

The sensor frame's x-axis is pointing in the central viewing direction of the sensor. It is the angle bisector of the sensor's horizontal and vertical field of view. The terms horizontal and vertical must be understood as names for the two principal planes of the sensor's field of view (relative to the sensor frame's orientation), which do not have to be horizontal or vertical in the strict sense of being parallel or perpendicular to the local gravitational vector. The horizontal field of view defines the sensor frame's xy-plane and the vertical field of view defines the xz-plane. The sensor frame is right-handed and the z-axis is pointing in an upward direction.

The sensor frame uses cartesian coordinates. The sensor frame's origin is identical to sensor detection frame's origin. Detections are defined in the sensor detection frame which uses e.g. spherical coordinates.

Rules\n\code{.unparsed}: is_set

◆ mounting_position_rmse

optional MountingPosition osi3::SensorDetectionHeader::mounting_position_rmse = 4

The origin/orientation of the sensor frame represents the current mounting pose to the best knowledge of the sensor.

The estimation of the 6D pose given by the calibration. The uncertainty of this estimation is given with the corresponding 6D root mean squared error. The estimation of the current origin does not include effects due to short-time dynamics, such as pitch angles from braking, but includes long-time calibration values, such as pitch angles from luggage in the trunk.

◆ data_qualifier

optional DataQualifier osi3::SensorDetectionHeader::data_qualifier = 5

Data Qualifier expresses to what extent the content of this event can be relied on.

◆ number_of_valid_detections

optional uint32 osi3::SensorDetectionHeader::number_of_valid_detections = 6

The current number of valid detections in the detections list.

Note: This value has to be set if the list contains invalid detections.

Rules\n\code{.unparsed}: is_greater_than_or_equal_to: 0

◆ sensor_id

optional Identifier osi3::SensorDetectionHeader::sensor_id = 7

The ID of the sensor at host vehicle's mounting_position.

This ID can equal SensorData::sensor_id, if SensorData holds only data from one sensor/sensor model.

Rules\n\code{.unparsed}: is_set

◆ extended_qualifier

optional ExtendedQualifier osi3::SensorDetectionHeader::extended_qualifier = 8
