Data Source

The configuration storing the sources to retrieve the point cloud data for further processing.

Table 1. Available fields in blickfeld.percept_pipeline.config.DataSource
Field	Type	Default	Unit
qb2_setup	Qb2Setup	-	-
qb2_setup	Use Qb2 lidars to retrieve point clouds
geolocation_of_map	optional base.config.Geolocation	-	-
geolocation_of_map	Geolocation of data source. This references the map coordinate system of this data source to the world. Individual lidars are referenced to the map coordinate system via their `map_from_lidar` transform. [NOTE] If the map_from_lidar transform is not an identity transformation, this is not the geolocation of an individual sensor.

Qb2

Configuration for retrieving point clouds from a Qb2

Table 2. Available fields in blickfeld.percept_pipeline.config.DataSource.Qb2
Field	Type	Default	Unit
fqdn	string	-	-
fqdn	The fully qualified domain name of the Qb2 device. For on-device processing/configuration, 'fqdn' can be set to an empty string to request the data of the current device.
map_from_lidar	base.geometry.Transform	-	-
map_from_lidar	Transformation from the lidar frame to the map frame. If this transform is not set, this will be interpreted as identify transformation. Transforming all point cloud topics into the map frame results in a globally consistent combined point cloud in map frame.
application_key	optional string	-	-
application_key	Application key with authorized access level. Required if user-management is enabled on externally connected devices.
serial_number	optional string	-	-
serial_number	Serial number. Required if user-management is enabled on externally connected devices.
metadata	optional google.protobuf.Struct	-	-
metadata	Arbitrary metadata storage for client applications

Trigger

Configuration of Trigger Mode. In trigger mode the processing pipeline will reduce the frequency at which point clouds and state lists are getting computed to reduce the amount of data transmitted between the processing device and configured 'lidars'.

Table 3. Available fields in blickfeld.percept_pipeline.config.DataSource.Trigger
Field	Type	Default	Unit
frequency	float	-	Hz
frequency	The frequency at which data is getting requested from the lidars and outputs are generated.

Qb2 Setup

The configuration of a Qb2 setup of the LiDAR devices

Table 4. Available fields in blickfeld.percept_pipeline.config.DataSource.Qb2Setup
Field	Type	Default	Unit
lidars	repeated Qb2	-	-
lidars	the qb2 lidars to get the point clouds from
trigger	optional Trigger	-	-
trigger	If the field is set trigger mode is enabled. If the field is not set, the pipeline outputs are computed with the frequency of configured lidars, i.e. the scan pattern configured on those.
