    Abstract: Embodiments provide a hardware-based mechanism to continuously calibrate a set of sensors on a vehicle while the vehicle is in motion or in use. Specifically, each sensor is mounted on a respective rigid mounting device placed on the vehicle. A secondary sensing device for calibration is also rigidly mounted on the mounting device such that the relative position between the secondary device and the camera sensor can remain unchanged. The secondary sensing devices can then be used to detect a relative distance and/or position of the same calibration target. The sensed data is then used to determine, via stereo triangulation, the relative positions of the two secondary sensing devices, which in turn indicates the relative positions of the sensors.

    Abstract: Examples disclosed herein may involve a computing system that is operable to (i) identify a set of vehicle trajectories that are associated with a segment of a road network, (ii) identify a first cluster of sampling points between the identified set of vehicle trajectories and a first sampling position along the segment, wherein the first cluster has an associated geospatial position and is inferred to be associated with one given lane of the segment, (iii) identify a subset of vehicle trajectories in the identified set that are inferred to be associated with the given lane between the first sampling position and a second sampling position along the segment, (iv) identify a second cluster of sampling points between the identified subset of vehicle trajectories and the second sampling position, wherein the second cluster has an associated geospatial position, and (v) determine a geospatial geometry of the given lane.

    Abstract: Examples disclosed herein may involve a computing system that is operable to (i) generate first structure data from one or more first image data, wherein the first structure data comprises one or more visible features captured in the one or more first image data, (ii) generate further structure data from one or more further image data, wherein the further structure data comprises one or more visible features captured in the one or more further image data, (iii) determine pose constraints for the further structure data based on common visible features, (iv) determine a transformation of the further structure data relative to the first structure data using the determined pose constraints, and (v) generate combined structure data using the determined transformation to fuse the further structure data and the first structure data.

    Abstract: Examples disclosed herein may involve a computing system that is operable to (i) receive first data of one or more geographical environments from a first type of localization sensor, (ii) receive second data of the one or more geographical environments from a second type of localization sensor, (iii) determine constraints from the first data and the second data, (iv) determine shared pose data associated with both of the first data and the second data using the constraints determined from both the first data and the second data by determining one or more sequences of common poses between respective poses generated from each of the first and second data, wherein the shared pose data provides a common coordinate frame for the first data and the second data, and (v) generate a map of the one or more geographical environments using the determined shared pose data.
