Abstract: Examples disclosed herein involve a computing system configured to (i) receive sensor data associated with a vehicle's period of operation in an environment including (a) trajectory data associated with the vehicle and (b) at least one of trajectory data associated with one or more agents in the environment or data associated with one or more static objects in the environment, (ii) determine that at least one of (a) the one or more agents or (b) the one or more static objects is relevant to the vehicle, (iii) identify one or more times when there is a change to the one or more agents or the one or more static objects relevant to the vehicle, (iv) designate each identified time as a boundary point that separates the period of operation into one or more scenes, and (v) generate a representation of the one or more scenes based on the designated boundary points.

Abstract: Examples disclosed herein involve a computing system configured to (i) obtain (a) a first set of sensor data captured by a first sensor system of a first vehicle that indicates the first vehicle's movement and location with a first degree of accuracy and (b) a second set of sensor data captured by a second sensor system of a second vehicle that indicates the second vehicle's movement and location with a second degree of accuracy that differs from the first degree of accuracy, (ii) based on the first set of sensor data, derive a first trajectory for the first vehicle that is defined in terms of a source-agnostic coordinate frame, (iii) based on the second set of sensor data, derive a second trajectory for the second vehicle that is defined in terms of the source-agnostic coordinate frame, and (iv) store the first and second trajectories in a database of source-agnostic trajectories.
