Methods, devices, and systems for processing sensor data of vehicles

A method, comprising:

• receiving sensor data sensed by a plurality of sensors sensing an environment of a vehicle, the sensor data being sensed over a desired duration;
• accessing a first timestamp, a second timestamp, and a third timestamp of a sensor signal from a selected sensor of the plurality of sensors, wherein the first, second, and third timestamps occur sequentially within the desired duration;
• calculating a first midpoint between the first timestamp and the second timestamp;
• calculating a second midpoint between the second timestamp and the third timestamp;
• creating a first data bucket based on the first and second midpoints by associating the first data bucket with a first period of time that corresponds to a time between the first midpoint and the second midpoint;
• and
• generating a data structure using the first data bucket by:
• placing sensor data of the selected sensor sensed during the first period of time in the first data bucket;
• checking timestamps of other sensor signals from other sensors of the plurality of sensors;
• and
• placing all sensor data of the other sensors sensed during the first period of time in the first data bucket when the timestamps of the other sensor signals from other sensors fall within the first period of time,
• wherein, when the timestamps of the other sensor signals from other sensors overlap with a start time of the first period of time, sensor data associated with the timestamps of the other sensor signals from other sensors that overlapped with the start time are placed in the first data bucket, and
• wherein, when the timestamps of the other sensor signals from other sensors overlap with an end time of the first period of time, sensor data associated with the timestamps of the other sensor signals from other sensors that overlapped with the end time are placed in a second data bucket associated with a second period of time.

A system, comprising:

• a first device that:
• receives sensor signals indicative of sensor data sensed by a plurality of sensors of a vehicle;
• records, within a desired duration, a first timestamp, a second timestamp, and a third timestamp for a sensor signal of a selected sensor of the plurality of sensors;
• and
• stores the sensor data sensed by the plurality of sensors of the vehicle and the first, second, and third timestamps to a first storage system according to a first data structure;
• and
• at least one second device that:
• receives the sensor data sensed by the plurality of sensors of the vehicle from the first storage system;
• accesses the first timestamp, the second timestamp, and the third timestamp of the sensor signal of the selected sensor;
• calculates a first midpoint between the first timestamp and the second timestamp;
• calculates a second midpoint between the second timestamp and the third timestamp;
• creates a first data bucket based on the first and second midpoints by associating the first data bucket with a first period of time that corresponds to a time between the first midpoint and the second midpoint;
• generates a second data structure for the sensor data sensed by the plurality of sensors of the vehicle using the first data bucket by:
• placing sensor data of the selected sensor sensed during the first period of time in the first data bucket;
• checking timestamps of other sensor signals from other sensors of the plurality of sensors;
• and
• placing all sensor data of the other sensors sensed during the first period of time in the first data bucket when the timestamps of the other sensor signals from other sensors fall within the first period of time;
• and
• stores the second data structure in a second storage system,
• wherein, when the timestamps of the other sensor signals from other sensors overlap with a start time of the first period of time, sensor data associated with the timestamps of the other sensor signals from other sensors that overlapped with the start time are placed in the first data bucket, and
• wherein, when the timestamps of the other sensor signals from other sensors overlap with an end time of the first period of time, sensor data associated with the timestamps of the other sensor signals from other sensors that overlapped with the end time are placed in a second data bucket associated with a second period of time.
