Abstract

Processing video and sensor data associated with a vehicle Apparatus (5) is configured to: obtain first data corresponding to video data from a video camera (6) associated with a vehicle; obtain second data corresponding to sensor data from one or more sensors (8) associated with the vehicle; form a data structure including metadata and the first and second data, wherein first timing information for the first data is included in the metadata and second timing information for the second data is included in the second data, wherein the first and second timing information enable the first and second data to be temporally related.

2. The method according to claim 1, wherein the vehicle or the vehicle and the other vehicle are at equivalent positions when positioned on substantially a same line, preferably wherein the line is substantially perpendicular to a direction of movement of the vehicle with which the second data are associated, at one or more times before the particular time.

3. The method according to claim 1, wherein determining equivalent positions comprises extrapolating or interpolating based on one or more recorded positions of the vehicle with which the first data are associated.

4. The method according to claim 1, wherein determining equivalent positions comprises using information about the distances travelled by the vehicle or by the vehicle and the other vehicle since previous equivalent positions.

5. The method according to claim 1, comprising:

parameterising a path taken by the vehicle with which the second data are associated; and

parameterising a path taken by the vehicle with which the first data are associated such that, when the vehicle, the other vehicle, or both the vehicle and the other vehicle are at equivalent positions, the parameters used to parameterise the paths taken by the vehicle, the other vehicle, or both the vehicle and the other vehicle are substantially equal.

6. The method according to claim 5, wherein parameterising the path taken by the vehicle with which the second data are associated comprises determining a distance travelled by the vehicle with which the second data are associated as a function of time.

7. The method according to claim 6, wherein parameterizing the path taken by the vehicle with which the first data are associated comprises, for each of a set of distances travelled by the vehicle with which the second data are associated:

determining a time at which the vehicle with which the first data are associated is at an equivalent position to the vehicle with which the second data are associated; and

associating the distance travelled by the vehicle with which the second data are associated with the determined time.

8. The method according to claim 5, wherein controlling display of the first data comprises:

determining a parameter of the path taken by the vehicle associated with the second data at a particular time;

determining a time at which the parameter of the path taken by the vehicle associated with the first data is substantially equal to the determined parameter; and

displaying first data corresponding to the determined time.

9. The method according to claim 5, wherein controlling display of the second data comprises:

determining a parameter of the path taken by the vehicle associated with the first data at a particular time;

determining a time at which the parameter of the path taken by the vehicle associated with the second data is substantially equal to the determined parameter; and

displaying second data corresponding to the determined time.

10. The method according to claim 1, wherein display of the first or second data is controlled in dependence upon a user input selecting the first or second data.

11. A non-transitory computer-readable storage medium storing a computer program for performing a method comprising:

obtaining first data associated with a vehicle, the first data comprising positioning data indicative of positioning of the vehicle and video data from a camera associated with the vehicle and indicative of a point of view from the vehicle;

obtaining second data associated with the vehicle or with another vehicle, the second data comprising positioning data indicative of the positioning of the vehicle or positioning of the other vehicle and video data from the camera associated with the vehicle indicative of the point of view from the vehicle or from a camera associated with the other vehicle indicative of a point of view from the other vehicle;

determining alignment data for the second data, the alignment data comprising an array of map distances and respective timing information, the map distance corresponding a distance travelled from a defined start point;

determining alignment data for the first data such that when the first and second vehicle are at equivalent positions the map distances for the first and second vehicles are the same; and

causing at least some of the video that is displayed at a particular time relates to equivalent positions of video data comprised in the first data and at least some of the video data comprised in the second data to be displayed, an effective playback rate of data from the second data being controlled using a clock and an effective playback rate of data from the first data is varied using the alignment data such that the video data from the first data and the video data from the second data are displayed simultaneously and are associated, respectively, with different points in time.
