Definitions
- the invention relates to a method for updating a digital map.
- the invention relates to a device, a computer program and a machine-readable storage medium.
- the published application DE 10 2012 212 740 A1 discloses a system and a method for updating a digital map of a driver assistance system.
- the published application DE 10 2015222 962 A1 discloses a method for aggregating lane information for digital map services.
- the published application DE 10 2017222 496 A1 discloses a method for updating a digital navigation map.
- the object on which the invention is based is to be seen as providing a concept for efficiently updating a digital map.
- a method for updating a digital map comprising the following steps: receiving motor vehicle data signals which represent respective motor vehicle data from a number of motor vehicles, parallel updating of a number of spatially separate map segments of the digital map based on the motor vehicle data in order to update the digital map.
- a device which is set up to carry out all the steps of the method according to the first aspect.
- a computer program which comprises instructions which, when the computer program is executed by a computer, for example by the device according to the second aspect, cause it to carry out a method according to the first aspect.
- a machine-readable storage medium on which the computer program according to the third aspect is stored.
- the invention is based on and includes the knowledge that the above object can be achieved in that a number of spatially separate map segments are updated in parallel.
- parallel means simultaneously, so that the digital map can be updated faster compared to non-parallel updating, ie if the map segments were updated one after the other.
- a respective transition area immediately adjacent to a respective boundary of the several map segments and enclosing the respective map segment is defined, with the parallel updating comprising adapting the respective transition area to the respective updated map segment in such a way that the respective updated map segment is consistent with a neighborhood of the transition region.
- immediately surrounded means in the context of the description that the other map segments directly adjoin the respective updated map segment, i.e. there is no other map segment located between another map segment and the updated map segment.
- Consistent in the sense of the description means, for example, that the aligned motor vehicle trajectories required for mapping or the map itself is continuous at the transitions, i.e. in particular has no jumps and/or no kinks and/or no abrupt changes in curvature etc.
- the respective transition area is adapted to the respective updated map segment using a consistency metric.
- the fitting can be performed efficiently.
- the voltage introduced by a new trajectory can be used as a consistency metric.
- the aim of the transition area is in particular to reduce these stresses. In particular, it is only readjusted in the transition area, but in particular not in the map enclosing the transition area.
- a size and/or a shape, in particular a spatial or topological extent, of the transition area is determined based on the consistency metric. This brings about the technical advantage, for example, that the size or shape of the transition area can be determined efficiently. In particular, this brings about the technical advantage that a suitable transition area can be determined for the specifically present map segment to be updated.
- a transition area can therefore be formed, for example, as a polygon, in particular a rectangle, that completely encloses the map segment to be updated.
- a transition region may be formed as a topological extension of the graph.
- a topological extension is understood in particular to mean that all roads at the edges are or are extended by a certain distance, for example in order to be able to reach all parts within a road kilometer (in contrast to the straight line).
- a respective motor vehicle trajectory of the motor vehicles is determined based on the motor vehicle data, with the respective determined motor vehicle trajectories being aligned on the digital map, with the alignment of the respective determined motor vehicle trajectories and the parallel updating of a plurality of spatially separate map segments in overlapping geographic regions of the digital map are executed one after the other, so that the alignment of the respective determined motor vehicle trajectories is omitted during the parallel updating of several spatially separated map segments.
- the parallel updating includes creating a new map segment and/or updating the newly created map segment. This brings about the technical advantage, for example, that the map segment can be efficiently recreated or that a newly created map segment can be efficiently updated.
- motor vehicle data in the sense of the description includes, for example, one or more of the following data: environment data, speed data, position data, sensor data, in particular environment sensor data from an environment sensor of the motor vehicle representing the environment of the motor vehicle, environment data representing the environment of the motor vehicle, in particular a digital model of the environment.
- An environment sensor is, for example, one of the following environment sensors: radar sensor, lidar sensor, video sensor, infrared sensor, magnetic field sensor and ultrasonic sensor.
- the method of the first aspect is a computer-implemented method.
- 1 shows a flowchart of a method for updating a digital map, 2 a device,
- Figure 4 shows a digital map
- FIG. 1 shows a flow chart of a method for updating a digital map, comprising the following steps:
- the 2 shows a device 201.
- the device 201 is set up to carry out all the steps of the method according to the first aspect.
- FIG. 3 shows a machine-readable storage medium 301.
- a computer program 303 is stored on the machine-readable storage medium 301.
- FIG. The computer program 303 includes instructions which, when the computer program 303 is executed, for example by the device 201 of FIG. 2, cause it to execute a method according to the first aspect.
- Fig. 4 shows a digital map 401.
- the digital map 401 comprises a first map segment 403.
- a box or a frame 405 completely enclosing the first map segment 403 is defined or fixed or placed around the first map segment 403.
- a transition area 406 is thus fixed or defined between the first map segment 403 and the box 405, which is shown hatched.
- the digital map 401 includes a first street 407, a second street 409 and a third street 411.
- the first street 407 and the third street 411 run partially in the first map segment 403.
- the second street 409 runs outside the first map segment 403, but partly inside the transition area 406.
- a motor vehicle trajectory 413 that runs within first map segment 403 is also drawn in.
- a second map segment 415 of the digital map is also shown.
- the two map segments 403, 415 are spatially separated from one another.
- the two map segments 403, 415 are updated in parallel.
- the parallel updating includes adapting the transition area 406 to the updated first map segment 403 in such a way that the updated first map segment 403 is consistent with an environment of the second map segment 415 .
- the consistency with the environment means in particular that it is consistent at the frame 405 or the previously undefined frame around the transition area 406 around the map segment 415 .
- the motor vehicle trajectory 413 is aligned with a lane (not shown) of the third street 411 .
- map segments are not predefined, but are redefined each time new data is processed.
