[0002] A system for rapidly generating road information of a reconstructed high-precision map is known. The system draws lane dividers based on the vehicle motion trajectories of two adjacent lanes. If no vehicle trajectory is generated between the two lane dividers and the distance between the lane dividers is greater than or less than the standard width of the road, it is recognized that the area between the lane dividers is not a lane but a central isolation strip (for example, refer to Chinese invention patent CN111578964B).

[0061] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0062] Figure 1 FIG. 1 is a flow chart of a method for identifying an isolation zone according to a first embodiment of the present invention. Figure 1 As shown, the isolation zone identification method for identifying the isolation zone may include:

[0063] Step S101, respectively obtaining the driving directions of the adjacent first lane and second lane.

[0064] First, the road scene data collected by the shooting vehicle is obtained, and then non-road elements in the road scene data are removed, such as vehicles, pedestrians, buildings and other non-road elements, so as to obtain lane data; then, the lane network is drawn in the three-dimensional map based on the lane data.

[0065] After the lane network is drawn, the driving directions of two adjacent vehicles are obtained respectively, such as Figure 2 As shown, the driving directions of the adjacent first lane and second lane are respectively acquired.

[0066] Step S102: determine whether the driving direction of the first lane is opposite to the driving direction of the second lane. In response to the driving direction of the first lane being opposite to the driving direction of the second lane, identify the area between the first lane and the second lane as a separation zone.

[0067] In this step, the driving direction of the first lane is compared with the driving direction of the second lane to determine whether the driving direction of the first lane is opposite to the driving direction of the second lane. If so, the area between the first lane and the second lane is identified as a separation zone.

[0068] According to the various embodiments described above, it can be seen that the embodiment of the present invention solves the technical problem in the prior art that the accuracy requirements of high-precision maps cannot be met by identifying the area between the first lane and the second lane as a separation zone in response to the driving direction of the first lane being opposite to the driving direction of the second lane. The embodiment of the present invention identifies the separation zone according to the driving direction of two adjacent lanes, which helps to improve the recognition accuracy of the separation zone, thereby meeting the accuracy requirements of the high-precision map. Moreover, since the embodiment of the present invention can automatically identify the separation zone according to the driving direction of the first lane and the driving direction of the second lane, there is no need to use manual identification, which significantly improves the recognition efficiency of the separation zone, thereby improving the efficiency of building high-precision maps.

[0069] Figure 3 FIG. 4 is a flow chart of a method for identifying an isolation zone according to a second embodiment of the present invention. Figure 3 As shown, the isolation zone identification method for identifying the isolation zone may include:

[0070] Step S301, respectively obtaining the driving directions of the adjacent first lane and second lane.

[0071] Step S302, determining whether the driving direction of the first lane is opposite to the driving direction of the second lane; if so, executing step S303; if not, executing step S306.

[0072] Step S303: obtaining a distance between the first lane and the second lane.

[0073] Step S304, determining whether the distance between the first lane and the second lane is greater than or equal to a distance threshold; if so, executing step S305; if not, executing step S307.

[0074] Step S305: identifying an area between the first lane and the second lane as a separation zone.

[0075] Step S306: manual intervention judgment.

[0076] Step S307: Identify the area between the first lane and the second lane as having no gap.

[0077] In this embodiment, if it is determined that the driving direction of the first lane is opposite to that of the second lane, it is necessary to further obtain the distance between the first lane and the second lane, and determine whether the distance between the first lane and the second lane is greater than or equal to the distance threshold; if the distance between the first lane and the second lane is greater than or equal to the distance threshold, the area between the first lane and the second lane is identified as a separation zone, otherwise, the area between the first lane and the second lane is identified as having no distance, which may be caused by a mapping error. Among them, the distance threshold can be set according to actual needs, for example, it can be set to 18cm, 20cm or 23cm, etc., and the embodiment of the present invention does not limit this.

[0078] It should be noted that if the driving direction of the first lane is not opposite to that of the second lane, manual intervention is required to ensure accurate recognition and meet the accuracy requirements of high-precision maps. If there is an irregular distance between the first lane and the second lane, manual intervention is required.

[0079] In this embodiment, when it is determined that the driving direction of the first lane is opposite to that of the second lane, the distance between the first lane and the second lane is further combined to identify whether the area between the first lane and the second lane is a separation zone, which helps to improve the recognition accuracy of the separation zone, thereby meeting the accuracy requirements of the high-precision map.

[0080] Figure 4 FIG. 4 is a flow chart of a method for identifying isolation zones according to a third embodiment of the present invention. Figure 4 As shown, the isolation zone identification method may include:

[0081] Step S401, respectively obtain the driving directions of the adjacent first lane and second lane.

[0082] Step S402, determining whether the driving direction of the first lane is opposite to the driving direction of the second lane; if so, executing step S403; if not, executing step S408.

[0083] Step S403: obtaining a distance between the first lane and the second lane.

[0084] Step S404, determining whether the distance between the first lane and the second lane is greater than or equal to a distance threshold; if so, executing step S405; if not, executing step S409.

[0085] Step S405: Identify the area between the first lane and the second lane as an unknown area, and obtain a first lane line and a second lane line of the first lane and the second lane close to the unknown area, respectively.

[0086] Step S406, determining whether the first lane line and the second lane line are both solid lines; if so, executing step 407; if not, executing step S410.

[0087] Step S407: identifying an area between the first lane and the second lane as a separation zone.

[0088] Step S408: Manual intervention judgment.

[0089] Step S409: identifying an area between the first lane and the second lane as having no gap.

[0090] Step S410: identifying an unknown area between the first lane and the second lane as an accessible area.

[0091] In this embodiment, if it is determined that the distance between the first lane and the second lane is greater than or equal to the distance threshold, the area between the first lane and the second lane is temporarily identified as an unknown area, such as Figure 5a As shown; then further obtain the first lane line and the second lane line of the first lane and the second lane near the unknown area, and determine whether the first lane line and the second lane line are both solid lines. If so, the unknown area between the first lane and the second lane is identified as a separation zone, such as Figure 5b Otherwise, the unknown area between the first lane and the second lane is identified as an accessible area, as shown in Figure 5c shown.

[0092] In order to ensure recognition accuracy, after the unknown area between the first lane and the second lane is identified as an accessible area, manual marking is required. For example, the accessible area may be further marked as a corner or a public parking area, which helps improve the accuracy of the map.

[0093] Figure 6 FIG. 4 is a flow chart of a method for identifying isolation zones according to a fourth embodiment of the present invention. Figure 6 As shown, the isolation zone identification method may include:

[0094] Step S601, respectively obtaining the driving directions of the adjacent first lane and second lane.

[0095] Step S602, determining whether the driving direction of the first lane is opposite to the driving direction of the second lane; if so, executing step S603; if not, executing step S608.

[0096] Step S603: obtaining a distance between the first lane and the second lane.

[0097] Step S604, determining whether the distance between the first lane and the second lane is greater than or equal to a distance threshold; if so, executing step S605; if not, executing step S609.

[0098] Step S605 , respectively obtaining a first lane marking and a second lane marking of the first lane and the second lane close to the unknown area.

[0099] Step S606, determining whether the first lane line and the second lane line are both solid lines; if so, executing step 607; if not, executing step S610.

[0100] Step S607: Identify the area between the first lane and the second lane as a separation zone.

[0101] Step S608: Manual intervention judgment.

[0102] Step S609: Identify the area between the first lane and the second lane as having no gap.

[0103] Step S610: identifying an unknown area between the first lane and the second lane as an accessible area.

[0104] Step S611, respectively acquiring a third lane connected to the first lane and a fourth lane connected to the second lane.

[0105] Steps S603 to S610 are repeatedly executed until all linkable lanes have been identified or it is identified that there is no gap between two adjacent lanes.

[0106] After the area between the first lane and the second lane is identified, the third lane connected to the first lane and the fourth lane connected to the second lane are obtained respectively, such as Figure 7 As shown, the area between the third lane and the fourth lane is identified. The identification process is similar to the above embodiment and will not be repeated herein.

[0107] Since the first lane is linked to the third lane, the driving direction of the first lane is usually the same as that of the third lane. Similarly, the driving direction of the second lane is also the same as that of the fourth lane. In order to improve the recognition efficiency, it is not necessary to determine whether the driving direction of the third lane is opposite to that of the fourth lane. The driving direction of the third lane and that of the fourth lane are directly determined, and the subsequent process, i.e., step S603-step S610, is continued to be executed based on the determination result. In other words, the third lane is regarded as the first lane, and the fourth lane is regarded as the second lane, and steps S603-step S610 are executed again to obtain the recognition result, which can significantly improve the recognition efficiency of the isolation zone.
