Embodiment 1

[0067] figure 1 It is a schematic flowchart of a method for collecting map data provided in Embodiment 1 of the present application. This embodiment is applicable to the situation where the map is updated according to the map data collected by the vehicle. This method is applied to the server and can be executed by the map data collection device configured in the server provided in the embodiment of the application. The device can use software and / or hardware implementation. Such as figure 1 As shown, the method may include:

[0068] S101. Determine a target ROI from a map, wherein the map is divided into at least two ROIs.

[0069] Wherein, the type of the map may be an administrative area map, a street map, etc., and the specific map type is determined according to business requirements, which is not limited in this embodiment. The area of ​​interest in the map is pre-divided by the technician according to the type of the map. Usually, the area of ​​interest divided by ...

Embodiment 2

[0092] figure 2 It is a schematic flowchart of a method for collecting map data provided in Embodiment 2 of the present application. This embodiment provides a specific implementation manner for the above embodiments, such as figure 2 As shown, the method may include:

[0093] S201. Determine a target ROI from a map, wherein the map is divided into at least two ROIs.

[0094] S202. Obtain the current location of the data collection terminal.

[0095] Specifically, by controlling the positioning device mounted on the data collection terminal, such as a GPS device, to send positioning information to the server, the server determines the current location of the data collection terminal according to the obtained positioning information.

[0096] S203. Send the data collection instruction to the data collection terminal currently located in the target area of ​​interest, so as to collect map data in the target area of ​​interest.

[0097] Exemplarily, assuming that the target...

Embodiment 3

[0102] image 3 It is a schematic flowchart of a method for collecting map data provided in Embodiment 3 of the present application. This embodiment provides a specific implementation manner for the above embodiments, such as image 3 As shown, the method may include:

[0103] S301. Determine a target ROI from a map, wherein the map is divided into at least two ROIs.

[0104] S302. Determine the redundancy of required map data according to the map update requirement.

[0105] Wherein, the redundancy amount of required map data represents the number of data collection terminals required to update the map.

[0106] Specifically, the area of ​​the map update area is different, and the number of data collection terminals required is also different. For example, when the map update area is large, more data collection terminals are required to participate in the collection of map data to ensure the accuracy and reliability of the updated map; for example, when the map update are...

Abstract

The invention discloses a map data acquisition method and device, electronic equipment and a medium, and relates to the field of intelligent transportation. The method concretely comprises the following steps: determining a target region of interest from a map, wherein the map is divided into at least two regions of interest; sending a data acquisition instruction for performing map data acquisition on the target region of interest to a data acquisition terminal; and receiving map data fed back by the data acquisition terminal, and updating a target region of interest in the map according to the map data. The target region of interest is determined, and the data acquisition instruction for performing map data acquisition on the target region of interest is sent to the data acquisition terminal, so that the technical effect of performing map data acquisition as required is achieved, and unnecessary redundant data collection is reduced.

Description

technical field [0001] The embodiments of the present application relate to computer technology, in particular to intelligent transportation technology, and specifically to methods, devices, electronic equipment and media for collecting map data. Background technique [0002] Maps, especially high-precision maps, need to constantly update the data in the map according to the actual environmental conditions of the geographical location. The prior art adopts a map crowdsourcing mode to collect map data. That is, collect various terminals, such as consumers' mobile terminals and vehicle-mounted terminals, collect data of the surrounding environment while the user is moving, and then upload it to the cloud server, and the cloud server will integrate the data collected by multiple terminals. to update the map. [0003] However, the problem with the existing map crowdsourcing model is that a large number of terminals may be collecting map data and sending it back to the cloud se...
