Embodiment 1

[0034] figure 2 It is a flow chart of a road section description method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of accurately describing the road section to be described. Typically, this embodiment is applicable to a situation in which a road segment that needs to be reminded of the user is accurately described in a map application, so that the user can accurately locate the road segment. The method can be executed by a road segment description device, and the device can be realized by software and / or hardware. see figure 2 , the road section description method provided in this embodiment includes:

[0035] S110. Determine a target sub-segment from the sub-segments included in the road segment to be described.

[0036] Wherein, the road section to be described is a road section that needs to be described, and the road section includes at least one sub-road section.

[0037] A sub-section is the smallest basic uni...

Embodiment 2

[0069] image 3 It is a flow chart of a road section description method provided in Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see image 3 , the road section description method provided in this embodiment includes:

[0070] S210. Determine a target sub-segment from the sub-segments included in the road segment to be described.

[0071] S220. Determine a target semantic element according to the proximity relationship information of the target sub-road section.

[0072] S230. Based on at least one semantic template, generate at least one candidate description text according to the target semantic element.

[0073] Wherein, the semantic template refers to a template for generating target description text.

[0074] For example, the semantic template may be: from the semantic element of the start subsection of the road section to be described to the semantic element of the end subsection o...

Embodiment 3

[0088] Figure 4a It is a flow chart of a road section description method provided by Embodiment 3 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see Figure 4a , the road section description method provided in this embodiment includes:

[0089] S310. By analyzing the connectivity and characteristics of the road network, mining semantic elements related to roads to establish a road knowledge base.

[0090] For the display effect of specific road-related semantic elements, see Figure 4b .

[0091] Wherein, the semantic elements include two types, one is the basic information of the Link (subsection), such as the road name and position coordinates, etc.; the other is the proximity relationship information of the Link, such as the nearest bridge from the Link, Link's nearest intersection, the nearest toll station to the Link, etc.

[0092] see Figure 4c , adding the adjacent relationship information o...

Abstract

The embodiment of the invention discloses a road section description method and device, equipment and a medium, and relates to the field of electronic maps. The method comprises the following steps: determining a target sub-road section from sub-road sections included in a to-be-described road section; determining a target semantic element according to the proximity relation information of the target sub-road section; and generating a target description text of the road section to be described according to the target semantic elements. The embodiment of the invention provides a road section description method and device, equipment and a medium. Accurate description of a to-be-described road section is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic maps, and in particular, relate to a method, device, device and medium for road section description. Background technique [0002] see figure 1 , in a map-based application, it is necessary to describe a designated road 100 through a text prompt, so as to inform the user to avoid, be vigilant or pay attention to this road section. [0003] The current description method for the road segment to be described is: use the name of the road to which the road segment belongs to describe. [0004] However, the above method has the following problems: [0005] The road section to be described may only be a part of a road, and using the road name directly will cause a large deviation in user understanding. Contents of the invention [0006] Embodiments of the present invention provide a road segment description method, device, equipment and medium, so as to realize accurate description o...
