Embodiment 1
[0027] figure 1 This is a flowchart of the navigation guide point mining method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where navigation guide points need to be mined, for example, in general navigation scenarios such as driving navigation and walking navigation. The method can be performed by a navigation guidance point excavation device, which can be implemented in software and / or hardware, and can be integrated on equipment, such as vehicle-mounted terminal equipment.
[0028] like figure 1 As shown, the navigation guidance point mining method specifically includes:
[0029] S101. Select candidate points of the target POI from the road network.
[0030] In the embodiment of the present invention, the candidate points of the target POI can be selected by analyzing the road network data of the target POI (Point of Interest, point of interest). Exemplarily, based on road network data analysis, first determine the type o...
Embodiment 2
[0041] figure 2 This is a flowchart of the method for mining navigation guidance points provided in Embodiment 2 of the present invention. On the basis of Embodiment 1, this Embodiment 2 further optimizes the operations of determining trajectory features and road network features. like figure 2 As shown, the method includes:
[0042] S201. Select candidate points of the target POI from the road network.
[0043] S202. Draw the historical trajectory data of the target POI on a target trajectory graph centered on the target POI.
[0044] Wherein, the size of the target trajectory map is a first value (unit is meters), exemplarily, the first value is 800×800 (the size of the target trajectory map is 800×800 square meters). It should be noted that each size value in this embodiment may be positively correlated with the size of the target POI, that is, if the size of the target POI is larger, the size value is larger; if the size of the target POI is smaller, the size value s...
Embodiment 3
[0061] image 3 This is a flow chart of the navigation guide point mining method provided by the third embodiment of the present invention. On the basis of the above embodiment, this embodiment adds the distance feature between the candidate point and the target POI when determining the guide point.
[0062] like image 3 As shown, the method includes:
[0063] S301. Select candidate points of the target POI from the road network.
[0064] S302. Determine the trajectory feature of the candidate point according to the historical trajectory data of the target POI.
[0065] S303. Determine the road network feature of the candidate point and the road network feature of the target POI.
[0066] S304. Determine the distance feature of the candidate point according to the position of the candidate point and the position of the target POI.
[0067] Among them, the distance between the candidate point and the target POI is also a judgment condition for determining whether the candi...
