Problems solved by technology

[0003] At present, there are two main methods of obtaining travel information: 1) Surveying the travel time and location of different groups of people through questionnaires. The main problem of this method is that the number of samples is limited, the execution efficiency is low, and it does not have time continuity; 2) Construct a traffic model to calculate travel information based on the data generated by sensors deployed on vehicles or streets. The main problem with this method is that the model is too complex, and the effect of output data is usually not ideal

Embodiment 1

[0030] Figure 1A It is a flowchart of an information mining method provided by Embodiment 1 of the present invention. This embodiment is applicable to how to accurately and efficiently mine information, and is especially suitable for mining travel information. The method can be executed by the information mining device provided by the embodiment of the present invention, and the device can be realized by software and / or hardware. see Figure 1A , the method specifically includes:

[0031] S110. Determine at least two trajectory segments according to the location of the trajectory point and the passing time of the trajectory point.

[0032] Among them, the trajectory refers to the use of positioning point data collected by smart devices (such as mobile phones, smart watches, etc.) or applications with positioning functions based on the mobile Internet during a trip with a purpose, according to the order of collection time. obtained after sorting. The track point is the posi...

Embodiment 2

[0043] Figure 2A It is a flow chart of an information mining method provided by Embodiment 2 of the present invention. On the basis of Embodiment 1 above, this embodiment further explains the determination of at least two trajectory segments according to the position of the trajectory point and the passing time of the trajectory point illustrate. see Figure 2A , the method specifically includes:

[0044] S210. Determine the motion state of each track segment according to the position of the track point in the track segment and the passing time of the track point.

[0045] Wherein, the motion state of the trajectory segment can be static or motion.

[0046] Specifically, the spatial distance between two trajectory points can be determined according to the position of the trajectory point in the trajectory segment; the time difference between the two trajectory points can be determined according to the passing time of the trajectory point in the trajectory segment; Determi...

Embodiment 3

[0062] image 3 It is a flow chart of an information mining method provided by Embodiment 3 of the present invention. On the basis of the above embodiments, this embodiment further explains the determination of travel information based on the travel trajectory segment. see image 3 , the method specifically includes:

[0063] S310. Determine at least two trajectory segments according to the location of the trajectory point and the passing time of the trajectory point.

[0064] S320, if the at least two trajectory segments include a first stationary trajectory segment, a moving trajectory segment, and a second stationary trajectory segment that are sequentially adjacent, and the duration of the first static trajectory segment and the second static trajectory segment is greater than a second time threshold, If the distance is smaller than the second distance threshold, the duration of the motion trajectory segment is greater than the third time threshold, and the distance is g...

Abstract

The embodiment of the invention discloses an information mining method and device, a server and a storage medium, wherein the method is characterized in that at least two trajectory segment are determined according to that position of the trajectory points and the path time of the trajectory points; if it is determined that at least two trajectory segments include travel trajectory segments according to the time length and distance of each trajectory segment, the travel information is determined according to the travel trajectory segment. The technical proposal provided by the embodiment of the invention is processed based on the position of the track point and the transit time of the track point, so that the travel information can be obtained quickly, continuously and reliably.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and in particular, to an information mining method, device, server, and storage medium. Background technique [0002] OD (Origin-Destination, travel origin-destination), that is, travel information, is an important data that describes the distribution of crowd travel behavior in time, space, frequency and other dimensions, and has very important guiding significance for urban planning and urban management. [0003] At present, there are two main methods of obtaining travel information: 1) Surveying the travel time and location of different groups of people through questionnaires. The main problem of this method is that the number of samples is limited, the execution efficiency is low, and it does not have time continuity; 2) Based on the data generated by sensors deployed on vehicles or streets, construct a traffic model to calculate travel information. Th...
