Embodiment 1

[0047] figure 1 It is a schematic flowchart of a method for monitoring the flow of people in a city provided by Embodiment 1 of the present invention. This embodiment is applicable to the monitoring of the flow of people in a city. Such as figure 1 As shown, the urban crowd monitoring method provided by Embodiment 1 of the present invention includes:

[0048] S110. Acquire original crowd flow data and city grid data, where the original crowd flow data includes a plurality of original trajectory points, and the time intervals between the plurality of original trajectory points are not equal.

[0049] Specifically, the original flow of people data is a plurality of original track points that record the action tracks of people in the city. The format of the original track points is (id, timestep, lat, lon), which is specifically generated by the user id and track points corresponding to the track points. The timestamp (timestep) and the latitude and longitude position (lat, lon...

Embodiment 2

[0059] figure 2 It is a schematic flowchart of a method for monitoring urban crowd flow provided by Embodiment 2 of the present invention, and this embodiment is a further refinement of the foregoing embodiments. Such as figure 2 As shown, the urban crowd monitoring method provided by Embodiment 2 of the present invention includes:

[0060] S210. Acquire original crowd flow data and urban grid data, where the original crowd flow data includes multiple original trajectory points, and the time intervals between the multiple original trajectory points are not equal.

[0061] Specifically, the format of the original trajectory point is (id, timestep, lat, lon), and it is distinguished according to the user id. Then, the format of the original trajectory data of a user is (timestep, lat, lon), which is abbreviated as (t, l ), where t represents the timestamp (timestep), and l represents the latitude and longitude position (lat, lon). The urban grid data is expressed as g m (m...

Abstract

The invention discloses an urban people flow monitoring method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining original people flow data and urbangrid data, wherein the original people flow data comprises a plurality of original track points and the time intervals among the plurality of original track points are unequal, preprocessing the original people stream data based on the city grid data to obtain standardized grid data, wherein the standardized grid data comprises a plurality of standard trajectory points, and the time intervals between the plurality of standard trajectory points are equal, and generating a people flow monitoring view according to the standardized grid data. According to the embodiment of the invention, the influence of uncertain factors such as GPS signals, network signals, equipment power supplies and the like on the generation of the pedestrian flow monitoring view is reduced, pedestrian flow monitoring ismore flexible, professional feature extraction does not need to be manually carried out, the dependence of urban pedestrian flow monitoring on professional technicians is reduced, and the universality of urban pedestrian flow condition monitoring is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of smart cities, and in particular, to a method, device, electronic equipment and storage medium for monitoring urban human flow. Background technique [0002] In the field of smart cities, real-time monitoring and prediction of the flow of people in the city is very important for many urban computing applications (such as dynamic scheduling of public resources, early warning of high-congestion areas, etc.), government transportation departments and location-based service providers in making decisions Two types of information are needed to optimize services and services: the current population distribution and flow situation and the forecast of population flow in the next period of time. [0003] At present, the monitoring of the flow of people in cities requires professionals to extract key information from the collected raw big data of people flow and process it into a form that is ea...
