Problems solved by technology

[0003] In the existing technology, the population density calculation method combines qualitative description and quantitative analysis to invert the distribution state of population density in the regional grid, realize the integration of population data, natural resources, environment and other data, and cannot reflect the extremely densely populated areas Due to the unique randomness distribution law of the population distribution in extremely sparse areas and the regional characteristics of the population spatial distribution, the calculation process is too rough, which affects the accuracy and real-time performance of the model

Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 and figure 2 As shown, the embodiment of the present invention discloses a method for estimating urban population density and crowd flow based on smart phones, including the following steps:

[0032] Step 1: Build a graph model: Subdivide the area to be tested into multiple lattices, each vertex in the graph model uniquely represents a lattice, and two adjacent lattices are connected by directed edges, using to indicate the direction of population movement. Specifically, the target region will first be subdivided into smaller areas, namely "lattices", and the graph model will use these lattices as basic units. The graphical model not only visualizes the process of urban crowd flow and the correlation of...

Abstract

The invention discloses a real-time urban population density and crowd flowing estimation method based on a smart phone. Bluetooth (or Wi-Fi) signals sent by adjacent measured mobile phones are scanned by a measuring mobile phone, and MAC addresses, signal intensity and timestamp information of the measured mobile phones are acquired; then data of an accelerometer, a gyroscope and a GPS sensor of the measuring mobile phone and position information of the measuring mobile phone are combined and are packaged to be sent to a central server so as to carry out statistics on the Bluetooth (or Wi-Fi) user number and distribution, and on the basis, population distribution in different regions of a city is determined; and then by combining an urban geographical structure, an urban population density distribution and urban crowd flowing map is generated.

Description

technical field [0001] The invention belongs to the technical field of population density estimation, in particular to a method for estimating urban population density and crowd flow based on smart phones. Background technique [0002] Population is a general term for people living in a specific social system and in a specific region with a certain quantity and quality. Population information is important information on national conditions, which is of great significance to administrative management, population research, understanding market supply and demand, and formulating social and economic development plans. The population problem spans many fields of nature, society and economy, and is one of the major issues facing the world today that affect sustainable development. [0003] In the existing technology, the population density calculation method combines qualitative description and quantitative analysis to invert the distribution state of population density in the re...
