Problems solved by technology

At the same time, since the GPS signal can only be obtained outdoors, it can only identify the outdoor stay points; while the recognition results of mobile phone cellular information have a large granularity and errors, and it is difficult to accurately identify the travel stay points
At the same time, for specific situations such as GPS drift, the above methods also have serious deficiencies, which pose a great challenge to their practicability

Embodiment 1

[0075] Embodiment 1 of the present invention provides a method for identifying stop points based on multi-motion parameters. The collection point is stored after being marked as a GPS positioning type or a network positioning type, such as image 3 As shown, the method includes:

[0076]In step 201, when it is judged that the positioning type of the current collection point is the network positioning type, the collection points within the preset time length t1 are acquired; wherein, the collection points within the preset time length t1 include collection points of the GPS positioning type and / or network positioning type Collection point.

[0077] Wherein, the current collection point may be the positioning point collected by the terminal in real time; or it may be the positioning point selected from the historical collection points in the later analysis process for analysis and determining whether it is a stay point.

[0078] Among them, the preset duration t1 can be 1-5 min...

Embodiment 2

[0103] In Embodiment 1, when the collection point is a network positioning type, a corresponding processing flow is described. However, the embodiment of the present invention explains the corresponding processing flow when the collection point is of GPS positioning type. Such as Figure 5 As shown, the embodiment of the present invention proposes a method for identifying a stay point based on multi-motion parameters. The collection point is stored after being marked as a GPS positioning type or a network positioning type. The method includes:

[0104] In step 401, when it is judged that the positioning type of the current collection point is GPS positioning type, a set consisting of GPS positioning type collection points within a preset time length t2 is acquired.

[0105] Wherein, the current collection point may be the positioning point collected by the terminal in real time; or it may be the positioning point selected from the historical collection points in the later ana...

Embodiment 3

[0129] Provide a kind of stay point identification method (network positioning type side) based on multiple motion parameters described in embodiment 1 and a kind of stay point identification method (GPS positioning type side) based on multiple motion parameters described in embodiment 2 Finally, in the embodiment of the present invention, a method for identifying the stay point based on multiple motion parameters is also proposed. The embodiment of the present invention integrates the methods in Embodiment 1 and Embodiment 2 into a complete model for illustration. In the embodiment of the present invention, the collection point can be stored on a terminal (for example: smart devices such as a mobile phone, a bracelet, and a tablet), or can be stored on a server. Corresponding to each collection has its own positioning type, the terminal periodically judges the state of the collection point, such as Figure 7 As mentioned, the methods in the model include:

[0130] In step 60...

Abstract

The present invention belongs to the intelligent terminal technical field and provides a multiple-motion parameter-based stay point recognition method and apparatus. The method comprises the following steps that: when it is judged that the positioning type of a current acquisition point is a network positioning type, acquisition points within a preset time period t1 are obtained; the proportion and positioning accuracy value change degree of network positioning type acquisition points in the acquisition points are put into statistics; and if the proportion of the network positioning type acquisition points is larger than a preset network proportion threshold value, and the positioning accuracy value change degree of the network positioning type acquisition points is smaller than a preset accuracy threshold value, it is judged that the current acquisition point is a stay point. According to the multiple-motion parameter-based stay point recognition method and apparatus provided by the embodiments of the invention, the proportion sum of the network positioning type acquisition points is utilized to determine whether the current terminal enters a region with a GPS signal shielding characteristic; and the last GPS effective point of a user when the user enters an indoor environment is adopted as the practical position of the stay point on the basis of a principle that the GPS is switched to network positioning when the user enters indoor environment, and therefore, the problem of low accuracy in the prior art can be solved.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of intelligent terminals, in particular to a method and device for identifying a stop point based on multiple motion parameters. [0003] 【Background technique】 [0004] Questionnaire surveys and telephone interviews are the main methods for traditional surveys of residents’ travel, but they have high survey costs, heavy workload, long data collection and processing cycles, survey content is affected by subjective consciousness, and survey data is inaccurate. It is always hoped that they can be resolved. key issues. [0005] With the development of information technology, in recent years, there has been a method of using information equipment to record user travel trajectories and identify stop points, which is used to replace traditional travel survey methods. Because these methods overcome the problems of high cost of traditional paper and telephone interviews, doubtful feasibility and low...
