Problems solved by technology

However, most of the existing methods only draw the trajectory curve of people’s movement according to the trajectory of people’s actions. On the one hand, the time dimension is long, and the displayed trajectory curve is very messy. Therefore, in most cases, it is only possible to roughly estimate the flow of people. It is difficult to clearly obtain the specific information of the flow of people; on the other hand, when the flow of people is large, the trajectory curves displayed are very many and messy. Due to the limited display interface of mobile phones and tablets used in daily life, it is difficult to achieve the overall flow of people The visual effect requires repeated sliding of the interface, resulting in a very poor user experience

Embodiment 1

[0032] refer to figure 1 As shown, Embodiment 1 of the present invention provides a method for analyzing flow of people based on direction aggregation, which includes the following steps:

[0033] In step 101, a coordinate system is established, and the obtained target pictures are synthesized on the coordinate system to generate a person's trajectory, and the discrete points on each person's trajectory are fitted to form a straight line.

[0034] For example, the key frame of the image data collected by the camera can be extracted, wherein the key frame can be any frame in the image data collected in real time, or a specified frame that meets the preset requirements, for example, it can clearly reflect Whether there is a frame of people flow, so that the image of people flow at the location shot by the camera can be obtained, and then the image on the picture is preprocessed through the reshape function to obtain a standardized picture as the target picture. Among them, the ...

Embodiment 2

[0060] Considering that the display interfaces of mobile phones and tablets used in daily life are relatively small. Therefore, Embodiment 2 of the present invention provides a method for analyzing human flow based on direction aggregation, which includes the method steps in Embodiment 1 above, and the same method steps use the same reference numerals, and this embodiment will not be repeated here. However, the difference is that referring to Figure 10 As shown, this embodiment also includes step 103. In step 103, after the straight lines with similar directions in the dynamic region are merged twice, the system defines and filters out some dynamic lines or dynamic offset lines with smaller weight values.

[0061] For example, after secondary merging, if the amount of data is too large, there will still be a lot of routes (here refers to dynamic lines and dynamic offset lines). If you use a mobile device with a relatively small display interface to view, you still cannot Ver...

Abstract

The invention discloses a method for analyzing people flow based on direction aggregation and a medium, on which a computer program is stored. When the program is executed by a processor, the steps of the method for analyzing people flow based on direction aggregation are realized. The method includes: establishing a coordinate system , synthesize the obtained target pictures on the coordinate system to generate character trajectories, and fit the discrete points on each character trajectory to form a straight line; divide the synthesized target pictures into multiple dynamic regions, and dynamically The straight lines with similar directions in the area are merged multiple times to finally generate the traffic flow analysis interface. The present invention fits the trajectory curves of the characters to form a straight line, divides the dynamic area scientifically and rationally, merges the straight lines with similar directions in the dynamic area multiple times, sorts and analyzes the direction of the flow of people in the overall area, and provides it to the user as a reference , Through the statistics and analysis of traffic data, we can use our own resources more scientifically and rationally to increase efficiency.

Description

technical field [0001] The invention relates to the technical field of people flow statistics and analysis, in particular to a people flow analysis method and medium based on directional aggregation. Background technique [0002] People flow statistics are carried out in public places such as intersections, banks, and shopping malls. People flow statistics can be used as an important basis for construction, management, and decision-making. For example, through the statistics and analysis of people flow data, we can arrange traffic more scientifically and rationally. Facilities, bank security management, decision-making mall marketing methods, etc. The commonly used method for counting the flow of people in the prior art is mainly to count the flow of people through monitoring video analysis technology. However, most of the existing methods only draw the trajectory curve of people’s movement according to the trajectory of people’s actions. On the one hand, the time dimension...
