Abstract
Description

[0002] At present, customer flow counting equipment tracks the same person as the same ID based on an algorithm, and then determines whether the person enters or leaves the store; it can count the number of people entering and leaving the store, and can also display the number of people entering and leaving the store on the preview interface, and intuitively display the current number of people entering and leaving the store.
[0003] However, the above process only counts customer flow status for three status labels: entering the store, leaving the store, and wandering, which does not fully capture customer trajectory behavior.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0056] To facilitate understanding of this embodiment, the embodiment of the present invention is described in detail below.
[0057] Example 1:
[0058] Figure 1 This is a flow chart of the method for accurately counting passenger flow provided in Example 1 of the present invention.
[0059] Reference Figure 1 , the method comprises the following steps:
[0060] Step S101, obtaining the set off-store area;
[0061] Step S102, calculating the store area based on the store area;
[0062] Here, the in-store area is automatically calculated based on the out-store area, avoiding tedious operations for customers.
[0063] Step S103: Acquire alarm information, parse the alarm information, and obtain a Json package body; wherein the Json package body includes the coordinates of the human figure;
[0064] Step S104, determining the appearance point, vanishing point, and middle point of the human figure coordinates based on the area outside the store and the area inside the store;
[0065] Step S105, determining the trajectory label of the passenger flow according to the appearance point, vanishing point and middle point;
[0066] Among them, the trajectory labels include entering the store, leaving the store, entering and exiting the store, same side and passing the store.
[0067] In this embodiment, the status labels of human-shaped trajectories are enriched, covering the basic human-shaped trajectories, scientifically and reasonably marking the human-shaped trajectories entering and leaving the store, and the setting is simple. By setting the out-store area, the in-store area is automatically calculated based on the out-store area; then the trajectory labels of the customer flow are automatically calculated based on the human-shaped coordinates, which can cover the movement trajectories of people inside and outside the store; this application can also package pictures and alarm information and upload them to the cloud server, where they are intuitively displayed, framing the human figure and displaying each person's movement trajectory and status label.
[0068] This application can directly count the number of people entering and leaving the store, and can intuitively see the movement trajectory of each person, which greatly facilitates the store owner to understand the situation of entering and leaving the store, and facilitates the store owner to review the customer's walking records. In addition, the cloud server can also filter all alarms according to the unified trajectory status and display alarms with the same trajectory.
[0069] Further, refer to Figure 2 , step S102 includes the following steps:
[0070] Step S201, obtaining the store line CG of the store exterior area and the image area captured by the camera;
[0071] Step S202, calculating the slope of the store line CG;
[0072] Step S203, obtaining a first straight line H and a second straight line J with slopes perpendicular to the store line CG;
[0073] Step S204, calculating the intersection points of the first straight line and the second straight line with the coordinate system; wherein the intersection points include the first intersection point and the second intersection point;
[0074] Specifically, according to the slope of the store line CG, a first straight line H and a second straight line J are drawn perpendicular to the two points CG; the two straight lines intersect with the coordinate system, and the intersection points D and E with the coordinate system are calculated.
[0075] Step S205: Obtain the set exclusion rules; wherein the exclusion rules include: excluding points whose coordinates are less than 0, excluding points on the same side as the area outside the store, and excluding points not on the screen area;
[0076] Step S206: The intersection of the store area A, the coordinate system, and the screen area is obtained by applying the set exclusion rule to obtain the first intersection point D and the third intersection point F;
[0077] In step S207 , the in-store area B (ie, CDEFG) is obtained according to the first intersection point D, the third intersection point F, the slope CG of the store line, and the second intersection point E.
[0078] Furthermore, the appearance point is the first time that the human figure coordinates appear in the off-store area A, the in-store area B or other areas C; the vanishing point is the last time that the human figure coordinates appear in the off-store area A, the in-store area B or other areas C; the intermediate point is whether the human figure coordinates pass through the off-store area A or the in-store area B in the process between the appearance point and the vanishing point; among them, the other areas C are areas other than the off-store area A and the in-store area B.
[0079] Furthermore, step S105 includes the following steps:
[0080] Step S301: When the appearance point is in the area outside the store or other areas, and the disappearance point is in the store area, the movement trajectory is entering the store;
[0081] Step S302: When the appearance point is in the store area and the disappearance point is outside the store or other areas, the movement trajectory is leaving the store;
[0082] Step S303: When both the appearance point and the vanishing point are outside the store area and intersect with the area outside the store, the movement trajectory is a passing store;
[0083] Step S304: when the middle point intersects with the store area after passing through the store, the movement trajectory is in and out of the store;
[0084] Step S305: When the appearance point and the vanishing point are both in the store area, the movement trajectory is on the same side.
[0085] Specifically, according to the above logic, the area where the appearance point appears, the area where the middle point appears, and the area where the vanishing point appears are determined, and different trajectory labels are obtained by comprehensive calculation, such as entering the store, leaving the store, passing the store, entering and exiting the store, and on the same side.
[0086] Furthermore, the method further comprises the following steps:
[0087] Step S401, aggregating all images of the same person into a motion trajectory;
[0088] Step S402: Check the movement path of the same person based on the movement trajectory.
[0089] Specifically, the algorithm tracks the same human figure and aggregates them into the same ID (this ID is the human figure ID, representing the same person); then all pictures of the same person are aggregated into tracks, so that the person's movement path can be clearly seen; finally, by intuitively displaying the continuous movement track of the same human figure ID, customers can clearly see the walking track of the same person, which is convenient for management.
