All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, an application scenario is schematically shown in the embodiment of the present application. The application comprises a plurality of video acquisition units, each video acquisition unit can acquire stall images in a corresponding area, and then the stall images acquired by each video acquisition unit and the heat information corresponding to each stall are displayed through the comprehensive display interface, so that a plurality of mobile stalls in a target area can be intuitively displayed through the comprehensive display interface, and the heat information of each stall can also be correspondingly displayed, thereby providing reference for a user in purchasing goods. In practical applications, the integrated display interface may be presented via a large display screen at the entrance of the mobile marketplace.
The execution body of the present application may include, but is not limited to, at least one of: user equipment, network equipment, etc. The user equipment may include, but is not limited to, computers, smart phones, personal digital assistants (Personal Digital Assistant, abbreviated as PDA), and the above-mentioned electronic devices. The network device may include, but is not limited to, a single network server, a server group of multiple network servers, or a cloud of a large number of computers or network servers based on cloud computing, where cloud computing is one of distributed computing, and a super virtual computer consisting of a group of loosely coupled computers. This embodiment is not limited thereto. The method comprises the steps S1 to S4, and specifically comprises the following steps:
S1, generating a comprehensive display area corresponding to a target area, and receiving planning information of a management end on the comprehensive display area to obtain first display areas corresponding to video acquisition units in the comprehensive display area and road display areas corresponding to the first display areas.
It will be appreciated that in practical applications, the target area may be relatively large, where there may be many video capturing units, and the location of each video capturing unit may be different, so in order to locate the data captured by each video capturing unit in the target area, the management end may plan the comprehensive display area, so as to obtain a first display area corresponding to each video capturing unit, and a road display area corresponding to the first display area. The video acquisition unit may be a camera.
The first display areas are used for displaying the stall information acquired by the corresponding video acquisition units, and as the road is usually arranged in front of the stall, a corresponding road display area can be arranged for each first display area, so that the heat information of the corresponding stall can be displayed in the follow-up mode through the road display areas.
S2, acquiring standard display images corresponding to the first display areas, which are acquired by the video acquisition units, generating a plurality of stall area lines based on stall identification strategies and the standard display images, positioning the stall area lines into the first display areas, and performing extension processing on the stall area lines to obtain heat area lines corresponding to the stall area lines, and generating comprehensive area lines according to the stall area lines and the heat area lines.
In practical applications, a booth area is usually defined for each booth in a mobile market, so that the mobile booth can sell products in the defined area, the defined booth area may be defined by a yellow box, and after the booth is placed, the dividing line of the booth area may be blocked due to surge of tide.
Therefore, when the information of the booth is collected, the standard display image collected by each video collecting unit can be firstly obtained, the standard display image can be an image shot when no booth or personnel are present, for example, the standard display image can be an image shot when no personnel are present in the daytime, then the booth area line in the standard display image is extracted, and then the area where the mobile booth is located is subsequently locked by the booth area line, so that the booth image in the corresponding area is extracted.
It will be appreciated that the heat of the booth will generally be related to the purchasing customer of the booth, and the customer will generally be standing before the booth to make a line of purchase when purchasing the merchandise, so that after the booth area line is obtained, a corresponding heat area line can be obtained according to the booth area line, and the area where the customer is located is subsequently locked by the heat area line, thereby obtaining the heat information of the corresponding booth.
The specific implementation manner of step S2 based on the above embodiment may be:
s21, acquiring pixel points in a preset stall line pixel value interval in the standard display image as stall pixel points, and acquiring adjacent stall pixel points to generate a plurality of stall pixel point sets.
The pixel value interval of the stall line can be set by a worker in advance according to actual conditions. For example, if the booth line is yellow, the booth line pixel value interval may be a yellow pixel value interval. It will be appreciated that because there may be many booth areas, more than one booth area may be acquired by each video acquisition unit, and that more than one booth pixel set may be generated.
S22, carrying out contour extraction on each stall pixel point set to obtain a plurality of stall area lines, and positioning the stall area lines into the first display area based on the area center point of each stall area line.
It should be noted that the standard display image and the first display area have the same specification. It will be appreciated that since each video capture unit may correspond to more than one booth area line, each booth area line corresponds to a different booth area, after the booth area lines are obtained, the booth area lines may be positioned to correspond to the first display area, such that the location of the booth area lines in the standard display view and the location in the first display area are corresponding.
Specifically, step S22 may be implemented by steps S221 to S223, which are specifically as follows:
s221, carrying out coordinated processing on the standard display image and the first display area, and obtaining a coordinate point at a first preset position in the standard display image as a first coordinate origin and a coordinate point at a second preset position in the first display area as a second coordinate origin, wherein the first preset position and the second preset position are the same.
In practical application, the first preset position and the second preset position may be set by a worker in advance, so that, in order to make the positions of the booth area line in the standard display image and the first display area correspond to each other, the first preset position and the second preset position are identical, so that the coordinate origins of the standard display image and the first display area are also identical.
S222, obtaining the top points of the diagonal lines of each stall area line to generate two diagonal lines, and obtaining the area center point corresponding to the stall area line according to the intersection point of the two diagonal lines.
It will be appreciated that in practice, the booth-defined area of the present solution is a rectangular box, and thus may be obtained by the intersection of the diagonal lines of the booth-defined area when the center point of the booth-defined area is taken.
S223, acquiring a coordinate point corresponding to the region center point in the first display area as a region positioning point, and positioning the stall region line into the first display area based on the region positioning point and the region center point.
By the method, the positions of the stall area lines in the standard display diagram and the positions of the stall area lines in the first display area are corresponding, so that the stall images obtained later can be displayed at the corresponding positions in the first display area.
S23, performing extension treatment on each stall area line to obtain a heat area line corresponding to each stall area line, and generating a comprehensive area line according to the stall area lines and the heat area lines.
When the heat degree area line corresponding to each booth area line is obtained, the method can extend each booth area line, then obtain the heat degree area line corresponding to each booth area line, in some embodiments, the heat degree area line can be obtained through the following steps, and the comprehensive area line is generated through the booth area line and the heat degree area line:
S231, receiving a road center line input by a management end in a road display area corresponding to each first display area, acquiring a direction perpendicular to the road center line as an extending direction, and taking two line segments perpendicular to the road center line in a booth area line as first datum lines, wherein the line segments parallel to the road center line and close to the road center line in the booth area line are taken as second datum lines.
It will be appreciated that customers typically line up in a certain area in front of the booth when they make a purchase, and the road center line may roughly define the above area, and the person located in the area between the road center line and the booth may be considered to be the corresponding queuing person, so that the present solution will make an area determination in combination with the road center line.
Only two area lines of the heat area line can be obtained through the second datum line and the road center line, and a customer can normally make a queue purchase in front of a booth, so that the other two area lines of the heat area line can be determined through the first datum line when determining the other two area lines of the heat area line.
And S232, extending the first datum line to the position of the central line of the road based on the extending direction to obtain two extending lines perpendicular to the central line of the road.
When determining the other two area lines of the heat area line, the first reference line can be extended according to the extending direction, and then two extending lines intersecting with the central line of the road are obtained.
S233, generating a heat degree area line according to the extension line, the road center line and the second reference line, and generating a comprehensive area line according to the booth area line and the heat degree area line.
By the method, the comprehensive area line corresponding to each stall area can be obtained, so that stall information and heat information in each stall area can be intercepted through the comprehensive area line in the follow-up process.
S3, dividing the first display area and the road display area according to the comprehensive area line to obtain a plurality of stall display areas and heat identification areas corresponding to the stall display areas, acquiring current display images acquired by the video acquisition units in real time, and intercepting the current display images according to the comprehensive area line to obtain stall display diagrams and heat display diagrams corresponding to the stall display areas.
When the stall information and the heat information of each stall are displayed through the first display area and the road display area, the first display area and the road display area are firstly divided according to the comprehensive area line to obtain stall display areas for displaying the stall information and heat identification areas for displaying the heat information, then stall display diagrams corresponding to each stall display area and heat display diagrams corresponding to each heat identification area are acquired according to the current display image acquired by the video acquisition unit, the corresponding stall display diagrams are displayed through the stall display areas, the heat information of the corresponding stall is obtained through the heat display diagrams, and then the corresponding heat information is displayed through the heat identification areas.
Specifically, the specific implementation manner of step S3 may be:
s31, dividing the first display area and the road display area according to the comprehensive area lines to obtain a plurality of stall display areas and heat identification areas corresponding to the stall display areas, and configuring corresponding display numbers for the comprehensive area lines.
It will be appreciated that, since there may be multiple integrated area lines, there may be multiple booth display areas and heat identification areas obtained, in order to display corresponding booth display images according to the booth display areas in the following, corresponding display numbers may be configured for each integrated area line, so that corresponding booth display images and booth display areas may be found in the following through the numbers, and the corresponding booth display images may be displayed through the booth display areas.
When the corresponding display numbers are configured for the comprehensive area lines, the comprehensive area lines corresponding to the video acquisition units can be numbered according to the number direction selected by the management end, for example, if the video acquisition units correspond to three comprehensive area lines, the comprehensive area lines can be numbered sequentially according to the number modes of 1, 2 and 3 when the comprehensive area lines are numbered.
S32, acquiring current display images acquired by the video acquisition units in real time, acquiring comprehensive center points of the comprehensive regional lines, determining coordinate points corresponding to the comprehensive center points in the current display images as current positioning points, and positioning the comprehensive regional lines into the current display images based on the current positioning points and the comprehensive center points.
It should be noted that the specifications of the current display image and the first display area are the same, the coordinate origins of the current display image and the first display area after the coordinate processing are the same, the specific determination mode of the coordinate origins is the same as the mode of determining the coordinate origins of the standard display image and the first display area, and the scheme is not repeated here.
It can be appreciated that the current display image is an image acquired after being laid out, and the booth area is consistent with the booth area in the standard display image, so that when determining the booth area in the current display image, the area where the booth is located in the current display image can be positioned according to the comprehensive area line. It should be noted that the video acquisition unit in this scheme is stationary.
