Detailed Description
The present application is described in further detail below with reference to figures 1-6.
The embodiment of the application discloses an intelligent exhibit display method based on data analysis. Referring to fig. 1, the intelligent exhibit display method includes the following steps:
101. and detecting the face information of the visual area of the exhibit.
The face information detection adopts a face capturing technology, which is a mature technical means and is not further described in this embodiment.
The visual area of the exhibit comprises an area right above the exhibit and front, back, left and right areas which are a first distance threshold value away from the center of the front of the exhibit, and specifically, the center of the front of the exhibit is the center of the front of the exhibit placed on the display counter. One exhibit corresponds to one visual area, and the front, back, left and right areas of the exhibit are circular areas relative to the front of the exhibit directly above the exhibit. After the visitors enter the visible area, the visitors can start to see the exhibits.
The first distance threshold is a preset value, and is determined by the actual occupied space of the display counter, the exhibit, the exhibition hall or the exhibition area, and the like, namely, the size of the first distance threshold changes along with the change of the actual situation.
It should be noted that different exhibits have their own independent numbers.
102. And after the face information is detected, starting to record time until the visible area of the exhibit loses the face information, and obtaining a visiting time period.
The visiting time period is a time period from the detection of the face information to the disappearance of the face information, the face information disappears, that is, the face cannot be captured, and at this time, the observer may be still in the visible area of the exhibit, but the face of the observer deviates from the visible area.
103. And judging the face angle according to the detected face information.
The face angles include an overlook face, a left side face, a right side face, and a head-up face. The visitor's line of sight has begun to deviate from the exhibit when the face angle is left or right, and remains on the exhibit when the face angle is top or head-up.
104. And storing the visiting time period, the corresponding visiting face information and the exhibit number.
The visiting time periods, the corresponding visiting face information and the corresponding exhibit numbers are used for being visually displayed in a report form, one visiting time period corresponds to one piece of visiting face information and one exhibit number, and the visiting face information comprises the change sequence of face angles.
If the number of the exhibited exhibits is multiple, the human face information detection is carried out on the visual areas of the exhibits at the same time, then the human face information of each exhibit is processed respectively, and the visiting time period, the visiting human face information and the exhibit number of each exhibit are obtained.
It should be noted that, after the step 101 is executed, the step 102 may be executed first, then the step 103 may be executed, and finally the step 104 may be executed; or step 101, step 103, step 104 and step 104 may be executed first; step 101 may be performed first, then step 102 and step 103 may be performed simultaneously, and finally step 104 may be performed. Even if the steps 102 and 103 are performed in the order of front and rear, the interval time between front and rear does not exceed 1 second.
Referring to fig. 2, in more detail, step 101 includes steps 1011 to 1013:
1011. and acquiring the distance information between the visitor and the display counter in real time.
The distance information is converted into binary codes through operations of complement, mask, coding and the like.
1012. Based on the second distance threshold, if the distance information is smaller than the second distance threshold, the display counter is close to the person, and if the distance information is not smaller than the second distance threshold, the display counter is close to the person.
The second distance threshold is a preset value, and when the distance between the visitor and the display counter is smaller than the second distance threshold, the visitor enters the visual area of the exhibit.
1013. And if a person approaches the display counter, the face information detection is carried out on the visual area of the exhibit.
If only visitors are close to the display counter, the human face information detection is started to be carried out on the visual area of the exhibit, and if no person is close to the display counter, the step 1013 is not executed.
Referring to fig. 3, in more detail, step 103 includes:
1031. and after the face information is detected in the visual area of the exhibit, acquiring the image information of the visual area at intervals of time T.
And only when the face information is detected in the visible area of the exhibit, the image information of the visible area is acquired, namely the face information of the visible area disappears, and the image information of the visible area is not acquired. The time period T is a preset value and varies with actual needs.
1032. And processing and analyzing the image information to obtain an image area of the human face.
The processing and analyzing of the image information are common technical means in the image processing technology, and will not be further described in this embodiment.
1033. And identifying the image area of the face to obtain the five sense organs contained in the image area of the face.
The identification of the image area of the human face is a common technical means in the image processing technology, and the embodiment is not further described.
1034. And judging the five sense organs contained in the image area of the human face, wherein if the five sense organs do not contain the complete right eye, the five sense organs are the right side face, if the five sense organs do not contain the complete left eye, the five sense organs are the left side face, and otherwise, the five sense organs are the full face.
When the image area of the face does not contain the complete right eye or left eye, the visitor is in a head-off state in the visible area, and the sight line of the visitor is not concentrated on the exhibit or is not completely concentrated on the product.
1035. If the face is a full face, the image information is recognized, if the face contains the top of the head, the face is a overlook face, and if the face is a head-up face, the face is not a head-up face.
