Embodiment

[0061] see figure 1 , figure 1 It is a schematic flowchart of a method for clustering product touch information based on surveillance video provided by the embodiment of the present application. like figure 1 As shown, the method includes the following steps:

[0062] S101: Extract video images frame by frame from the real-time monitoring video of the commodity;

[0063] In some embodiments, before S101, the method further includes: acquiring an initial background image set by the user, and acquiring a detection area set by the user based on the initial background image; based on the user's instruction, if the user chooses to perform an orthogonal projection Transformation, then calculate the projection transformation matrix according to the pixel coordinates of the detection area, and use the projection transformation matrix to perform orthogonal projection transformation on the initial background image set by the user, and use it as the preset background image; if the use...

Abstract

The invention relates to a commodity touch information clustering method, device and equipment based on a surveillance video. The method comprises the following steps of: extracting video images frameby frame from a real-time surveillance video of a commodity; generating a differential gradient image and a binary feature image of a detection area based on a current video image and a preset background image; taking the differential gradient image as a detection image if the number of pixel points of which the pixel values are not zero in the binary feature image is greater than a preset threshold value; counting the touched times of different commodities through an information clustering method based on the detection image; and displaying the touched times in the real-time surveillance video. According to the method, the number of touched times of the commodities in the specific area is recognized in an information clustering mode, so that the attention degree of the commodities in thearea in the market can be reflected, and the method is simple in detection algorithm, small in calculated amount, robust in technology and good in detection effect.

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular to a surveillance video-based product touch information clustering method, device and equipment. Background technique [0002] At present, in retail stores of various commodities, cameras are usually set up to monitor the commodities sold. One is to avoid theft and losses. Second, merchants can also use surveillance videos to know which commodities are more concerned, that is, which commodities have been touched. The number of touches is more, thereby improving the accuracy of daily store management, merchandising strategies, and stocking plans. [0003] For the above-mentioned second use, there are currently several different implementation methods. One is the artificial statistical method, that is, the artificial naked eye continues to watch the surveillance video, and its disadvantage is that the labor cost is high; the other is the image-based object detect...
