Embodiment

[0053] see figure 1 , figure 1 It is a schematic flow chart of a monitoring video-based method for detecting the entry and exit of people provided by the embodiment of the present application. Such as figure 1 As shown, the method includes the following steps:

[0054] S101: Extract video images frame by frame from the real-time monitoring video of the commodity;

[0055] In some embodiments, before S101, the method further includes:

[0056] The background image set by the user is acquired, and the detection area set by the user based on the background image is acquired.

[0057] That is to say, if this method is used for detection for the first time, the user needs to first set a background image and set a detection area within the background image. Among them, the background image is the same light condition selected from the surveillance video (either real-time or historical) and the image in the actual detection without people. The detection area can be the area wher...

Abstract

The invention relates to a personnel access detection method, device and equipment based on a monitoring video. The method comprises the following steps: extracting video images frame by frame from areal-time monitoring video of a commodity; sequentially carrying out foreground detection on a preset detection area in each frame of video image, and calculating to obtain a foreground pixel proportion; if the foreground pixel proportion is greater than a preset first threshold, counting the number of frames of a high foreground image in a first preset number of frames of continuous images; if the frame number of the high-foreground image is greater than a preset second threshold, judging whether a foreground pixel proportion of at least a second preset number of frames of continuous images in the high-foreground image is continuously increased or not; and if so, determining that a person enters a preset detection area. According to the invention, the personnel entry condition in the specific commodity sales area is detected in a foreground detection mode, so that the attention degree of the commodities in the area in the market can be reflected, and the method is simple in detectionalgorithm, small in calculation 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 monitoring video-based method, device and equipment for detecting personnel entering and leaving. Background technique [0002] At present, in retail stores of various commodities, cameras are usually set up to monitor the commodities sold. Firstly, in order to avoid the loss of theft, and secondly, merchants can also use the surveillance video to know which commodities are more concerned, that is, which regions of the commodities It is more attractive for customers to view and contact, thereby improving the accuracy of daily store management, merchandising strategies, and stocking plans. [0003] For the above-mentioned second use, there are several different implementation methods at present. One is artificial statistics method, that is, artificial naked eyes continue to watch the surveillance video, and its disadvantage is that the labor cost is relativ...
