Embodiment 1

[0066] figure 1 It is a flow chart of an image recognition-based retrograde judgment method provided in Embodiment 1 of the present invention. As shown in the figure, the retrograde judgment method based on image recognition specifically includes:

[0067] Step S101: Acquiring video data of the escalator area in real time.

[0068] The escalator area refers to the area where escalators are installed in public places. Generally speaking, two escalators are installed in an escalator area to transport passengers in two directions. between). Of course, according to the actual passenger transportation needs and the specific design of public places, one escalator area may also be installed with one escalator or more than two escalators, and the two escalators in an escalator area may also run in the same direction. In order to ensure the normal operation of the escalator and avoid equipment failure and stampede incidents caused by disorderly behavior in public places, there are s...

Embodiment 2

[0081] figure 2 It is a flow chart of an image recognition-based retrograde judgment method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments.

[0082] Specifically, refer to figure 2 , the retrograde judgment method based on image recognition provided in this embodiment specifically includes:

[0083] Step S201: Acquiring video data of the escalator area in real time.

[0084] Step S202: Detect the head region in the video data.

[0085] Specifically, the detection of the head area in the video data needs to detect the head area in each frame of the video data and the head orientation in the head area. The head orientation is detected by a head orientation classifier, and the head orientation classifier is obtained by training the escalator sample image data through a preset convolutional neural network.

[0086] Specifically, the preset convolutional neural network includes sequentially conne...

Embodiment 3

[0109] Figure 4 It is a schematic structural diagram of an image recognition-based retrograde judging device provided in Embodiment 3 of the present invention. refer to Figure 4 , the image recognition-based retrograde judging device includes: a video data acquisition unit 301 , a head region tracking unit 302 , a head number judging unit 303 , a first retrograde judging unit 304 and a second retrograde judging unit 305 .

[0110] Wherein, the video data acquisition unit 301 is used to obtain video data of the escalator area in real time; the head area tracking unit 302 is used to detect the head area in the video data, and perform target tracking on the head area to obtain the head area. direction of movement; the head number judging unit 303, configured to confirm whether the number of the head regions is greater than a preset threshold; the first retrograde judging unit 304, used to determine if the number of the head regions is greater than a preset threshold value, ac...

Abstract

The embodiment of the invention discloses a retrograde judgment method and device based on image recognition, equipment and a storage medium. The method comprises the following steps: acquiring videodata of an escalator area in real time; detecting a head area in the video data, and performing target tracking on the head area to obtain a head movement direction; determining whether the number ofthe head areas is greater than a preset threshold value or not; if the number of the head regions is greater than a preset threshold value, determining a retrograde state according to a proportional relation between the number of the head regions in different motion directions and the number of the head regions; and if the number of the head areas is smaller than or equal to a preset threshold value, carrying out escalator streamer tracking on the video data to obtain the movement direction of an escalator, and determining the retrograde state according to the movement direction of the escalator and the movement direction of the head. The result of target detection based on the head area is accurate, and accurate retrograde detection and alarm can be realized by selecting different retrograde references according to the number of passengers.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of public services, and in particular to image recognition-based retrograde judgment methods, devices, equipment, and storage media. Background technique [0002] With the acceleration of the urbanization process, the proportion of urban population is getting higher and higher, and the population of big cities is increasing. The rapid development of urban public services, such as subways, shopping malls, and airports, is also developing simultaneously with population changes. In order to provide efficient and fast personnel gathering and distributing solutions in crowded public places, escalators are widely used because of their uninterrupted operation. However, in addition to the safety hazards caused by equipment failures on the escalators where passengers are concentrated, there are also safety hazards caused by passengers not observing public order (such as retrograde) during the es...
