Problems solved by technology

The ignition point of many combustible substances is mostly below the surface temperature of the cigarette butt, such as paper at 130°C and pine wood at 250°C. If the cigarette butt is not extinguished, there is a safety hazard of fire.

Embodiment 1

[0038] In order to achieve intelligent monitoring and identification of illegal smoking behaviors in public no-smoking areas, maintain public health, and ensure public safety, the embodiment of the present invention provides a method for identifying smoking based on video images, mainly using video surveillance cameras that are widely covered in cities. Video collection is carried out in the area, and the smoking identification method provided in this embodiment is used to realize the monitoring, identification and early warning of illegal smoking behaviors.

[0039] See figure 1 , figure 1 A schematic flow chart of a method for identifying smoking based on video images provided in this embodiment, the method mainly includes the following steps:

[0040] S101. Obtain a surveillance video to be tested, extract key image frames, and perform human body posture feature extraction on the key image frames.

[0041] In this embodiment, image frames are extracted from the surveillan...

Embodiment 2

[0058] On the basis of the first embodiment above, this embodiment provides a device for identifying smoking based on video images, please refer to Figure 5 , the device mainly includes the following modules:

[0059] The image acquisition and processing module 51 is used to acquire the surveillance video to be tested, extract key image frames, and perform human body posture feature extraction on the key image frames.

[0060] Optionally, the image acquisition and processing module 51 is configured to extract image frames from the surveillance video to be tested as key image frames according to a set extraction interval.

[0061] Optionally, the image acquisition processing module 51 is used for character feature recognition on the currently extracted key image frame, if it is judged that there is a character feature in the currently extracted key image frame, then the extraction interval of the next key image frame is adjusted to the current The extracted key image frame is...

Abstract

The invention provides a method and device for identifying smoking based on a video image, a server and a storage medium, and the method comprises the steps: obtaining a to-be-detected monitoring video, extracting a key image frame, and carrying out the human body posture feature extraction of the key image frame; identifying the to-be-detected monitoring video by utilizing the smoke identification model to judge whether smoke exists or not; utilizing a posture recognition model to recognize the extracted human body posture so as to judge whether a specific human body posture matched with theextracted human body posture exists in a posture library or not; if the smoke recognition model outputs that smoke exists and the posture recognition model outputs a recognition result that a specifichuman body posture exists, determining that a smoking event exists. According to the method and device, smoking events are monitored and recognized in time, the method and device can be widely applied to no-smoking areas such as schools, shopping malls, factories and urban public transportation places, rapid, real-time and online intelligent recognition and monitoring of illegal smoking behaviorsare achieved, public health maintenance is facilitated, public safety is guaranteed, and civilized cities are established.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a method, device, server and storage medium for recognizing smoking based on video images. Background technique [0002] Smoking refers to the behavior of the human body inhaling the gas produced by burning tobacco through the mouth. It is an unhealthy living habit. Cigarettes not only contain nicotine but also polonium 210. Long-term smoking can lead to incurable diseases such as bronchitis and cancer. [0003] Second-hand smoke, also known as passive smoking and environmental tobacco smoke, refers to the mixed smoke formed by the burning end of cigarettes or other tobacco products and the tobacco smoke exhaled by smokers. It is also the most widespread and serious form of indoor air pollution and a leading cause of death worldwide. Studies have pointed out that second-hand smoke contains more than 4,000 harmful chemicals such as tar, ammonia, nicotine, suspen...
