Problems solved by technology

[0003] The traditional detection method uses cameras to monitor the factory area in real time, but when detecting personnel, all personnel need to be detected, the detection task is heavy, and it is easy to cause blockage in the detection process. The process is complicated, not intuitive, and cannot meet the needs of users

Abstract

The invention discloses a detection method and device for identifying a personal safety behavior portrait, and the method comprises the steps: carrying out the point set extraction of a dangerous source region in a video image, carrying out the skeleton point set extraction of a person in the video image, and judging whether the person is in the dangerous source region or not; if the person is in the dangerous source area, judging whether the person has a smoking behavior or not; if the person has the smoking behavior, calculating the gradient of a certain pixel point of smoke in the obtained video image of the mouth of the person, and constructing a histogram in the gradient direction based on the gradient of the certain pixel point; and comparing the constructed histogram in the gradient direction with a histogram in a preset smoking smoke histogram database. The smoking smoke histogram database is established based on big data, the obtained histogram of the mouth video image of the person is compared with the smoking smoke histogram in the database, whether the person smokes in the dangerous area or not is determined, the behavior of the person in the dangerous area is detected, and the detection task load can be reduced.

Description

technical field [0001] The invention belongs to the technical field of behavior detection, and in particular relates to a detection method and device based on identifying a person's safety behavior portrait. Background technique [0002] Behavior detection has a wide range of applications in the field of social security, such as abnormal behavior detection in a monitoring environment, theft detection and identification in shopping malls, etc. A chemical plant is a factory engaged in the chemical industry. During the production process of a chemical plant, chemical equipment needs to be manually operated. Due to the strict production safety requirements of the chemical plant, it is necessary to conduct behavioral testing of the personnel in the chemical plant. [0003] The traditional detection method uses cameras to monitor the factory area in real time, but when detecting personnel, all personnel need to be detected, the detection task is heavy, and it is easy to cause bloc...
