Problems solved by technology
[0004] Although the use of key point matching can roughly judge human body movements, the recognition granularity is relatively rough, and the attention is focused on human body information while ignoring other objects in the environment, resulting in more misjudgments during the application process; and video analysis will bring more problems. Too much resource consumption will cause the device to freeze and affect normal use

The invention relates to the technical field of artificial intelligence, and discloses a shooting behavior detection method and device, equipment and a storage medium, which are used for improving the accuracy of human behavior recognition. The shooting behavior detection method comprises the following steps: acquiring a single-frame video image of a target person through preset monitoring equipment; performing marker identification on the single-frame video image through a target detection network; if the image acquisition equipment exists in the single-frame video image, performing position correlation detection on the image acquisition equipment and the hands, the side faces and the ears of the target person according to an intersection-to-parallel ratio function; if the image acquisition equipment is in the candidate state, performing perspective transformation on a camera of the image acquisition equipment to generate a corresponding camera perspective transformation plane; and if the included angle between the perspective transformation plane of the camera and the plane of the single-frame video image is smaller than or equal to a preset included angle, determining that the image acquisition equipment is in a shooting state, generating early warning information, and sending the early warning information to an early warning terminal.
Description
technical field [0001] The present invention relates to the technical field of artificial intelligence, and in particular, to a shooting behavior detection method, device, equipment and storage medium. Background technique [0002] With the rapid development of computer vision technology, biometric recognition technology has been extended from face recognition to human behavior recognition. A large number of video and image data collected by cameras are used to identify human behavior, to monitor some illegal behaviors in public places, or It is used in families to prevent dangerous behaviors of the elderly or children. [0003] At present, most of the mainstream behavior recognition methods are based on the human body. First, the human body detection is used to locate the recognition area, and then the key points of the human body are located. According to the key points, it is judged whether the human body posture matches the predefined behavior template to complete the be...
