Description

Intelligent pet door based on image recognition and control method thereof Technical Field The invention relates to the technical field of intelligent household equipment, in particular to an intelligent pet door based on image recognition and a control method thereof. Background The pet door is a common facility in modern families, is particularly suitable for families for raising pets such as cats and dogs, provides convenience for the pets to freely enter and exit a specific area, and reduces the interference to the life of the owners. Conventional pet doors are largely divided into two main categories, mechanical pet doors and electronic pet doors. The mechanical pet door usually adopts a one-way or two-way swinging door plate, and the mechanical pet door passes through by virtue of the self thrust of a pet, has a simple structure, can not be selectively controlled, and can possibly enter any animal reaching a certain body shape. The electronic pet door realizes basic access control by technical means, and most commonly is based on radio frequency identification technology. In such a system, the pet wears a collar containing a specific electronic tag, and when the pet approaches, the reader on the door recognizes a valid tag, i.e., unlocks the door. The electronic pet door improves the safety, but has the obvious limitations that firstly, the electronic pet door can not identify the pet, only can identify the necklace, if the necklace is lost, damaged or worn by other animals, the system is invalid or misjudged, and secondly, the electronic pet door can not sense the behavior state of the pet at all, and particularly can not detect whether the pet holds articles in the mouth. One common affliction for feline owners is the natural hunting habit of the cat. Cats often hold captured birds, rodents, etc. prey back into the home, which can not only cause home hygiene problems, raise health risks to pets and owners, but also negatively impact local wild animal protection. There is no commercially available pet door product in the market today that can address the pain of preventing cats from bringing a prey into the room. The prior art does not have the capability of performing real-time and intelligent visual analysis on the mouth area of the pet at all. In recent years, computer vision and deep learning techniques have made breakthrough progress. Convolutional neural networks and the like exhibit performance approaching or even exceeding that of humans in tasks such as object detection, image classification, face recognition, pose estimation and the like. The development of these technologies lays a solid foundation for developing more intelligent perception systems. At the same time, the performance of edge computing devices is continually improving, making it possible to run complex deep learning models on embedded devices that are power-and cost-constrained. This provides a viable technological path for integrating advanced AI vision technology into home internet of things devices. Therefore, a need exists for an intelligent pet door and a control method thereof that can comprehensively utilize modern image recognition and artificial intelligence technology, and in particular can accurately detect and classify the carried objects at the mouth of the pet, thereby realizing intelligent and refined access management, so as to fill the blank of the prior art. Disclosure of Invention In order to solve at least one technical problem in the background art, the invention provides the intelligent pet door based on image recognition and the control method thereof, which solve the key problem that the existing pet door cannot intelligently recognize the carried object at the mouth of the pet and control the door lock according to the carried object, integrate the individual recognition and health state monitoring functions, and realize intelligent and accurate pet access management. The invention solves the technical problems by adopting the following technical scheme: a smart pet door based on image recognition, comprising: the image acquisition device is used for acquiring an image of the pet door region; The artificial intelligent processing unit analyzes the image by adopting a deep learning algorithm and/or a machine learning algorithm and executes the following functions: (a) Identifying the identity of the pet by analyzing the appearance characteristics of the pet; (b) The mouth area analysis comprises detecting whether foreign matters or articles exist in the mouth area, identifying or classifying the foreign matters or articles in the mouth area, and analyzing the form or state change of the mouth area; And the door control device is used for controlling the passing state of the pet door according to the analysis result of the artificial intelligence processing unit. Further, the recognition or classification function in the mouth area analysis divides the detected foreign matters or articles into at least
