Dog face key point detection method and device based on artificial intelligence, equipment and medium

Abstract

The invention relates to the field of biological recognition in artificial intelligence, and provides a dog face key point detection method based on artificial intelligence, and the method comprises the steps: obtaining a to-be-detected pet dog image and a target key point detection model; inputting the pet dog image into a feature extraction network for feature extraction to obtain a first target feature map, a second target feature map and a third target feature map with different resolutions; respectively inputting the first target feature map, the second target feature map and the third target feature map into a dog-eye key point detection network for processing; respectively inputting the first target feature map, the second target feature map and the third target feature map into a dog nose key point detection network for processing; determining a target dog-eye key point group according to the first confidence coefficient; and determining a target dog nose key point group according to the second confidence coefficient. The method improves the detection accuracy of the key points of the dog face. The invention further relates to a block chain technology, and the target key point detection model can be stored in a block chain.

Description

technical field [0001] The present application relates to the field of biometrics, and in particular to an artificial intelligence-based key point detection method, device, equipment and medium for dog faces. Background technique [0002] At present, users can purchase pet insurance for their pet dogs. When their pet dogs get sick or have accidents, they can apply for compensation from the insurance company, which can protect the safety of pet dogs and reduce their own economic losses. When the pet dog is insured, the identity authentication of the pet dog is required. Existing methods such as DNA authentication and chip authentication are complicated to operate and costly. In order to solve the above problems, it is possible to detect the key points of the pet dog, and then collect and store the characteristic information of the pet dog based on the dog's facial recognition technology through the key points of the dog's face, so as to realize the identity authentication of...
