Because many kinds of dogs have hairs with length or length, the appearance judgment of the dogs is influenced, and the infrared thermal imaging device 32 can more accurately acquire the body contour information of the dogs, so that the reliability of acquiring the information of the dogs is improved, and the dogs can more accurately recognize and judge.

The plurality of cameras 31 and/or the plurality of infrared thermal imaging devices 32 are arranged, so that images of the dog can be acquired from multiple angles, the acquired images of the dog are incomplete or sufficient elements cannot be extracted due to the fact that the dog cannot be guaranteed to be in the most proper position or maintain the most proper posture, the quality of the acquired images of the dog can be higher by acquiring the images of the dog from different angles, and the accuracy of identification verification is higher.

In one example, the computing device 4 may include an image information acquisition module and an information comparison module. And after receiving the dog image, the image information acquisition module performs feature extraction on the dog image to obtain dog information. The information of the dog can include texture information, body shape information, geometric information of facial key points and the like of the dog, and relates to facial contours, facial key point positions, facial lines, body types, foot distances, hair lengths, hair colors and the like. The information comparison module compares the obtained dog information with the registered dog information so as to verify and confirm the identity of the dog. The registered dog information can be stored locally or in the cloud. The submission registration can be a photo of the submitted dog, and the characteristic value information of the registered dog can be identified from the registered photo in advance or in real time and is used for comparing with the characteristic value information of the dog identified from the collected dog image. The dog can be efficiently verified by acquiring information from the image and comparing the information with the information.

In one example, the calculation means 4 sends the result of the determination to the control means 5, and the control means 5 controls the blocking means 2 according to the result of the determination. The control means 5 may be a microprocessor. When the judgment result shows that the dog is only the registered dog, the control device 5 controls the blocking device 2 to allow the passage; when the judgment result shows that the dog is not the registered dog, the control device 5 controls the blocking device 2 to prohibit the passage. The control device 5 may be in communication connection with the driving device of the blocking device 2, such as the brake driving device, the lifting driving device, and the light emitting control circuit in the foregoing embodiments. By controlling the blocking means 2 by the control means 5 an efficient action of verifying the admission or the disallowing of the passage is achieved.

As shown in fig. 3 and 4, in one example, the method may further include: the alarm device 6 provided in the gate case 1, and the control device 5 causes the alarm device 6 to give an alarm when the dog is judged not to be the registered dog.
