Description
[ field of technology ]
The invention relates to an iris recognition technology field, in particular to a method for capturing iris image pictures based on an animal management system.
[ background Art ]
With the continuous improvement of consumer living standard, leisure and recreation have become a part of the life of a wide range of consumers. However, the pet brings endless joy to the pet owner, so that the pet entertainment is already a part of the leisure entertainment of the consumers. At the same time, pets are becoming more and more popular. However, since pets lack effective supervision means for a long time, a certain pressure is brought to supervision departments, pet owners and resident lives. On one hand, the phenomena of loss and abandonment of domestic dogs are greatly increased, and the wandering animals are frightened and even attack citizens, so that the huge risk of spreading infectious diseases such as deadly rabies and the like exists, thereby leading the supervision of pets to become a great difficulty which puzzles urban sanitation, safety, traffic order and environmental management, seriously threatening the benefits of the public and urban construction, and becoming a potential factor influencing the construction of the harmonious society. On the other hand, the pet is lost or stolen, so that huge mental trauma is brought to the pet owner and the family thereof, and particularly, the shadow of the pet owner is difficult to get rid of for a long time for children and the orphan elderly. Part of pet owners spend a great deal of time and money to find lost pets, and the unrestrained pet rescue mechanism and urban management department face the lost pets, but the pet owners cannot be informed in time due to the lack of effective information checking and pet identity recognition means. To solve this social problem, it is necessary to build a pet information management system, and pet identification is a key problem of the information management system. The biotechnological feature identification has the advantages of good safety, no harm, uniqueness and stability, so that the biotechnological feature identification is accepted by wide consumers and pet owners. Biotechnological feature identification refers to the use of physiological or behavioral features of a person or animal to achieve identity identification. The biotechnology characteristic recognition technology mainly comprises face recognition, fingerprint recognition, vein recognition, iris recognition, palm print recognition, voiceprint recognition, gait recognition and the like. The iris recognition technology has extremely high accuracy, high anti-counterfeiting performance and high stability, and is also reliable biotechnology characteristics of acquirability and non-invasiveness, so that the iris recognition technology is valued by people in the world and is rapidly and widely developed and applied. In order to facilitate the management of pets by consumers, an animal management system based on iris recognition is developed later. The animal management system comprises an iris acquisition handset end and a cloud server which is connected with the iris acquisition handset end in real time or used for data exchange in a wireless communication mode. The iris acquisition handset end comprises an acquisition module, a wireless communication module, a processor, an illumination module and an output or input module. The acquisition module acquires iris graphic information from eyes of the pet, transmits the iris graphic information to the inside of the processor after being processed, and transmits the iris graphic information to the inside of the cloud server through the wireless communication module, the cloud server compares and analyzes the newly received iris graphic information with iris graphic information stored in the inside of the cloud server, and if the iris image information is consistent with the iris image information, the newly acquired iris graphic information is updated or modified through the input or output module so as to be convenient for subsequent use. In the acquisition process of the acquisition module, as the photographed pet has the nature of being active, the brain of the pet rotates flexibly and is not easy to control, so that the plane where the eyes of the photographed pet are located and the imaging optical axis of the photographed camera are difficult to control to be mutually perpendicular, and a deviation angle is generated between the plane where the eyes of the photographed pet are located and the imaging optical axis of the photographed camera. If the range of the deviation angle is not in the focal length control range of the iris recognition equipment, the image on the photographed iris image picture is easy to be blurred, and the image blurring information of the iris image picture is easy to cause the recognition precision in the iris recognition process to be lower
