The technology of facial recognition has made it very easy to access devices thanks to being able to automatically identify a person. This is possible thanks to an analysis of their facial features. This type of identification has also reached pets.
The system Petvation is a smart pet door that only allows entry to animals that are properly identified. Therefore, pets can come and go as they please but It prevents other unwanted animals from invading the house very easily.
Only identified animals will enter the home
This security system not only manages to identify traditional pets such as dogs or cats, but can also recognize other domestic animals such as ducks, turtles, snakes or even foxes.
This door is installed in one of the exterior doors of the house. Infrared cameras are positioned above the unit on both sides of the access point, with 120 degree lens that provide a wide field of view to monitor activity from the front and built-in night vision lights for day and night operation.
The developers are aware that facial identification and authentication of animals is more difficult than that of humans, so they have had to use the recognition of the whole body of the animal through multiple images.
The artificial intelligencewhen the animal is in front of it, it executes the recognition algorithms in order to identify the subject. If the animal is inside the system because it belongs to the family, it can enter. If it is an intruder like a raccoon or a rat, the door will remain closed.
If the animal that wants to enter is correctly identified the Petvation door slides up to allow entry, and then slides back to cut off the entry point of everything behind.
The animal is safe, the door will not hurt him
This gate uses three independent safety mechanisms to protect the animal from head to tail.
First, the sensors detect and control when an animal approaches and passes without major difficulties.
There is also a mechanism It prevents any part of the body from getting trapped. This system is light based to ensure paws or tails are not hit by the door falling, so it is impossible for the gate to lower at the moment an animal passes through it.
the third system checks the status of all door sensors during operation and enter safe mode if problems are detected. If this occurs, the person responsible for the problem will be informed through a mobile app.
This app is also used for configuration and control. Therefore, curfews can be established, the authorization of specific pets and the tracking of the comings and goings of the animals in the house. In addition, it also allows you to open and close the door manually remotely.
How facial recognition works in humans
1. Face recognition
The camera detects and locates the image of a face. The image can show the person from the front or in profile.
2. Face analysis
An image of the face is then captured and analyzed. Most facial recognition technology relies on 2D rather than 3D images, since a 2D image can be more easily compared to public photos or photos in a database.
The software read the geometry of the face. Key factors include the distance between the eyes, the depth of the eye sockets, the distance from the forehead to the chin, the shape of the cheekbones, and the contour of the lips, ears, and chin.
3. Image to data conversion
The face capture process transforms analog information (a face) into a set of digital information (data) based on the person’s facial features.
Basically, face analysis becomes a mathematical formula. The numerical code is called a face print. In the same way that fingerprints are unique, each person has their own facial print.
4. Search for a match
The facial print is compared to a database of other known faces. If the facial print matches an image in a facial recognition database, then a determination will be made.
