When it comes to face recognition, I think everyone is familiar with it, especially in this special period of this year, when logging in to various travel systems and private software, face recognition functions are needed. But after some use, the restrictions are still quite large. For example, the face must be within the set frame, you may blink and open your mouth according to the prompt, and you must face the camera directly. Doing these actions in a crowded place is actually quite embarrassing. But I have to say that this is the most common status quo of the "face recognition" function.
However, the owner of Cadillac XT4 doesn't need to do this at all, because Cadillac XT4 adopts an infrared binocular camera face recognition scheme. The face recognition function mentioned above, which needs to do various actions, uses a monocular camera scheme. The experience between the two is worlds apart.
The photo can't be unlocked.
This starts with Cadillac's infrared binocular camera. The principle of infrared binocular camera is to use infrared emitter to illuminate the face. After the face reflects infrared light, the infrared camera collects information to identify the face. Because the face is a solid geometric thing, the reflected light has a time difference. The algorithm can get the information of the face at the "depth" level according to the time difference, and restore a 3D solid geometric object.
What good is this? First of all, we don't need to worry about others taking our photos to unlock the vehicle, because in the eyes of infrared cameras, the photos are just a plane, not a three-dimensional geometry. Secondly, we don't have to make faces like a monocular camera to unlock the vehicle. That anti-theft scheme is not only embarrassing, but also inefficient. It is best to open the vehicle with a key.
At the same time, you don't have to stare at the camera seriously, you can also identify and unlock it from different angles, which is simple, easy and random. When you are in a hurry to get on the bus in some unexpected situations, when others are still rummaging through the keys in the bag, or losing the password, or staring at the camera waiting for identification, you have already got on the bus first, started the vehicle and left.
In our daily life, many female friends make up. After wearing makeup, the whole person looks different. However, the owners of Cadillac XT4 don't have to worry that they won't recognize what beautiful makeup they put on today. Cadillac XT4 is very loyal to the Lord. As long as your makeup doesn't change the physical structure of your face, whether the owner wears plain makeup or smoky makeup, it will still be correctly recognized. So the owner of Cadillac XT4 is responsible for beauty.
The face recognition function is really easy to use, and the professor likes fresh functions. However, before the test drive, vehicles equipped with similar functions are particularly afraid of encountering bad surrounding environment, especially in underground parking lots, which are often difficult to identify due to dim lighting. Moreover, in rainy and foggy weather, the recognition rate will also decrease. Imagine that the mobile phone face recognition system, which is already a cutting-edge technology, often falls off when the environment is poor, such as darkness and cars are hard to avoid.
Unlock outdoors during the day.
Unlock indoors at night
But Cadillac XT4 can avoid this situation. Because the Cadillac XT4 camera has an infrared emitter, which is an infrared bulb, the face recognition system of Cadillac XT4 can still work normally whether it is day or night, sunny or cloudy, indoors or outdoors. Take the most common car environment, such as the underground parking lot or at night, the light is very dark. We tested the face recognition system of Cadillac XT4 in sunny outdoor and dimly lit indoor. There is no obvious difference in the experience of the system under two lighting environments.
In real life, you will often encounter the situation that the weather changes suddenly and the rain pours down. When you get on the bus in a hurry, if you still need to take out the key, you have become a drowned rat. But the owner of the Cadillac XT4 won't. As long as his face is put together, he can unlock it immediately and drive away.
Another advantage of using infrared recognition is that it is not afraid of interference. If the spectrum is divided, the visible region consists of red, orange, yellow, green, blue, indigo and purple. Light waves with shorter wavelength than purple are called ultraviolet rays, and light waves with longer wavelength than red are called infrared rays. Most artificial light sources are in the visible region, and infrared face recognition can avoid the interference of visible light.
Although we usually don't pay much attention, we are in a very complicated lighting environment. For example, when we are in an indoor parking lot, we are likely to be illuminated by yellow halogen lights or white LED lights. Therefore, XT4 does not adopt the color light recognition scheme to prevent the recognition rate from decreasing.
The face recognition system of Cadillac XT4 has a wide range of applicability. No matter day or night, no matter how bad the surrounding environment is, it can identify the owner. What if people are "bad"?
Many Cadillac owners love sports. Football, basketball and even extreme sports such as rock climbing and skiing will be involved, and scratches will inevitably occur. If you accidentally hurt your face and need to wrap gauze, then face recognition may not work.
Fortunately, Cadillac XT4 has prepared a variety of wake-up/unlock modes for this system, and the owner can wake up the system through fingerprint sensing buttons, driver's seat door handle buttons and mobile phone Bluetooth. The vehicle is unlocked by three unlocking methods: face recognition/face recognition+password/fingerprint unlocking+password. Therefore, even if you are injured in sports, you don't have to worry that you can't use the keyless entry/start function.
In real life, professors often encounter such a situation. Both husband and wife have a key in the car, but because of the nature of their work, they often travel on business, but they often forget to leave the key. At this time, parents will face the situation that the car can't be used when they pick up their children for school. They can only send their children to school on a small electric donkey. When it is windy and rainy, it is not only embarrassing, but also a lot of motor vehicles on the road.
Multi-account management system
Cadillac XT4 can completely avoid this embarrassment, because its face recognition system has 8 buttons, 1 main and 7 pairs. The master administrator can authorize seven ordinary users to unlock the vehicle. Even in the above situation, parents at home can take the car away.
Although Cadillac XT4 can support multi-person sharing, there is no need to worry about its system security. Through the local system of the original car and the encryption chip of the closed port, the triple privacy protection is destroyed and maintained to ensure that the information is not leaked. The security hardware also adopts anti-theft and anti-disassembly design, which will automatically lock in case of suspicious circumstances. Because the data is not networked, it can't be hacked, and violent disassembly will encounter automatic locking, so Cadillac XT4 can be said to be neither soft nor hard.
After a day's trial, we found that the face recognition unlocking and starting system of Cadillac XT4 is perfect. It adopts an infrared binocular camera scheme with higher cost and more mature technology, so we don't have to worry about being stolen or not recognizing it after makeup. This scheme can still ensure the accuracy and sensitivity of the system in various scenarios, and also solve the problem of only two keys.
Cadillac XT4 applies the face recognition unlocking and starting system to cars. This forward-looking configuration can bring car owners a face-brushing experience and a more convenient travel experience. I believe this system will become the standard for all cars in the future, because really, whoever uses this system will say yes.
