Lend me a pair of "smart eyes" and come to Fuzhou to see the "chemical reaction" of smart cameras and multiple application scenarios!

[51CTO.com original article] On March 21, Huawei China Eco Partner Conference 2019 was grandly held at the Straits International Convention and Exhibition Center in Fuzhou. In order to let the 20,000 guests at the conference truly experience the intelligent applications, Huawei and more than 20 world-class partners built a "smart island" according to the standards of a real smart park. 208 cameras, 13 gates, and more than 1,000 sensors were deployed on the island. Huawei connected 33 systems to achieve a hybrid main network on and off the cloud, and seamlessly integrated services and data.

Walking around the exhibition halls, pavilions, and smart islands, the application of cameras is what I am most interested in. In my observation, almost 80% of smart scenes are inseparable from cameras. Cameras are like the nerve endings of smart scenes, and only through their tentacles can we know the external environment clearly.

Many people may scoff at this, thinking that it is just taking a photo and uploading a video, what is there to pay attention to? Not at all, taking photos and uploading videos are just basic functions of cameras, but how can wide-scene lenses accurately identify abnormal behaviors? How to capture high-speed cars? How to capture lens details in backlit scenes at night? Which pictures of the same scene are normal and which pictures need warnings? If you want to know the answers to these questions, why not follow the author to take a look at the smart applications of Huawei's smart camera family!

The author learned that Huawei's smart cameras currently have five series, namely Xingchen, Xingdun, Xingxiang, Xingchi, and Xingtu, commonly known as the "Five-Star Series" (people with trypophobia please stay away from this picture). Each series corresponds to different application scenarios. For example, "Xingtu" can achieve situational awareness, "Xingxiang" is good at accurate face recognition in high-density scenes, "Xingchi" is particularly good at the license plate color, brand and model of vehicles, "Xingdun" can accurately capture the information of vehicles at a speed of 200 kilometers per hour on the highway, and "Xingtu" is used for full structured non-human images, mainly targeting the high-end application market.

So the question is, how do these cameras combine with smart applications to create a "chemical reaction"? Don't worry, the author has the spirit of "breaking the casserole to get to the bottom of it", and of course he will not miss any wonderful applications!

This picture is a comparison of the pictures taken by Huawei's traditional camera and smart camera. The traditional camera on the right can only capture a sidewalk, while the camera on the right is three times wider. In addition to the pedestrian passage, it can also capture the pictures of the two lanes on the right. If you think that smart cameras are as simple as taking more pictures, you are wrong. From the picture at the bottom of the screen, you can see that the camera can separate the pictures of people and cars. People's age, gender, and expressions can be analyzed, and the model, license plate, color, and brand of the car can also be seen at a glance. As for what kind of black technology it uses, I will keep it a secret for now, so please look forward to Huawei's official release! From a practical point of view, if the traffic police or criminal police want to find someone or a car, isn't it much more convenient?

This picture was taken at night without street lights. In the traditional camera on the right, the light is very dim without street lights. When cars and pedestrians pass by the camera, the car lights are too bright to capture the license plate, and the pedestrians' faces are not clearly captured due to the dim light. On the left is the picture taken by Huawei's smart camera. Huawei uses intelligent recognition to perform zoned exposure for cars and pedestrians in the picture. On the one hand, it reduces the brightness of the car lights to capture clear license plates, and on the other hand, it increases the exposure of pedestrians' faces to ensure that their facial features are clear and recognizable.

After listening to the introduction of the person in charge, the first reaction of the author is that the community park is particularly suitable for installing this smart camera. With it, security protection is a qualitative leap!

Many guests may not have paid attention to the camera on the roof of the venue. This camera is called a 4K super starlight situation control camera. With 8 million pixels, it can realize ultra-long-distance starlight low-light AI intelligent monitoring, can capture faces at a distance of 150 meters, and perform face recognition at a distance of 500 meters. What does this set of data mean? Please see the figure below:

This is the picture captured by the 4K high-definition dome camera. You can see that people and cars can be captured very clearly near the circular plaza in the distance. This is far more than the farthest distance it can capture! Just imagine, in a square, a rally, or a large-scale performance or concert, with it, the staff in the monitoring room can sit in the room and keep an eye on all directions, and no details can escape its eyes.

The picture above is the legendary ultra-high-speed snapshot that can be clearly captured even at a speed of 200 kilometers per hour. With it, the author advises all veteran drivers not to take chances. It is useless to speed up to 200 kilometers per hour. Whether you are making a phone call or wearing a seat belt can be seen clearly!

This picture shows the crowd density detection and high-density portrait capture I saw in the exhibition hall, which captured the real-time situation in the venue. It is understood that Huawei's smart camera can recognize 200 portraits in each frame, which is the best level in the industry. If this camera is installed in crowded places such as subways and stations, it can help subway operators reduce a lot of security pressure.

When I saw this camera placed in a fish tank, I imagined a lot of scenarios, such as underwater monitoring, or the camera also serving as a water flow sensor... It turns out that I was overthinking. The person in charge of the booth told the reporter that the camera was placed in a fish tank to prove that the camera is very waterproof and has no problem with quality in areas with long and humid rainy seasons. Well, my imagination was a bit too big.

Do you think this first picture is to tell you how much black technology is inside Huawei's smart camera? No, no, I'm just kidding. This picture is just to show how good the heat dissipation performance of Huawei's camera is. Please pay attention to the camera's shell, which is double-layered. The double-layer structure of the shell forms a chimney-style heat dissipation duct to help accelerate the discharge of heat. In addition, there are two micro fans built into the ball camera to form an internal vortex airflow to avoid local overheating and facilitate heat dissipation!

The application scenarios that I introduced above are carefully selected and closely related to people's travel, safety, and life. In fact, there are many more application scenarios for smart cameras. I am sorry that I cannot describe them one by one due to limited space. If you are not satisfied with my "throwing a brick to attract jade", you may as well come to Fuzhou to see Huawei's "smart island" and see it for yourself!
