CTOnews.com November 28 news, according to the release of Tianma Microelectronics, Tianma design team combined the DMS system with the vehicle display screen, giving birth to a large-size vehicle intelligent display screen integrated with DMS function.

According to reports, in the aspect of intelligent and safe driving, DMS (driver Monitoring system) can monitor the driving behavior of drivers in real time, and make corresponding warnings, such as fatigue monitoring, distraction monitoring, dangerous driving monitoring and so on. Its working principle is to monitor the driver's head, eyes, face, hands and other details through the driver-oriented infrared camera, track its movement trajectory, identify and judge the collected data through the AI algorithm, and finally get the evaluation results and make warnings on the interactive platform (such as screen promotion, sound hints, seat belt tightening, etc.).

At present, DMS cameras on the market are installed separately in front of the center console or dashboard, or integrated on the steering wheel. This can detect the driver's facial information at the best angle, but for the whole vehicle, the addition of these cameras increases the complexity of the electronic system in the cockpit, leading to a certain increase in the cost of building the car. At the same time, the abrupt camera design also destroys the aesthetics of cockpit design and brings users a "sense of aggression" when exposed to the camera.

Tianma large-size high-definition intelligent DMS vehicle display screen, using the built-in SOC chip equipped with Tianma original algorithm, can not only recognize the driver's face and track the trajectory of eye movement, but also identify the driver's behavior through deep learning, such as "close your eyes", "yawn", "abnormal head position", "phone call", "smoking", "not in the monitoring area" and other six behaviors that affect driving safety. And the corresponding red warning message is displayed on the screen to ensure driving safety.

Tianma DMS vehicle intelligent display screen through the built-in 940nm near-infrared camera to achieve information collection. Different from conventional cameras, near-infrared cameras can actively emit infrared light when shooting, and then use imaging elements to receive infrared light reflected from the surrounding environment, so as to form an image. This can effectively avoid the adverse effects caused by lack of lighting, and accurate visual recognition can be carried out even in cloudy days or even under weak lighting conditions at night, including users wearing sunglasses.

CTOnews.com learned that this screen can also be used with Tianma's independently developed 3D gesture algorithm to achieve specific functions through the system's gesture recognition.
