Example Embodiment

[0020] Example 1

[0021] Such as figure 1 , An intelligent control method for automobile driver fatigue driving. The fatigue driving intelligent control system recognizes the driver's actions and facial expressions based on the on-board near-infrared image sensor, which is characterized by including the following steps:

[0022] S1. Set several key points on the driver’s face, torso and limbs for marking;

[0023] S2. Track all key points through the vehicle-mounted near-infrared image sensor, train a model for action recognition through simulation detection and deep two-way LSTM neural network, and set dangerous actions based on the model for action recognition; in this embodiment, all The dangerous actions in step S2 include smoking, making a phone call, dozing off, yawning, opening and closing eyes intermittently, and other actions and states that may interfere with the driver's attention;

[0024] S3. Confirm the driver's identity through face recognition and store it as the cur...

Abstract

The invention relates to the field of vehicle safe driving, in particular to an intelligent control method for fatigue driving. The intelligent control method for vehicle driver fatigue driving comprises the steps that a plurality of key points are set on a driver face, a trunk, and arms and legs for being marked; all the key points are traced through a vehicle-mounted near-infrared image sensor,an action recognition model is trained out through simulation detecting and deep bidirectional LSTM neural network, and a dangerous action is defined based on the action identification model; and thecurrent driver is identified, matching is conducted in the vehicle running process, and if the dangerous action is matched out, an alertor begins to alarm and the driver is reminded of safe driving orresting. According to the intelligent control method for fatigue driving, after setting the key points on the whole body and the face, the model of the key points is established, subsequent judgmenterrors caused by vibrating back and forth of a vehicle in the running process is avoided, then dangerous actions at all levels are matched out through the action identification model, dangerous accidents are avoided, protection for safe travelling of the driver is provided, and loss of life and property is reduced.

Description

technical field [0001] The invention relates to the field of safe driving of vehicles, in particular to an intelligent control method for fatigue driving. Background technique [0002] Driver Fatigue Monitor System (Driver Fatigue Monitor System) is a driver fatigue monitoring and early warning product based on the driver's physiological response characteristics. At present, only the DD850 launched by Attention Technologies of the United States and the AntiSleep system launched by SmartEye of Sweden have been commercialized in the world. , Mercedes-Benz, Volvo's high-end car series, and the 13th-generation Crown sold by Toyota in Japan are also equipped with a drowsiness alarm system as standard. [0003] In addition, the fatigue monitoring system equipped with some cars is called "fatigue recognition system". judge. The driver's reduced frequency of steering operations, accompanied by light but jerky steering movements to maintain the direction of travel, is a typical sig...
