Abstract

The invention relates to the field of driver state monitoring, and discloses a driver state detection method, a driver state detection device, a vehicle-mounted terminal and a system. The driver statedetection method comprises the following steps that when a vehicle-mounted terminal detects that a driver is in a driving state, a current driver image is collected; The vehicle-mounted terminal carries out first type detection on the state of the driver based on the driver image and sends driving data including the face characteristics of the driver to the cloud end, so that the cloud end carries out second type detection different from the first type detection on the state of the driver; Wherein the face features are obtained based on the current driver image. The driver state can be detected by simultaneously utilizing the advantages that the vehicle-mounted terminal can quickly respond to the driver state and the cloud end can carry out high-performance calculation on the driver state, so that the timeliness and the accuracy of driver state detection are improved.

Description

technical field [0001] The invention relates to the field of driver state monitoring, in particular to a method for detecting the state of a driver, a device thereof, a vehicle-mounted terminal and a system. Background technique [0002] According to statistics, the number of deaths caused by traffic accidents in the world is 600,000 every year, and the direct economic loss is about 12.5 billion US dollars. Among these accidents, 57% of catastrophic accidents are related to fatigue driving. Therefore, driver state detection for fatigue driving is of great significance. [0003] In the process of detecting the driver's state, the driver's state can be detected by contact means such as detection of heartbeat and pulse, and the driver's state can also be analyzed and estimated by using the camera to detect the driver's facial macroscopic movement and local movement. status. Camera-based driver state detection has been widely used in driver state detection due to the advantage...
