Abstract

The invention provides a method for detecting physiological indexes of a driver, and belongs to the technical field of rPPG physiological index detection, the method can generate a first signal and a second signal, the first signal comprises a physiological signal and a noise signal, and the second signal reflects the change of the intensity of light along with time; the first signal and the second signal are input into a signal model, the signal model can remove a noise signal from the first signal according to the change of the illumination intensity reflected by the second signal, a physiological signal without noise is obtained, and then the physiological index of the driver is determined. The noise signal is introduced by the intensity change of the light, and when the light continuously changes, the signal model can effectively remove the noise signal, so that the method provided by the invention can improve the accuracy of the physiological indexes of the driver detected in the actual driving scene.

Description

technical field [0001] The application belongs to the technical field of rPPG detection of physiological indicators, and in particular relates to a method for detecting a driver's physiological indicators and establishing a model. Background technique [0002] Fatigue driving and distracted driving are the main causes of traffic accidents. Detecting the driving state of the driver and giving advance warning to abnormal driving can effectively avoid traffic accidents. Physiological indicators can effectively reflect the driver's driving state, such as the driver's fatigue driving, concentrated driving, psychological tension, emotional changes and other states will be reflected in the heart rate. Physiological indicators can be obtained through non-contact measurement methods. [0003] Existing non-contact measurement methods usually calculate physiological indicators under the premise of stable light, and are only suitable for scenes with small light changes. In the actual...
