A dynamic calibration method for a driving monitoring system

Abstract

A dynamic calibration method for a driving monitoring system is implemented by an in-vehicle driving monitoring device, generates standard image information according to a feature standard deviation generated from a facial image of a driver and a preset standard deviation threshold, generates calibration evaluation image information according to the current driving image features of the driver and the standard image information and a preset triggering event setting, and then calculates a driving posture movement amount by using the standard image information and the calibration evaluation image information. Finally, the driving posture movement result is generated by using the driving posture movement amount and the posture movement amount threshold, to instruct the driving posture movement amount is greater than a posture movement amount threshold to avoid a continuous trigger alert due to a driving posture change.
