Abstract

The invention discloses an emotion recognition method and device when a user drives a vehicle, a storage medium and a terminal. The method comprises the steps of obtaining a facial expression in real time, performing data processing on the facial expression to extract facial feature data, and obtaining a facial information emotion state based on the facial feature data and a facial expression database; obtaining voice materials in real time, performing data processing on the voice materials to extract voice feature data, and obtaining a voice information emotional state based on the voice feature data and the voice expression database; detecting the heart rate and comparing the heart rate with a preset heart rate threshold value to obtain a heart rate information emotional state; and based on the facial information emotional state, the voice information emotional state and the heart rate information emotional state, judging the emotional state when the user drives the vehicle. According to the method, the judgment parameters of driver emotional state judgment are expanded, the emotional state judgment accuracy is improved, and car accidents caused by subjective factors such as poor emotional states in the driving process of a user are more effectively reduced.

Description

Technical field[0001]The present invention relates to the field of vehicle driving conditions, and in particular, to a user driving vehicle, a mood, storage medium, and a terminal.Background technique[0002]With the improvement of living standards, the car has gradually become part of our lives. The increasing increase in the car has increased the issue of road traffic safety. In order to strengthen traffic safety, coupled with the development of communication technology, the vehicle safety driving reminder system came into being.[0003]The existing vehicle safety driving reminder system is mainly used in the car navigation system. It is mainly based on the safety reminder of the corresponding vehicle speed according to the current driving section of the vehicle, and does not detect and remind the driver's driving state, so it is likely to be fatigue driving. Or driving in an emotional excitement, thereby causing a car accident. In order to further supervise the driver's driving state...
