摘要： A distracted-driving monitoring method, system and an electronic device are provided. The distracted-driving monitoring method includes: acquiring an image of a driver; detecting a target object in the image to obtain a detection result; obtaining a determination result of a driving behavior according to the detection result; and sending an alarm signal when the determination result indicates that a distracted-driving behavior occurs. Through at least some embodiments of the present disclosure, the distracted-driving behavior of the driver can be monitored in real time and alarmed, thus urging the driver to concentrate in driving, to ensure safe driving and avoid traffic accidents. In addition, the specific type of the distracted-driving behavior can also be determined and different alarm signals can be given, which can be used as a basis for law enforcement or for data collection, data analysis, and further manual confirmation; thereby solving the problem of traffic accidents caused by not monitoring the distracted-driving behavior of the driver during driving.
