Abstract

The invention provides a driving behavior analysis method and system. The method comprises the following steps of receiving a real-time road condition image sent by vehicle-mounted equipment, using aCNN model to identify the real-time road condition image, and acquiring an object type in the real-time road condition image; and using an LSTM model to carry out semantic prediction on the object type and outputting corresponding prompt information. In the invention, semantic identification can be performed on the road condition image sent by the vehicle-mounted equipment so as to prompt a driverto drive cautiously.

Description

technical field [0001] The invention relates to the technical field of deep learning networks, in particular to a driving behavior analysis method and system. Background technique [0002] More and more people own cars in modern society. While cars bring convenience to people's travel, traffic accidents also occur from time to time, often resulting in serious loss of life and property. The driver's driving behavior directly affects driving safety. Good driving behavior can not only reduce the incidence of traffic accidents, but also reduce driving risks. Accurately evaluating the driver's driving behavior has become a very important topic. The driver's driving behavior is affected by many factors, such as the number of vehicles and pedestrians on the road, the situation of deviation from the lane line, weather conditions, vehicle speed and distance between vehicles, etc. Accurately capturing and extracting these factors that affect driving behavior is the key to evaluating d...
