Vehicle driving safety pre-warning method and system based on environmental monitoring

Abstract

The invention discloses a vehicle driving safety pre-warning method and system based on environmental monitoring. The method comprises the steps of obtaining the driving information of a vehicle in real time, further judging whether the vehicle is in an advancing state or a reversing state, if the vehicle is in the advancing state, directly executing an advancing pre-warning step, and if the vehicle is in the reversing state, directly executing a reversing pre-warning step; in the advancing pre-warning step, adopting a binocular camera mounted on the vehicle to collect real-time images around the vehicle, judging whether an obstacle exists, if the obstacle exists and the distance between the obstacle and the vehicle is within a safe distance, broadcasting the area of the obstacle and the distance between the obstacle and the vehicle; in the reversing pre-warning step, adopting the binocular camera mounted on the vehicle to collect real-time images on the two sides and the tail of the vehicle, judging whether the vehicle is reversed and enters a garbage, if so, broadcasting the distance between a berth line and the vehicle. The driving environment around the vehicle can be detected comprehensively, safety pre-warning can be realized in time, and the method can be widely applied to the safe driving field of the vehicle.

Description

technical field [0001] The invention relates to the field of safe driving of vehicles, in particular to a vehicle driving safety early warning method and system based on environment monitoring. Background technique [0002] With the rapid development of the national economy, the number of automobiles in our country has increased significantly, followed by various problems such as road congestion and frequent traffic accidents, which have brought huge losses to people's lives and property safety. Therefore, The safe driving of vehicles has become an extremely important issue. Among them, the monitoring of the surrounding environment and the measurement of the distance from the surrounding objects during the driving of the vehicle are very important and urgent. At present, vehicle systems such as buses and private cars are generally equipped with on-board camera systems, which can assist in monitoring the situation of people on board, or perform reversing monitoring, etc. Ho...

Problems solved by technology

However, most of this vehicle-mounted camera system is fixed at the rear of the vehicle and cannot be moved. It is mainly used to realize the real-time monitoring and viewing of invisible areas by the driver, so as to ensure the safety of passengers when the vehicle opens and closes the door and the safety of the vehicle when the driver reverses the car. , has great limitations, the viewing angle is small, and it needs to rely on the rearview mirror, so it cannot fully monitor the environment around the vehicle. Moreover, this system also requires the driver to observe and judge, and it is still based on the driver's artificial Participation and judgment, in the case of complex driving situations or when the driver is not concentrating, will not bring better results to the safe driving of the vehicle

Moreover, the current technology cannot automatically monitor the environment around the vehicle and give timely warnings when obstacles and other situations occur during the driving process of the vehicle.
