Abstract

The invention provides a driving early warning method and device based on multi-modal data, a medium and a program product, and relates to the technical field of driving early warning. According to the method, multiple groups of driving data are acquired through acquisition, and the driving data comprise front vehicle reference data, driving state data of a driver of the vehicle and driving behavior data of the vehicle; according to the multiple groups of driving data and a preset recall strategy, a corresponding alarm mode is determined; and an alarm is given according to determined alarm mode. By applying the embodiment of the invention, the alarm is given based on the reference data of the front vehicle, the driving state data of the driver of the vehicle and the driving behavior data of the vehicle, so that comprehensive consideration is realized during alarming, the accuracy of alarming is improved, the driver is warned in time, and the safety coefficient of the driver is improved.

Description

technical field [0001] The present application relates to the technical field of driving warning, in particular to a driving warning method, device, medium and program product based on multimodal data. Background technique [0002] Advanced Driving Assistance System (Advanced Driving Assistance System, ADAS) is to use various sensors (millimeter wave radar, laser radar, single / binocular camera and satellite navigation) installed on the car to sense the Surrounding environment, collect data, carry out identification, detection and tracking of static and dynamic objects, and combine with navigation map data to carry out systematic calculation and analysis, so as to give early warning to drivers. [0003] In the existing driving warning system based on the advanced driving assistance system, the warning is generally performed by calculating the distance between the own vehicle and the vehicle in front. [0004] It can be seen that the existing early warning strategy is relativ...
