Detection method and device, vehicle and storage medium

By installing detection modules and cameras in vehicles, combined with recognition models and breathalyzers, the probability of a driver having consumed alcohol can be accurately detected. This solves the problems of blind spots and low efficiency in existing drunk driving checks, and improves the comprehensiveness and safety of the detection.

AI Technical Summary

Technical Problem

In the current technology, it is difficult to detect drunk driving and driving under the influence of alcohol in a comprehensive and timely manner. It is impossible to detect all vehicles in real time, resulting in low inspection efficiency and blind spots and time lags.

Method used

By installing a first detection module and camera in the vehicle, video data of the air inside the vehicle and the driver are collected. The recognition model identifies the characteristics of the driver's actions and facial expressions. Combined with a breathalyzer to detect the alcohol concentration, the system can perform a graded test on the probability that the driver has been drinking and lock the vehicle.

Benefits of technology

It improves the accuracy and comprehensiveness of detecting drunk driving behavior, reduces the probability of drunk driving, ensures driving safety, avoids misjudgment, and takes into account the normal use needs of vehicles.

Abstract

The invention relates to a detection method and device, a vehicle and a storage medium, the detection method is used for the vehicle, the vehicle comprises a first detection module, an air blowing type alcohol detector and a camera, and the method comprises the steps that air in the vehicle is collected through the first detection module to detect whether the air in the vehicle contains alcohol or not; when the air in the vehicle contains alcohol, first video data of a first driver of the vehicle are collected through a camera, and the first video data comprise action features and expression features of the first driver; sending the action features and the expression features to a first recognition model to determine the drunk probability of the first driver; when the drinking probability is larger than a first preset value, the alcohol concentration of gas exhaled by the first driver is detected through a blowing type alcohol detector; when the alcohol concentration is larger than or equal to the second preset value, the vehicle is controlled to be locked, and an alarm is given out, the probability of drunk driving behaviors is reduced, and the inspection efficiency of the drunk driving behaviors is improved.
