Driver abnormal posture detection method

Abstract

The invention discloses a driver abnormal posture detection method and belongs to the field of automobile advanced auxiliary driving systems. The driver abnormal posture detection method is used for preventing traffic accidents caused by abnormal postures of a driver in the driving process and comprises the steps that when the behavior postures of the driver are monitored, whether the driver is inthe abnormal driving posture or not is distinguished through an abnormal posture judgment criterion, and then whether a behavior classifier is started or not is determined according to the judgment result, wherein the abnormal driving posture comprises actions of making a call, drinking water, smoking, playing a mobile phone and leaving the steering wheel by one hand or two hands. Compared with amethod for monitoring driver behaviors by globally using a behavior classifier, the driver abnormal posture detection method has the advantage that more limited computing resources can be saved on the premise of ensuring the same detection precision.

Description

technical field [0001] The invention belongs to the technical field of advanced automobile driving assistance systems, and in particular relates to a method for detecting abnormal posture of a driver. Background technique [0002] With the rapid development of computer vision technology, many driver monitoring systems with superior performance have emerged in the automotive field. These driver monitoring systems can monitor all kinds of abnormal driving behaviors of drivers in the driving process and take real-time warnings to prevent traffic accidents. However, in real driving conditions, the driver will maintain the correct driving posture for a long time, and will only be in an abnormal posture for a short time. If the global classification detection is carried out throughout the entire driving section, it will undoubtedly occupy more limited computing resources and affect the normal operation of other on-board systems.

Problems solved by technology

[0003] The problem to be solved by the present invention is to invent a method for detecting abnormal posture of a driver that can maintain high detection accuracy and save computing resources in view of the contradiction between high precision and high computing resource occupation in the existing driver monitoring system

That is, on the basis of the original global monitoring method, the abnormal driving posture judgment criterion is added as the basis for whether to enable the behavior classifier to solve the problem of excessive computing resources occupied by the global monitoring method; combined with the driving behavior classifier trained by the deep neural network to ensure higher detection accuracy
