Abstract

The invention discloses a driver smoking detection method and system based on a computer vision technology. The driver smoking detection method comprises the steps: obtaining external image information from a camera, and carrying out the face detection in real time; when the human face is detected, selecting the maximum human face as the human face for subsequent analysis by comparing the sizes ofall detected human face areas; performing block division on the obtained maximum face area to obtain a face mouth block; calling and operating a plurality of smoking detection modules to detect the mouth block; and if any smoking detection module detects the smoking behavior, storing the corresponding smoking position while other smoking detection modules stop running. In the driver smoking detection method, the smoking detection algorithm is higher in speed, lower in hardware requirement, higher in algorithm expandability and lower in false alarm rate; and the accuracy, robustness and the like cannot be reduced, and the whole equipment is smaller in size, low in hardware cost and controllable and can be easily and widely popularized as a consumer electronic product.

Description

technical field [0001] The invention relates to the technical field of dangerous driving detection of vehicle safety systems, in particular to a method and system for detecting driver smoking based on computer vision technology. Background technique [0002] At present, there are more and more private cars, and the traffic is more and more developed, and the frequency of people traveling by car has greatly increased compared with before. Although the number of times of driving has increased, people's awareness of safety precautions has not increased accordingly. How to ensure driving safety in this case is a very important issue. Among all driving accidents, smoking while driving is one of the biggest accident-inducing causes, but currently there are no good preventive measures for smoking while driving. [0003] With the introduction of active safety driving regulations by the domestic government and the outbreak of the active safety market, some devices to prevent fatigu...
