Driver calling detection method and system based on computer vision technology

Abstract

The invention discloses a driver calling detection method and system based on a computer vision technology. The driver calling 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, and calling and operating a calling detection module to detect a calling posture, wherein the calling detection module comprises a plurality of calling detection sub-modules; and if any one of the calling detection sub-modules detects a calling behavior, storing the corresponding calling position, and stoprunning other calling detection modules. According to the driver calling detection method, the calling detection algorithm is faster in speed, lower in hardware requirement, stronger in algorithm expandability and lower in false alarm rate while the accuracy, robustness and the like are not reduced, and the whole equipment is smaller in size, low in hardware cost and controllable, and is easy tobe widely popularized as a consumer electronic product.

Description

technical field [0001] The invention relates to the technical field of dangerous driving detection of a vehicle safety system, in particular to a method and system for detecting a driver's phone call 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, playing with mobile phones while driving is one of the biggest accident-inducing causes, but there are currently no good preventive measures for playing with mobile phones while driving. [0003] Although there are some fatigue driving devices on the market that can detect driving and playing with mobile phones...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a method and system for detecting a driver's phone call based on computer vision technology, so as to at least solve the problems in the prior art that the detection algorithm is slow, the hardware requirements are high, and the applicability of the equipment is not strong.
