State recognition method and device for driver to make and receive calls while driving

Abstract

The present application provides a state recognition method and device for a driver to make and receive calls while driving. The method includes: locating the window of the target vehicle in the monitoring image; Driver detection candidate region; Utilize direction gradient histogram and support vector machine to detect described driver detection candidate region, obtain the head shoulder area of ​​described driver; Input the first layer CNN network and the first layer CNN network and the first layer of described head shoulder region successively by described head shoulder region Two-layer CNN network, described first-layer CNN network carries out initial screening to described head and shoulder area, obtains the driver's head-shoulder area of ​​suspected answering and calling, described second-layer CNN network is to described first-layer CNN network The output results are further screened to obtain the status of the driver answering the phone. The application can eliminate false pick-ups of non-real phone calls in complex scenes, improve recognition accuracy, and have good scene adaptability and robustness.

Description

Technical field [0001] The present application relates to video monitoring, and in particular, to a driving driver and receive calls state recognition method and apparatus. Background technique [0002] If the driver in driving the process and receive calls, it will greatly increase the incidence of traffic accidents, therefore the need for truck drivers receive calls for effective recognition of the state, as an important evidence of whether its violation. [0003] With the development of image processing, computer vision technology, depth of learning technology and embedded technology, how the vehicle (including occupants) illegal automatic identification and forensics has become a hot topic in the current intelligent transportation. [0004] The prior art provides a method of identifying the driver's cell phone behavior method (CN105868690A), the video stream is first collected in the cockpit, through the face of the person positioning element model face region, the face follo...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the present application provides a state recognition method and device for the driver to make and receive calls while driving, so as to solve the problem of low accuracy in state recognition of the driver for making and receiving calls while driving in the prior art
