Embodiment Construction

[0019] The present invention proposes a detection method for the illegal behavior of the driver holding the phone while driving, the flow chart of which is as follows figure 1 shown, including the following steps:

[0020] (1) Gather the head image of the car driver, set a human face area queue, use the face detection algorithm to detect the human face from each frame of the head image collected, and judge the detection result. If the human face is detected, Then locate the rectangular human face area according to the detected human face, update the face area queue with the located rectangular human face area, and use the located rectangular human face area as the rectangular feature human face area; if no human face is detected, Then judge the face area queue, if the face area queue is empty, continue to detect the face, if the face area queue is not empty, use the average value of the rectangular face area in the face area queue as the rectangular feature face area ;

Abstract

The invention relates to a method for detecting the phone holding violation of a driver in driving, and belongs to the technical field of machine vision. The method comprises the following steps of: acquiring a head image of an automobile driver, detecting a face in the head image of the driver by utilizing a face detection algorithm, and positioning a rectangular face region according to the detected face; positioning a left rectangular ear region and a right rectangular ear region according to the rectangular face region, and extracting characteristic indexes from the left and right rectangular ear regions; inputting the characteristic indexes into a mode identification algorithm, identifying whether the driver holds a phone or not in the head image, and storing an identification resultinto a phone holding result queue; and performing logic judgment on the phone holding result queue, and giving an early warning to the driver according to a logic judgment result. The method is high in real-time performance and identification accuracy; and the left-hand and right-hand phone dialing and answering behaviors of the driver can be detected and early warned, so that traffic accidents caused by the phone dialing and answering in driving can be effectively reduced, and driving safety is further improved.

Description

technical field [0001] The invention relates to a method for detecting violations of the driver's hand-held phone while driving, more specifically, the invention is a method for real-time detection of the driver's hand-held phone violation by using image processing and pattern recognition algorithms, belonging to field of machine vision technology. Background technique [0002] During the driving process, the choice and judgment of the road conditions make the driver's attention highly concentrated. If he dials and answers the handheld phone at this time, it will inevitably distract part of his attention, reduce his ability to perceive the driving environment, and correspondingly weaken his awareness of the road conditions. Judgment, the reaction speed is reduced, and it is very easy to cause traffic accidents. During normal driving, the driver controls the steering wheel with both hands. When making or receiving a hand-held phone, the driver uses one hand to control the st...
