Abstract

The invention discloses a dangerous driving behavior detection method and a camera. The method of the present invention includes: acquiring the infrared image and the depth image of the driver, and the pixels between the infrared image and the depth image have a one-to-one correspondence; using the face recognition algorithm to identify the infrared image, and obtaining the facial feature points of the driver ; Obtain the behavior detection area of ​​the driver in the infrared image according to the facial feature points; According to the gray value, depth image and corresponding relationship of the pixels in the behavior detection area, identify whether there is a preset marker in the behavior detection area to obtain the driver's state Behavior; Wherein, when the preset marker is recognized, the obtained state behavior corresponds to dangerous driving behavior, and when the preset marker is not recognized, the obtained state behavior corresponds to standard driving behavior. The invention can well suppress the false alarms brought in by the front and back background interference or the reflection on the face, and effectively improve the detection accuracy.

Description

Technical field [0001] The present invention relates to the field of machine learning technology, particularly to a method for detecting dangerous driving behavior and the camera. Background technique [0002] In recent years, more and more safe driving is discussed as a public topic, especially in driving the process of calling and smoking behavior. Phone will distract the driver strain diminished capacity; the driver will cause a decline in smoking cabin air quality, cause harm to the health of passengers. These dangerous driving behavior caused by road hazards also brought pain to many families. Accurate and efficient detection driving behavior of the driver in driving the process, and when to alert a driver reduce the risk of irregularities lead to a means of driving effective. [0003] Art, usually a camera to monitor the driver's behavior, with the development of machine vision technology, using image analysis techniques to monitor driving behavior gradually become a new me...
