Embodiment 1

[0049] Such as figure 1 As shown, the present invention discloses a method for detecting a driver's dangerous driving behavior, and the method includes:

[0050] Step 1. When the driver holds both sides of the steering wheel with both hands and maintains a standard posture, use the Kinect camera to collect the skeleton posture of the driver at this time, and establish a standard posture model;

[0051] The invention proposes a method for extracting a driver's posture by using a Kinect depth camera and analyzing whether the driver has dangerous driving behavior. This method does not require the driver to wear various measurement sensors, nor does it need to install a large number of sensors on the vehicle, and truly realizes non-contact driver behavior detection without any interference with the driver's normal driving, and can be done during the day and at night Detect driver behavior in low-light conditions.

[0052] The Kinect somatosensory camera of Microsoft Company has ...

Embodiment 2

[0150] The driver's dangerous driving behavior detection method provided by the present invention is tested and verified, and the test object is a bus driver, specifically including:

[0151] Step 1, deployment experiment scene, Kinect equipment is installed in the bus cab;

[0152] Step II, driver posture calibration, let the driver take a standard driver posture and hold it for 3 seconds, at this time, the system records the driver's skeleton posture under the standard posture, and keeps this posture in the structure BodyPoints.

[0153] Step III, detecting whether the driver has dangerous driving behavior, including:

[0154] (1) Detect whether the driver's hand leaves the steering wheel

[0155] Whether the method of the present invention can be detected accurately in real time is tested by continuously increasing the number and frequency of the driver's hands leaving the steering wheel.

[0156] Table 1 Test with driver's hands off the steering wheel

Abstract

The invention discloses a method for detecting a dangerous driving behavior of a driver, which can obtain various parameters of a steering wheel, realizes adaptive detection of steering wheel parameters of various vehicles, and does not need any manual parameter input. Vehicle steering wheel data obtained from depth data and steering wheel modeling can be used to detect driving behavior without any sensor and data interface, which greatly facilitates the detection of driving behavior; Driving behavior detection can be started quickly, and the detection condition is not affected by ambient light, which greatly improves the feasibility of vision-based driver risk behavior detection.

Description

technical field [0001] The invention relates to a behavior detection method, in particular to a driver's dangerous driving behavior detection method. Background technique [0002] In the cutting-edge research at home and abroad, the detection and analysis of the driver's fatigue state and driving behavior are mainly carried out. It is the most intuitive and effective method to analyze the driver's behavior by analyzing the driver's mental state and behavior. research direction. The research is mainly divided into: the driving behavior detection based on the driver's physiological state, the driving behavior detection based on the vehicle's running state, and the detection of the driver's behavior through computer vision technology. [0003] At present, the more commonly used physiological states are: EEG (electroencephalogram signal), EGG (cardiogram signal), EMG (muscle electrical signal), but in order to measure these parameters, it is necessary for the driver to wear a s...
