Embodiment Construction

[0046] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0047] like figure 1 Shown, a kind of real-time monitoring early warning method of the rail train driver state based on Kinect comprises the following steps:

[0048] Step 1: Utilize the Kinect sensor array arranged in front of the cab to collect the working status information of the rail train driver;

[0049] The track train driver's working status information includes track train driver color image data, depth data, bone image data and voice data;

[0050] Step 2: Carry out data processing to the rail train driver's working state information;

[0051] Carry out the heart rate detection of the rail train driver on the collected color image of the rail train driver;

[0052] Extract facial features from the collected color images of rail train drivers, use the Euler video amplification method, read the RGB representative pixels of each frame of facial feat...

Abstract

The invention discloses a Kinect-based real-time monitoring and early warning method and system for the status of rail train drivers. The method cleverly arranges the Kinect sensor, comprehensively utilizes various detection functions of the Kinect sensor, and uses only one Kinect sensor. Realized multiple functions of train start detection, driver heart rate monitoring, fatigue monitoring, and misjudgment monitoring, using color image data, depth data, bone image data and voice data acquired by the Kinect sensor for data processing; fusion and use of various detection data , combined with the method of fusion of rail train driver voice information, driver gesture information, and train command signal information, directly prevent the driver from misjudging the signal and command from the technical solution; the system is simple in structure, easy to operate, and greatly reduces The cost of the monitoring and early warning system is reduced, and it has accurate monitoring and early warning effects.

Description

technical field [0001] The invention belongs to the field of rail traffic control, in particular to a Kinect-based real-time monitoring and early warning method and system for the state of rail train drivers. Background technique [0002] During the train running, the physiological state of the train driver has a great influence on the safe operation of the train. The physiological state of train drivers mainly includes physiological health state and fatigue state. According to the Statistical Yearbook of Traffic Accidents, about 15-20% of railway traffic accidents are related to driver fatigue. Fatigue driving seriously affects the alertness, adaptability and safe driving ability of train drivers. In order to prevent the safety hazards of rail trains caused by fatigue driving, there is a button under the driver's foot in the cab, which requires the driver to step on it once within a certain period of time. Once the specified time is exceeded, the button will issue a warnin...
