Embodiment Construction

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

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

[0048] Step 1: Use the Kinect sensor array arranged in front of the cab to collect the driver's working status information;

[0049] The driver's working state information includes the driver's color image data, depth data, bone image data and voice data;

[0050] Step 2: Perform data processing on the driver's working status information;

[0051] Carry out the driver's heart rate detection on the collected driver's color image;

[0052] Extract facial features from the collected color image of the driver, use the Euler video amplification method to read the RGB representative pixels of each frame of facial feature images, use a band-pass filter to filter the RGB representative pixels, and ...

Abstract

The invention discloses a method and a system for monitoring and early warning rail train driver state in real time based on Kinect. The method can only use one Kinect sensor to realize multiple functions such as train start detection, monitoring of driver heart rate, fatigue monitoring and misjudgment monitoring by ingeniously setting the Kinect sensor and comprehensively utilizing all detection functions of the Kinect sensor, and can use the Kinect sensor to perform data processing on acquired color image data, depth image data, bone image data and voice data; according to the method, all detection data is combined for use, and the fusion of rail train driver voice information, driver gesture information and train command signal information characteristics are combined, so that the phenomenon that a driver misreads or misjudges a signal or command can be directly avoided from the view of technical scheme; the system is simple in structure and convenient to operate, greatly lowers the cost of a monitoring and early warning system and has effects of accurately monitoring and early warning.

Description

technical field [0001] The invention belongs to the field of rail traffic control, in particular to a Kinect-based method and system for real-time monitoring and early warning of rail train driver status. 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 warning to...
