fatigue driving alarm device in the eyes flicker detection method

摘要

check out the video signal from the video on the left and right to move the chart, histogram of height change with the flicker in order to find out the image detection means, the image signal is to be ubd84uc11dud558uc5ec the driver's eye position detection, the detection is the hypothetical video graphics set the stage, the stage of the graphics is the imaginary image of the left and right to move the eyes wide open when the video image is the maximum as the position detection of the phase and phase air detection in virtual video image is to be located in the most dynamic, with the changes of the height of the histogram changing rate for a period of time, the flicker detection, the detection reference value in order to set the stage andthe set value of the standard and the dynamic changes of the virtual image according to the image size and image size of the image is compared with the standard value or more is judged, were carried out to determine the size of the graph, the image and the standard value if the judged useless. to judge from the camera or get in on an image signal, the detection of the position of the virtual image is to the left of the chart. according to the dynamic changes of the rate of change of the image is the image of for the detection of flicker, the accuracy and reliability of the decision not to provide.
