Real-time identification method for on and off states of indicating lamp

The invention provides a real-time identification method for on and off states of an indicating lamp. The method comprises the following steps: step one, carrying out identification area demarcation on the indicating lamp; 2, determining a preset value of the state of the indicator lamp; 3, extracting an image corresponding to the identification area of the indicator light; 4, adjusting the brightness value of the image corresponding to the recognition area of each indicator light; and step 5, judging the state of the indicator lamp in real time. According to the method, the influence of the size and shape of the indicator light on the recognition result can be well eliminated in a mode of defining the recognition area; according to the method, the brightness value of the area where the indicator lamp is located is adjusted according to the brightness value of the auxiliary recognition area obtained when the preset value of the indicator lamp state is determined, then the on-off stateof the indicator lamp is
