Knob switch state detection method and device, equipment and storage medium

The invention relates to an image processing technology, and discloses a knob switch state detection method, which comprises the following steps: acquiring an inspection switch image, and judging whether the quality of the inspection switch image meets a preset image quality standard or not; if not, filtering out the inspection switch image; if yes, detecting a switch coordinate frame in the inspection switch image by using a pre-constructed target detection model; positioning the position information of the knob switch according to the switch coordinate frame, and cutting the inspection switch image according to the position information to obtain a cut switch image; and performing target segmentation on the shear switch image by using a pre-trained segmentation network, obtaining a switch state identification result based on a target segmentation result, and mapping the switch identification result to the inspection switch image to obtain the switch state of the knob switch. The invention further provides a
