Elevator speed governor action speed verification method based on visual algorithm

The invention provides an elevator speed governor action speed verification method based on a visual algorithm, which comprises the following steps of: S1, positioning three tracking points on a speed governor, namely a point A on the outer ring of the speed governor, a point B on the circle center of the speed governor and a point C between the speed governor and the center of the speed governor; s2, the target speed governor is accelerated through the automatic frequency conversion uniform acceleration electric hand drill, and the whole process of acceleration-electric switch action-mechanical action is recorded; s3, importing an image shot by the camera into a computer; s4, calibrating the set tracking points A, B and C in the image; s5, measuring and calculating instantaneous images, captured by the camera, of the electric action and the mechanical action of the speed limiter through a visual algorithm tool; s6, exporting the distance data of the points A-B and the linear velocity data of the point A, and
