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 drawing a curve graph of the distance and the velocity; according to the invention, the speed governor can be verified safely and quickly.

    本发明提供了一种基于视觉算法的电梯限速器动作速度校验方法,所述方法包括以下步骤:步骤S1、在限速器上定位三个跟踪点,分别是限速器外圈上一点A、限速器圆心上一点B和限速器和限速器中心之间一点C;步骤S2、通过自动变频匀加速手电钻对目标限速器进行加速,记录加速‑电气开关动作‑机械动作全过程;步骤S3、将摄像机所拍摄的图像导入计算机内;步骤S4、在图像内通过对所设置的跟踪点A点、B点和C点进行标定;步骤S5、通过视觉算法工具对摄像机捕捉到的限速器电气动作和机械动作瞬时图像进行测算;步骤S6、将A‑B点距离和A点线速度数据导出,绘制距离和速度的曲线图;本发明能够对限速器进行校验且安全快捷。
