Method for measuring lay length and unevenness of steel wire rope

The invention discloses a steel wire rope lay length and steel wire rope unevenness measuring method, which is specifically implemented according to the following steps: step 1, carrying out image acquisition along the central axis direction of a steel wire rope by using a digital camera, and processing the acquired image; 2, positioning the edge of the processed digital image; step 3, carrying out data acquisition on the image positioned in the step 2; and 4, respectively calculating the lay length and the unevenness of the steel wire rope by using the data obtained in the step 3. The lay length and the unevenness of the steel wire rope in the production or use process can be automatically monitored on line to meet the precision requirement. 本发明公开了一种钢丝绳捻距和钢丝绳不平整度测量方法，具体按照以下步骤实施：步骤1、利用数码相机在沿着钢丝绳中心轴线方向上进行图像采集，并对采集的图像进行处理；步骤2、对处理后的数码图像边缘定位；步骤3、对步骤2定位后的图像进行数据采集；步骤4、利用步骤3得到的数据分别计算钢丝绳捻距和钢丝绳不平整度。实现了对钢丝绳在生产或使用过程中的捻距和不平整度进行满足精度要求的自动在线监测。
