In the production and manufacturing process of the angle steel of the power transmission tower, measuring tools such as calipers, box rulers and the like are generally adopted, and the inspection is carried out in a manual spot inspection mode one by one and one by one.
With the development of detection technology, aiming at the problems existing in the detection process of the angle steel, quality detection devices based on the principle of angle steel processing characteristics of vision and ultrasonic detection appear in succession in recent two years, measurement of the angle steel processing characteristics is realized based on machine vision, ultrasonic sensing and corresponding measurement methods, and an attempt is made to replace manual detection methods.
