Abstract A method to measure wall thickness of continuous casting ladle based on laser positioning and ranging is proposed. Firstly, positioning lasers are used to detect the spatial coordinates of the measured ladle. Secondly, the inner surface of the ladle is scanned by measuring laser driven by a rotary platform. According to the spatial coordinate transformation, the data of the measured points on the inner surface of the ladle are mapped to the wall thickness of the ladle. Finally, the thickness distribution of the inner wall of the ladle is obtained by comparing wall thickness with the standard initial data of the ladle. After test in the metallurgy filed, it shows that the method can measure the thickness of ladle wall accurately, the maximum measuring error is 5.2 mm, the minimal error is 2.6 mm, and the average error comes to 3.6 mm.
