The Method of Measuring the Length of Straight Seam Steel Pipe
According to the different process requirements of different customers, there are various methods for the length measurement system of straight seam steel pipe , mainly are the following types: 1. Raster ruler for length measurement Measuring the length with a raster ruler is to install two raster rulers of fixed length on the outside of both ends of the straight seam steel pipe. The raster ruler is driven by the pole columns close to both ends of the steel pipe, and the length of the straight seam steel pipe is measured by the interference phenomenon of light. The length measurement accuracy with a raster ruler is very high. However, the raster ruler is expensive and difficult to maintain, so it is very sensitive to the influence of dust and on-site vibration. 2. Camera for length measurement Measuring the length with a camera is to realize the measurement of the steel pipe length through image processing. The principle is to install a series of photoelectric switches at equal d...
