Research on detection technology for body of large shield machine
In view of complex operation and low efficiency of detection of high-precision large work piece,a kind of detection method combining measure technology was proposed.After analyzing the measuring features of the laser tracker and the industrial photogrammetry,the laser tracker was applied to establish largescale datum ruler to control the precision.In addition,the industrial photogrammetry was combined to detect and analyze the body roundness of the shield machine via layout of marking points,image acquisition and adjustment treatment,coordinate conversion.The results showed the technology was simple and efficient,able to satisfy the measurement requirements and had become a new method of large-size measurement.
