In view of the problems such as low efficiency and large error in checking the dimensional deviation of ship finished pipe with the traditional measuring tools, an automatic measurement system for dimensional deviation of ship finished pipe based on multi-camera photogrammetry system is designed. The system is composed of close-range industrial photogrammetry dual-camera system, barcode scanning gun software integration system, real-time digital analysis software, and coding positioning technology equipment. It can realize the real-time online detection of different kinds of finished pipes and issue the detection results report. The system can improve the detection precision and efficiency of ship finished pipe.
