Problems solved by technology

However, the disadvantage of this measurement method is that it is necessary to repeatedly adjust the position of the rope exit during measurement to ensure that the pull rope is in a straight line. This operation process is cumbersome.
Since there is a certain gap between the pull rope and the pull rope head, it is ensured that the pull rope can be pulled out smoothly, resulting in a slight deviation in the position of the center axis of the pull rope head as the center of the ball, resulting in a deviation in the spatial position of the closed tube to be measured and due to the long-term pull rope effect of the stay rope, the elastic expansion and contraction of the stay rope causes the accuracy of closing to be greatly reduced, and the wear and tear of the stay rope causes the damage of the stay rope, which affects the performance and work efficiency of the measurement and increases the input of the cost. A simpler, higher measurement accuracy and less susceptible to interference portable closing pipe measurement method is what equipment manufacturers and equipment users are willing to look forward to

Abstract

The present invention discloses a device and method of field measurement of folding pipes on the basis of a three-dimensional space shooting positioning technology. Ends of two folding pipes are respectively provided with first flanges and second flanges. The device provided by the invention comprises a first high-precision camera, a second high-precision camera and a telescopic pole connecting the first high-precision camera and the second high-precision camera; the first high-precision camera and the second high-precision camera are respectively provided with three mutually vertical angle sensors, a plurality of plates are arranged on the first flanges and second flanges, and data acquisition cards are configured to store shooting images of the first flanges and the second flanges and the detection data of the angle sensors are installed in the first high-precision camera and the second high-precision camera. According to the invention, the accurate position of an object may be accurately obtained in a three dimensional space, so that an accurate and stable operation environment is provided for other operations, and therefore a lot of labor cost and the labor intensity is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to an on-site measurement device and method for a closing pipe based on three-dimensional space shooting and positioning technology, and belongs to the field of manufacturing and processing of closing pipes. Background technique [0002] There are pipes everywhere in the ship, and a series of operations such as the design and manufacture of these pipe fittings and the inspection after installation in the ship are called "pipe laying". Usually ships are built in sections, and the pipelines between the sections need to be connected by closing pipes when the sections are closed. However, various closing pipes are manufactured by relying on the pipeline design drawings. On-site welding method. [0003] The most difficult thing in pipe production is "to ensure good precision of the finished product". However, when using the above two methods, it often occurs that the flange bolts of the closed pipe manufactured are not in the correct...
