Certain words used to describe the present application are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the present application.

The utility model relates to a novel glasses shell, as shown in figure 1, figure 2 and figure 3, a fold and manage measuring device, including taking a picture device 1, a set of reference scale 2, measuring frock 3 and data processing module 4, wherein, it is single anti-camera to take a picture device 1, the reference scale adopts carbon fiber material to make, reference scale 2 is rectangular form, 3 strong magnets 21 are pre-buried in the inside of reference scale 2, the upper surface of reference scale still is equipped with code mark 22, code mark 22 includes first code mark, second code mark, third code mark and fourth code mark, wherein, as shown in figure 4, be equipped with 8 coordinate value 221 of point on the code mark;

the measuring tool is used for rapidly arranging measuring points on the flange hole, the measuring tool 3 comprises a fixed end 31 and an inserting end 32, the inserting end 32 is connected with the fixed end 31 and is cylindrical, and the diameter of the inserting end is smaller than that of the fixed end.

Through the content, it is not difficult to discover that the three-dimensional coordinate of the closed pipe flange hole can be measured quickly, accurately and automatically by adopting an industrial photogrammetry principle, designing a special reference ruler and a measuring tool and matching with automatic processing software, and in addition, 3 strong magnets are pre-embedded in the reference ruler and adsorbed on a ship body, a pipe and the like, so that the taking and the placing are very convenient.

The specific measurement method comprises the following steps: the procedure for measuring the closure tube using this system is as follows:

1) the measuring tool is inserted into the 4 symmetrical holes of each flange, and the measuring marks on the two flange tools face the same direction as far as possible (and the direction is convenient for photographing) through the rotating tool.

2) And uniformly placing a reference scale near the flange, wherein the orientation of the surface of the reference scale, which is pasted with the coding mark, is consistent with that of the measuring tool as much as possible.

3) And taking about 20-40 photos at different positions within the range of about 0.5-2 m in front of the flange, introducing the photos into a computer, and automatically analyzing by data processing software to obtain the three-dimensional coordinates of the tool points.

In the embodiment, the code marks are fixed on the reference ruler in an adhering mode, and the code marks are fixed together in an adhering mode, so that the code marks can be tightly connected together without moving, and the code marks are firmer.

Specifically, the length of reference scale is 350mm, one set of reference scale includes 10 with the reference scale, so this reference scale possesses reference scale, directional target, the function that the code was marked simultaneously, as long as adsorb the reference scale of sufficient quantity near the flange that awaits measuring can, no longer need place directional target and code mark in addition.

In addition, it should be noted that the measuring tool is made of an aluminum alloy material, an inclined plane is arranged on the fixed end, and an included angle of 45 degrees is formed between the inclined plane and the horizontal plane.
