Description
Technical Field
The utility model relates to an accurate structure of three-dimensional figure draws the field, especially relates to an accurate automatic historical relic is automatic scanning device for modeling.
Background
According to statistics, at present, the cultural relics needing to be repaired, such as bronze wares, chinaware, calligraphy and painting, and the like in China are as many as 200 and more than ten thousand, which is a huge project. The large size is not only in the number, but the difficulty in repairing the cultural relics is one of the reasons for not repairing so many cultural relics. This not only requires a great deal of time and money, but also carries with it the risk of damage from improper repairs.
This difficult problem has just been solved to 3D scanning technique, and more traditional mode uses 3D scanning technique to gather data and has advantages such as fast, gather accurately, simultaneously because its non-contact's working method, the collection process can not lead to the fact secondary damage to porcelain itself, and high resolution imaging also can let the processing and the concatenation in later stage more accurate and perfect moreover.
However, one of the two mainstream 3D scanning technologies in the prior art is to attach a patch with a positioning function on the surface of an object and then perform manual handheld scanning, and the other is more advanced non-contact laser scanning, but for cultural relics made of some special materials (such as rusted metal bodies, calligraphy and painting, wood carving and the like), irreversible damage can be caused to the cultural relics by the surface patch or laser irradiation, and a corresponding solution does not exist in the prior art at present.
Therefore, an automatic scanning device for automatic cultural relic modeling, which is automatic, mechanically displaced, precisely focused, scanned at a time and reduced in manual error, is urgently needed in the market.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an automatic, mechanical displacement, accurate focusing, once accomplish scanning, reduce the accurate automatic scanning device for historical relic modeling of artificial error.
In order to achieve the above purpose, the utility model adopts the following technical scheme: an accurate automatic scanning device for automatic cultural relic modeling comprises an automatic mechanical scanning device, a target area and a central control system;
the automatic mechanical scanning device consists of a base, a horizontal rotating shaft arranged on the base, a front and back displacement rotating shaft arranged on the horizontal rotating shaft, a lifting rotating shaft connected with the upper part of the front and back displacement rotating shaft through a metal arm, a lens rotating shaft connected with the front part of the front and back lifting rotating shaft through a metal arm, and a lens which is fixed with the front end of the lens rotating shaft and is internally provided with an optical automatic zooming structure;
the target area consists of a supporting structure, a rotating shaft of an object bearing table which is arranged in the supporting structure, and a rectangular object placing platform which is fixed with the upper end of the rotating shaft of the object bearing table;
the central control system is respectively connected with the object bearing table rotating shaft and the automatic mechanical scanning device in the supporting structure, and a power supply, a data contrast analysis device connected with the lens and a mechanical linkage control system connected with the object bearing table rotating shaft, the lens rotating shaft, the horizontal rotating shaft, the front and back displacement rotating shaft, the lifting rotating shaft and the data contrast analysis device are arranged in the central control system.
The utility model discloses in, the position relation of the automatic mechanical scanning device of central control system control and target area is: the method comprises the steps of aligning a lens to a cultural relic to be scanned placed on a target area by controlling an automatic mechanical scanning device, completing scanning of a three-dimensional structure of a single surface of the cultural relic by three scanning angles of 15-45 degrees of overlooking angle, -5 degrees of head-up angle, -30-15 degrees of elevation angle until a data contrast analysis device completes complete structure construction, then rotating a rotating shaft of a bearing platform by 30-60 degrees, reserving a part of characteristic area in the previous scanning, repeating the previous triangular scanning, completing complete construction of a second scanning structure through the data contrast analysis device, simultaneously performing automatic splicing by utilizing the characteristic area overlapped by the second scanning and the first scanning, completing integration of the two times of scanning, and repeating the steps until a three-dimensional model of the cultural relic is completely constructed.
Compared with the prior art, the utility model has the advantages of it is following: (1) the real-time feasible scheme that the three-dimensional coordinate system without contact of hands of the session automation is used for the datamation model mapping of valuables and special materials which cannot be directly pasted with the labels is put forward for the first time. (2) The utility model discloses set up different angles, different positions scanning and hold thing platform autogiration function, can make up the stack when the scanning and survey repeatedly the region of surveying and drawing more, then survey shape, the size of drawing more accurate, lose also can improve to a great extent because of the rotatory coordinate point that leads to of spatial structure or upset. (3) The utility model discloses a mechanical structure is five-axis linkage structure actually, though abandoned all-round, the full angle machining ability of industry five-axis machining, has nevertheless emphatically strengthened in the aspect of the multiaxis linkage to the mark historical relic place region, and consequently its precision in specific direction is high, also is greater than artifical handheld scanning device's precision far away certainly. (4) The utility model discloses a special practicality achievement to the intensive research acquisition of valuable historical relic scanning characteristic is applicable to most high-end historical relic scanning, survey and drawing, modeling. Therefore, the utility model discloses have automatic, mechanical displacement, accurate focus, once accomplish the characteristic of scanning, reduction hand error.
