Abstract

The invention discloses a close shot large span digital photogrammetry system and method. The system comprises a rectangular collecting platform, guide rails, cameras, a three-dimensional calibrating board and a two-dimensional control filed. The three-dimensional calibrating board comprises a plurality of calibrating marks distributed evenly, each calibrating mark comprises a cylindrical type wooden stick and a round wooden board on the top surface of each cylindrical type wooden stick, the cylindrical type wooden sticks of all the calibrating marks are different in height, and the cylindrical type wooden sticks of the calibrating marks located in the middle of the three-dimensional board are higher than those located on the peripheral of the calibrating marks. The two-dimensional control field comprises a plurality of control point marks distributed on the end face of the edge of the rectangular collecting platform, the control point marks form the control points of the two-dimensional control field, and each control point mark comprises a round wooden board. The close shot large span digital photogrammetry system and method can enable images to achieve the fidelity of high-precision geometrical information.

Description

technical field [0001] The invention relates to the technical field of aerial photogrammetry, in particular to a close-range large-format digital photogrammetry system and method. Background technique [0002] Static graphic cultural resources refer to flat, static and immovable two-dimensional calligraphy and painting works on different media. It mainly refers to the paintings and calligraphy collected in the library, such as calligraphy, oil paintings, silk paintings, paper paintings, prints, paper-cuts, rubbings, etc. This kind of static two-dimensional cultural resources is an important part of national cultural resources, carrying thousands of years of Chinese history and the cultural genes of nationalities and regions. The use of close-range photogrammetry technology to scan, digitize and archive cultural resources has far-reaching historical significance for the inheritance, sharing and development of cultural resources. [0003] In the process of developing high-pr...
