Embodiment

[0079] Taking the murals in Cave 3 of Dunhuang as an example, the process of obtaining them is as follows:

[0080] Divide the murals in the cave and determine the shooting platform to be used. According to the situation in the third cave, we divide it into nine flat murals and twelve turning connections. The flat murals all use the ordinary shooting platform, and the murals at the turning joints use the ordinary shooting platform and the vertical turning point shooting platform respectively;

[0081] Measure and map the size of murals to determine the size of each mural;

[0082] According to the content of the mural, determine the resolution requirement: 3pixel / mm;

[0083] Calculate the coverage area of ​​each photo: 30inch×20inch; calculate the number of photos for each mural; draw a wall division map and make a record form;

[0084] For each mural, complete the following two steps:

[0085] 1) Install the shooting bracket, flashlight and camera, and adjust them accord...

Abstract

A method based on digitalizing technique for copying ancient wall painting in cave includes such steps as dividing the wall painting by position classification method, determining photographic plan by using resolution calculation method according to mapping result of wall painting, recording photographic condition in tables, regulating flash lamp for taking white plate shot, taking the photo on platform, and processing and splicing the images by computer.

Description

technical field [0001] The invention relates to a method for acquiring cultural relics of ancient cave murals and a shooting platform based on digitization technology. Background technique [0002] The traditional way to preserve and record the cave murals is to record the murals on film and tape by means of photography and videography. However, these traditional photography methods cannot achieve a good preservation effect, and can only provide a rough image, which is far from the purpose of recording. However, there is no common standard for ordinary digital acquisition methods, and there are shortcomings such as irregular operations and unsatisfactory effects. Contents of the invention [0003] The purpose of the present invention is to provide a digital technology-based acquisition method and shooting platform for ancient cave murals and cultural relics. [0004] The steps of the acquisition method of ancient cave m...
