Problems solved by technology

[0006] The technical problem to be solved by the present invention is that, in view of the prior art, traditional photographic three-dimensional data reconstruction needs to be photographed at multiple distances at multiple specific angles in the three-dimensional space, and the corresponding light source needs to be adjusted for each photographing, so as to To ensure the shooting accuracy of the surface texture, the efficiency is low, and there are many human interventions, and the technical defects of the overall accuracy fluctuate greatly, provide an automatic three-dimensional high-definition camera cultural relic data protection device and method

Embodiment 1

[0066] The width of the upper main bracket strip is W=100mm, and the thickness is 8mm. The first semi-circular arc band 1 and the second semi-circular arc band 2 are made of Q460 material, the yield strength is required to be above 460MPa, and the tensile strength is required to be above 540MPa .

[0067] The height of the light center is 80mm from the surface of the first semi-circular arc zone 1 and the second semi-circular arc zone 2. The lighting source 4 at each position must be consistent, and the error should be controlled within 2mm. The lens 7 is installed on the camera 6, the effective pixels are 42 million, the ISO sensitivity meets ISO 50-102400 for static images, and ISO 100-32000 for dynamic images. On the same orientation on the first and second semicircle circular arc belts 1 and 2, that is, the lighting lamp holder is provided with a lighting source 4, and the luminous intensity of each hole is more than 150cd, and the luminous flux is 1100lm.

Embodiment 2

[0076] The bracket structure adopts the same scheme as in Embodiment 1. The lens 7 is installed on the camera 6, and the effective pixels are 45 million. The ISO sensitivity of static images meets ISO 50-102400, and that of dynamic images meets ISO 100-32000. On the first semi-circle arc zone 1 and the second semi-circle arc zone 2, on the same position, that is, on the lamp holder, there is an illumination lamp source 4, the luminous intensity of each hole position is above 170cd, and the luminous flux is 1300lm.

Abstract

The invention discloses an automatic three-dimensional high-definition camera cultural relic data protection device and method. The invention can realize efficient, high-precision and stable collection of cultural relic data, plays an important role in the inheritance and protection of cultural relic data, and can automatically perform multi-angle protection of cultural relics. , no shadow data collection, and multi-machine shooting at the same time, the collection efficiency is several times to dozens of times that of the traditional method, and because the relative position of the camera position and the supply light source is fixed, it has the characteristics of accurate positioning, uniform lighting, and stability, and no one is involved in the whole process. Intervention ensures data accuracy and high stability.

Description

technical field [0001] The invention relates to a cultural relic data protection device and method based on three-dimensional high-definition imaging, which mainly uses high-definition three-dimensional imaging technology to protect cultural relic data, and belongs to the field of cultural relic protection and photography. Background technique [0002] As soon as photography technology came out in 1839, people began to use images to conduct various measurement research on target objects. Traditional photogrammetry (Photogrammetry) is a discipline that uses images to study the shape, size, position and other information of the subject. The rich image information of the subject is truly expressed through the image, and people can obtain a large number of three-dimensional images of the research object. information. With the improvement of measurement accuracy requirements and the continuous improvement of technical means and equipment levels, photogrammetry has also developed...
