Embodiment 1

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

[0067] The height of the center of the light is 80mm away from the surface of the first half-circle arc belt 1 and the second half-circle arc belt 2. The illumination light source 4 in 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 still image meets ISO 50-102400, and the dynamic image meets ISO 100-32000. On the orthogonal first half-circle arc belt 1 and the second half-circle arc belt 2 in the same orientation, that is, the illuminating lamp holder is provided with a illuminating lamp source 4, the luminous intensity of each hole position is above 150cd...

Embodiment 2

[0076] The bracket structure adopts the same solution as in the first embodiment, the camera 6 is equipped with a lens 7 with 45 million effective pixels, ISO sensitivity static images meet ISO 50-102400, and dynamic images meet ISO 100-32000. On the first half-circle arc belt 1 and the second half-circle arc belt 2 in the same orientation, that is, the illuminating lamp holder is provided with a illuminating lamp source 4, and the luminous intensity of each hole position is more than 170cd, and the luminous flux is 1300lm.

[0077] Use manual shooting mode

[0078] 1. Place the cultural relic "Guizhou Wooden Mask" on the rotating stage 10 before shooting.

[0079] 2. Input the shooting angles to the controller 12, α0=0°, α1=10°, α2=20°, α3=30°, α4=40°, α5=50°, α6=70°, α7=80° , Α8=90°, α9=110°, α10=120°, α11=130°, α12=150°, α13=170°, α14=180°, α15=190°, α16=210°, α17=220° , Α18=230°, α19=250°, α20=270°, α21=280°, α22=300°, α23=310°, α24=330°, α25=340°.

Abstract

The invention discloses an automatic three-dimensional high-definition camera shooting cultural relic data protection device and method. According to the invention, high-efficiency, high-precision andstable collection of cultural relic data can be realized. The method plays an important role in cultural relic data inheritance and protection. Multi-angle shadow-free data acquisition can be automatically carried out on cultural relics, multi-camera simultaneous shooting is carried out, and the acquisition efficiency is several times to dozens of times that of a traditional method. Meanwhile, due to the fact that the relative positions of a camera position and a replenishment light source are fixed, the characteristics of accurate positioning and uniform and stable lighting are achieved, nohuman intervention exists in the whole process, and data precision and high stability are guaranteed.

Description

Technical field [0001] The invention relates to a cultural relic data protection device and method based on a three-dimensional high-definition camera, which mainly uses high-definition three-dimensional camera 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 studies on target objects. Traditional photogrammetry (Photogrammetry) is a discipline that uses images to study the shape, size, position and other information of the object. The rich image information of the object is truly expressed through the image, and people can obtain a large number of three-dimensional objects from it. information. With the improvement of measurement accuracy requirements and the continuous improvement of technical means and equipment, photogrammetry has also developed from analog photogrammetry a...
