Movable cultural relic time domain data acquisition platform and acquisition method thereof

Abstract

The invention belongs to the technical field of image data acquisition, relates to a movable cultural relic time domain data acquisition platform and an acquisition method thereof, and solves the problem that cultural relic image data acquisition is incomplete. The technical scheme is that the movable cultural relic time domain data acquisition platform comprises a rack, a storage platform, an image acquisition device and a control system, the storage platform is arranged on the rack, the storage platform is used for bearing a to-be-measured object and driving the to-be-measured object to rotate, the image acquisition device is used for performing image acquisition on the to-be-measured object at various angles, and the control system is connected with the storage platform and the image acquisition device. The objective of the invention is to realize accurate copying of texture, texture and dimensional precision of cultural relics through three-dimensional 720-degree data acquisition of the platform for specific objects which cannot be acquired by using a traditional three-dimensional scanning technology, especially vulnerable specific objects, so that the cultural relics not only can meet sensory cognition, but also can be directly used as samples researched by professionals, and the purposes of accurate copying and permanent recording is realized.

Description

Technical field [0001] The present invention belongs to the field of image data acquisition, and specific relates to a movable artifact time domain data acquisition platform and a acquisition method thereof. Background technique [0002] The digital record of cultural relics is very important. In terms of cultural relics, it is possible to retain its original appearance as much as possible in the current stage for a large number of corrosion oxidation. In view of appreciation and research, scholars, enthusiasts and collectors can easily or quickly watch and study artifacts anywhere and any time through the network, and will not cause any damage to the cultural relics. The digital record and exhibition form of cultural relics are mostly the following three forms: [0003] First, the form of a flat picture can only show a static picture of one side of the shooting cultural relics, only one angular image of the scene, even a wide-angle lens, can not effectively and comprehensively p...

Problems solved by technology

[0007] However, this device still has the following disadvantages: 1) The angle between the acquisition device and the measured cultural relic is distributed between 0° and 90°, and the relative position cannot be adjusted, so it is impossible to collect data on the image of the lower part of the cultural relic, and it cannot achieve 720° without dead angle Data acquisition; 2) The relative distance between the rotation platform and the acquisition device is fixed. For cultural relics of different volumes and profiles, the distance between the acquisition device and the cultural relics will affect the measurement accuracy; 3) There are 6 data collectors in total, each collecting The collected cultural relics are too small, which will also affect the accuracy of the final result. 4) For liquid, black, too small, strong light, high reflection, high transparency, hollow, and precise The image acquisition of objects with small gaps or small gaps will cause a double loss in the dimensionality of the material properties of the object itself and the representation accuracy, which will not achieve the purpose of accurate reproduction
