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

Embodiment 1

[0060] like figure 1 As shown, a movable artifact time domain data acquisition platform includes a rack 1, a sealing platform 2, an image acquisition apparatus 3, and a control system, and the belt platform 2 is disposed on the frame 1, and the object platform 2 is provided with a transparent The rotating disk 4, the created article is placed in the middle of the rotary disk 4, and the rotary disk 4 can rotate at the horizontal plane at the driving plate at 360 °, and the chassis 10 is also provided with a chassis 10, chassis 10. A drive arm 5 is provided on one side of the sealing platform 2, the image acquisition device 3 is disposed on the drive arm 5, and the drive arm 5 is provided with a rotating shaft 11 in a horizontal direction. The drive arm 5 carries the image acquisition device 3 winding shaft. 11 In the vertical plane swing, a first limit device 13 is also provided on the chassis 10, the first limit device 13 being vertically disposed on both sides of the rotating sha...

Embodiment 2

[0091] like Image 6 As shown, in the present embodiment, in the present embodiment, the driving method of the rotary disk 4 is a belt drive, and the platform 2 further includes a first motor 6, a guide wheel 8, a belt 9, which is The first motor 6 is connected to a gear unit, and the belt sheet is fastened to the reticle output shaft and the guide wheel 8, the belt is closely fitted with the rotating disk 4, the first motor 6 drives the belt 9 to move the rotary disc. 4 Rotate 360 ​​° on the horizontal plane, the artifact on the rotary disk 4 can be realized, image acquisition is performed at any angle of the same horizontal plane 360 ​​°.

Embodiment 3

[0092] Example 3 (not shown in the figure):

[0093] Unlike Example 1, in the present embodiment, an external light source is also provided on the object platform 2, and the external light source is disposed outside an external LED photographic lamp, an external LED photograph lamp The actual situation sets different light source locations, providing good light to the cultural image acquisition, allowing the image to capture the light corner and shadow, enhance the texture and clarity of the image.

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...
