Problems solved by technology
The advantage of this method is that it can scan the hidden object surface data, and can scan the motion scanning data during interaction, but this scanning method cannot accurately scan the side information of the object and generate an accurate three-dimensional image
In the field of cultural relic scanning technology, it is often necessary to accurately display the information on the side of cultural relics such as stone steles, which cannot be achieved by current scanning technology.

Embodiment 1
[0048] A device for assisting three-dimensional scanning, such as Figure 2-4 As shown, the device includes a three-dimensional scanner and a plane mirror. Wherein the plane mirror is the front surface reflector. The front surface mirror is an optical element that is coated with a metal silver (or aluminum) film on the front surface of the optical glass by vacuum coating to reflect the incident light. Because it is reflected on the front surface, it can ensure that the reflected image is not distorted and has no ghosting. During use, the mirror surface of the plane mirror is set at an angle of 45° to the horizontal plane of the scanned item, and the mirror surface of the plane mirror is set at an angle of 135° to the platform of the three-dimensional scanner (such as figure 2 shown).
[0049] The plane mirror is placed on a movable slant plate, and there are 4 movable slant plates, one on each side of the object to be scanned, at an angle of 45° to the horizontal plane.

The invention discloses a device and method for assisting three-dimensional scanning, which belong to the technical field of three-dimensional scanning and image processing. The setup includes a 3D scanner and a plane mirror. The front surface reflector is an optical element that is coated with a metal film on the front surface of the optical glass by vacuum coating to reflect the incident light. When in use, the mirror surface of the plane mirror is set at an angle of 45° to the horizontal plane of the scanned object, and the mirror surface of the plane mirror is set at an angle of 135° to the platform of the three-dimensional scanner. The invention utilizes the reflection principle of a plane mirror, and places a plane mirror around the object to be scanned. While scanning the upper surface of the object, it also scans the side. point, the two depth maps are stitched together to obtain a three-dimensional map. The device for assisting three-dimensional scanning of the present invention is suitable for scanning cultural relic materials with a certain thickness, and can obtain comprehensive side information of cultural relics.
Description
technical field [0001] The invention belongs to the technical field of three-dimensional scanning and image processing, and in particular relates to a device and method for assisting three-dimensional scanning. Background technique [0002] At present, in the field of cultural relic scanning technology, there are high requirements for scanning accuracy, efficiency, and authenticity. Scanning equipment includes handheld scanners and large platform scanning equipment. Handheld device scanning needs to be carried out bit by bit, the scanning efficiency is low, and the scanned 3D images need to be spliced, the subsequent processing steps are more complicated, and the authenticity of the color is poor. [0003] Large-scale platform scanning equipment can obtain the depth map of objects. When using large-scale platform equipment to scan objects, the traditional method is to scan only one side at a time. Generally, it takes at least six times to scan a simple-shaped object, and th...
