Digital reproducing auxiliary system for Chinese calligraphy and paintings

Abstract

The invention discloses a digital reproducing auxiliary system for Chinese calligraphy and paintings, which comprises a system frame, a picture taking assembly, a lighting assembly, a picture hanging bracket and a picture horizontal-draught assembly, wherein the system frame is used for causing the picture taking assembly and the lighting assembly to move along the direction of a guide rail; the picture taking assembly is used for supporting a large-format digital camera and can move in the horizontal direction and the upright direction perpendicular to the guide rail; the lighting assembly is used for supporting a light box and can cause the light box to move in the upright direction and rotate around an upright shaft; the picture hanging bracket can move in the upright direction to adapt to the height of the format and can adjust the distance between hooks to adapt to the width of the format; and the picture horizontal-draught assembly is used for smoothly fitting format media. The lighting assembly is arranged between the picture taking assembly and the picture horizontal-draught assembly, and the picture horizontal-draught assembly is composed of an adsorption flat box body, a negative-pressure gas tank and a negative-pressure pump. One surface of the adsorption flat box body fitted with a format has uniformly distributed micropores, and the other surface is communicated with the negative-pressure gas tank through a pipeline. The system greatly increases the photo taking quality, reduces the labor intensity, and is particularly suitable for a large-batch reproducing operation.

Description

technical field [0001] The invention relates to a digital remake auxiliary system, in particular to a digital remake auxiliary system applied to Chinese calligraphy and painting works. Background technique [0002] When collecting image archives or copying precious calligraphy and painting works, it is necessary to collect digital image information first, which is commonly referred to as copying and scanning. The currently known method with the best effect is to use a professional large-format scanner, but large-format scanners are extremely inconvenient to operate on scrolls in Chinese calligraphy and painting, have size restrictions, and are also very expensive. Therefore, the industry usually still focuses on remakes with professional large-format technical cameras. At present, technical camera remakes rely entirely on artificially arranging lighting, adjusting shooting distances and angles. This approach has many defects: 1.

AI Technical Summary

Problems solved by technology

At present, technical camera remakes rely entirely on artificially arranging lighting, adjusting shooting distances and angles. This approach has many defects: 1. The efficiency is very low, and there will be certain errors in each operation, which will affect the quality of shooting, especially batch shooting. 2. When the calligraphy and painting works are hung, it is difficult to level off and easy to swing, which affects the shooting effect.

3. It is difficult to find the center of the subject by visual inspection. If the camera is not at the center of the subject, the image will deteriorate due to the optical distortion of the camera lens.

4. It is difficult to find the ideal light angle between the light and the subject by visual inspection, and the unsatisfactory light angle will affect the image quality
