Technical Field
The utility model belongs to the technical field of object imaging, and particularly relates to a high-resolution scanning splicing imaging device.
Background
High resolution imaging of objects is an important application, such as scanning of artwork, calligraphy and painting, wood grain stone, plant specimens, and the like. At present, there are many common digital acquisition technologies for planar objects, such as a planar scanner and a high-precision digital camera.
Generally, the digitization of the object is more performed by planar scanning. Such scanners typically employ a linear array detector, i.e., each scan is performed by acquiring a line, stepping the line in the other direction, and finally stitching the acquired lines into a complete image. Due to the process limitation of the CCD, the breadth and the resolution ratio are difficult to further improve, and the change is difficult after the manufacture and the shaping, so the expansibility and the adaptability are limited. The other method is to adopt a high-precision digital camera, and can flexibly obtain images by adapting to different distances and different focal lengths of lenses, but the resolution is limited by the resolution of the camera. The high-precision digital camera is combined with a motion mechanism to carry out plane scanning splicing imaging, and the method is a better expansion mode. However, the digital camera scanning splicing imaging is generally difficult to achieve higher resolution, and under the condition of high resolution, the depth of field of a shot object is difficult to ensure.
Therefore, the above problems are further improved.
