What is the high-speed camera used for? What is its working principle? How is the scanning quality?

Recently, I have found that everyone is more concerned about this issue. To put it bluntly, Gaopaiyi scans things from the computer, or scans your own files onto the computer, and converts the scanned pictures into word documents.

What is the high-speed camera used for? Here is a brief introduction: First of all, the natural duty of a high-speed camera is to scan photos, books, newspapers and magazines quickly (1 second scanning) and save them to the computer after scanning. It has a variety of functions, such as: Document scanning, e-book production, physical photography, video recording, high-definition million video recording, signature production, and more! In recent years, Gaopaiyi has played a new trick, which is what people often call "OCR" (character recognition). With this technology, text written on paper can be scanned and automatically converted into editable files on the computer. This can greatly reduce the amount of text input when typing. Without further ado, let’s go straight to the picture:

Let’s briefly introduce the working principle of the high-speed camera! The principle of the high-speed camera is actually very simple, just like when we usually look in the mirror at home. Because there is a certain distance between the camera and the object to be scanned, in theory, the high-definition camera can scan anything as long as it is not higher than the triangle area between the camera and the ground plane. Therefore, the scanning size of the high-definition camera is relaxed, whether it is A3 Pictures, drawings, or 3D objects can all be scanned using a high-speed camera. The high-speed camera scanning software is one of the most important tools for high-speed camera to complete the scanning task. Pictures scanned by a high-definition camera must be exported through the software before they can be saved. In addition, users can also use this software to know in time whether the angle of the scanned items or pictures is appropriate, and make timely corrections and cuts.

So because the scanning principle used by the high-definition camera is different from that of traditional scanning equipment, its application in scanning is also very different from that of ordinary scanners.

Let’s talk about the scanning quality of the high-speed camera! Images scanned by high-definition cameras are prone to the following two problems. One is due to the instability of the external light source, resulting in a certain color difference between the scanned items and the image. The second is that the high-definition camera uses the principle of a digital camera. The scanned images have a lot of noise, which greatly damages the authenticity of the items being scanned.

In view of the above two reasons, it can be seen that the scanning quality of high-speed scanners may not be as high as that of most scanners. Because high-speed scanners have average performance in terms of scanning accuracy and color, they are currently only suitable for non-professional commercial pictures or documents that do not have very high requirements for accuracy and color.

Pictures obtained by scanning with a high-definition camera

Pictures obtained by scanning three-dimensional objects with a high-definition camera

Observing the documents and pictures scanned by a high-definition camera, we found that the Although the color of the picture is uneven due to the gloss of the machine, the picture is also distorted because it cannot be fixed. But the fonts on the document are still legible, and the details in the pictures are pretty good.

It is worth mentioning that the performance of Zhizhuo high-definition camera in scanning 3D three-dimensional objects is remarkable. In addition to color abnormalities caused by improper fill light, the details in the scanned physical images are still blurry. A good restoration can be obtained.

The above is the detailed introduction of Gaopaiyi, I hope it can help you!
