Method for positioning shooting documents by square of document shooting instrument

Abstract

The invention discloses a method for positioning shooting documents by a square of a document shooting instrument. The method is characterized in that three main functional parts, i.e., a shooting instrument, an image capturing and processing module built in the shooting instrument and a positioning piece which can be placed at will and identified by the image capturing and processing module, are utilized. The positioning piece is a square with two right-angle sides and has the thickness for positioning stacked files. With the adoption of the system, slope angle adjustment, clipping and magnification of the image can be accomplished, and then a plurality of documents can be shot once. The positioning square is not needed to be fixedly connected with the shooting instrument and can be placed at will. The required rotation angle is calculated after positioning by the positioning square, and tidy shot pictures with clear image quality are finally obtained through picture adjustments, clipping and magnification.

[0002] The document camera is a common electronic product in the office. Its function is to convert paper text and pictures into electronic documents by taking pictures, which is convenient for sending and transmitting through the network, and speeds up the exchange and transmission of information and information. , which smooths the work and life of modern people. This kind of document capture device usually needs to use a camera with a certain height to capture the documents placed in the field of view below the camera. This has a problem of shooting positioning. The shooting range of the camera It is limited, and the part of the file cannot exceed the shooting range. On the other hand, in order to make the obtained picture effect clearer, the captured original picture should occupy the entire picture of the shooting screen as much as possible. In this case, put the paper on the When shooting under the lens, two problems often occur. The first problem is: the paper is placed on a plane without borders, and the documents cannot be placed accurately until it is accurately aligned with the field of view of the camera lens. It is tilted or offset. The second problem is: when the first paper is adjusted and corrected, when the second paper is placed on the first paper for the second shooting, also because there is no frame, the second One piece of paper will continue to deviate, so that the second piece of paper needs to be adjusted again to align; if multiple papers are photographed continuously, it is even necessary to adjust and arrange each document. This state of inaccurate positioning and correction makes the There is a lot of inconvenience when users use it, which has caused obstacles to the widespread use of document shooting instruments

Some existing products use a fixed positioning part attached to the base part of the document shooting instrument. In order to ensure that the positioning part can be aligned with the lens, it is fixedly connected. After a period of use, it is necessary to regularly calibrate the positioning part and the lens to shoot The focal point of the angle coincides with one point, and then the document to be photographed is placed according to the positioning of the positioning piece. The defect of this method is that once such a square structure is attached to the document photographing instrument, it is impossible to make a small and portable document. The camera increases the volume of the entire device, and it is inconvenient to place it in batches when shooting a large number of files.

What's more, a wider flat metal positioning plate is used to place and position on the metal positioning plate. The disadvantage is that the metal material of the positioning plate makes the whole device more bulky
