Background

The wand is a hand-held electronic device, and the user can realize the scanning of characters or image through holding the wand and type, through built-in Optical Character Recognition (OCR) module, can discern, operation such as storage and editing to the characters, by wide application in scenes such as student's study, tourism translation.

At present, the scanning pen capable of supporting intelligent recognition and translation is deeply loved by parents and children, when the scanning pen encounters an incomprehensible word, paraphrases can be known only by scanning one scan, learning and communication are very facilitated, but the scanning pen on the market at present intelligently depends on one end of a touch pen point to press and trigger recognition, the pen point needs to be dragged to scan every time for recognition, a scanning area scans along with the dragged position, and the scanning pen is not beneficial to global scanning (for example, a whole page of books are recognized).

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide a scanning pen and a method capable of realizing global identification scanning.

In order to achieve the purpose, the invention adopts the following technical scheme:

a scanning pen capable of realizing global identification scanning comprises a scanning pen main body, a display screen, a first sliding rail, a second sliding rail, a rotating shaft and a camera module; the first sliding rail is arranged on the front side of the scanning pen main body and is positioned above the display screen; the first slide rail is positioned on the side surface of the scanning pen main body, and one end of the first slide rail is butted and communicated with one end of the second slide rail; the rotating shaft can slide back and forth between the first sliding rail and the second sliding rail;

the camera module comprises a camera and a support rod, and the camera is connected to the lower end of the support rod; the upper end of the supporting rod is hinged with the rotating shaft and can rotate up and down around the rotating shaft;

the built-in permanent magnet of bracing piece, the inside electro-magnet that is equipped with of wand main part, electro-magnet, camera and display screen equal electric connection in the inside master control of wand main part.

The invention discloses a method for carrying out global identification scanning by using the scanning pen, which comprises the following specific processes:

when a user triggers a global scanning event, the main controller applies instantaneous current to the electromagnet to enable the electromagnet to generate magnetic repulsion force, and the supporting rod bounces upwards under the action of the magnetic repulsion force;

In this embodiment, the top and the bottom of the first sliding rail and the second sliding rail are both provided with a recessed space, and the top and the bottom of the rotating shaft are respectively movably embedded into the recessed space so as to be always kept in the space of the first sliding rail and the second sliding rail. The butt joint of the first sliding rail and the second sliding rail is kept to be deep enough, so that the rotating shaft can smoothly transit between the first sliding rail and the second sliding rail.

Example 2

The present embodiment provides a method for performing global identification scanning by using the scanning pen described in embodiment 1, which specifically includes the following steps:

when a user triggers a global scanning event (the user can press a physical key, click a set position of a display screen, send a voice command and other conventional modes), the main controller applies instantaneous current to the electromagnet to enable the electromagnet to generate magnetic repulsion force, and the supporting rod bounces upwards under the action of the magnetic repulsion force;

a user pulls the supporting rod according to the requirement of adjusting the scanning area, so that the rotating shaft slides along the first sliding rail or the second sliding rail or between the first sliding rail and the second sliding rail; in the process, the camera scans and transmits an image obtained by scanning to the main control, the main control displays the image on the display screen in real time, and a user accurately adjusts the image to a required scanning area according to the image displayed on the display screen;
