Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] When the user uses the tip of the scanning pen to scan the text on paper documents or books at a constant speed, the built-in camera of the scanning pen will collect images at a certain frame rate for image recognition by the optical character recognition module, and obtain the text in the user's scanned image. Word. Wherein, the frame rat...

Abstract

The embodiment of the invention provides an image acquisition method and device, a scanning pen and a storage medium, and the method comprises the steps: obtaining a current scanning speed based on aroller disposed at a pen point of the scanning pen; determining a shooting frame rate corresponding to the current scanning speed; and performing image acquisition based on the shooting frame rate. According to the image acquisition method and device, the scanning pen and the storage medium provided by the embodiment of the invention, the current scanning speed is acquired based on the roller arranged at the pen point of the scanning pen, and the shooting frame rate corresponding to the current scanning speed is determined, so that image acquisition is performed based on the shooting frame rate, and self-adaptive adjustment of the shooting frame rate of the camera can be achieved; therefore, it is ensured that the quality of the collected scanned image is enough to be correctly recognized,and meanwhile, excessive images with high overlap ratio are prevented from being collected, and excessive calculation amount and data transmission amount are prevented from being increased.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an image acquisition method, device, scanning pen and storage medium. Background technique [0002] The scanning pen is a hand-held electronic device. The user can scan and input text or images by holding the scanning pen. Through the built-in optical character recognition (OCR) module, the text can be recognized, stored and edited. It is widely used in scenarios such as student learning and tourism translation. [0003] When the user uses the scanning pen to scan, the scanning pen will perform image acquisition at a certain frame rate. However, the current scanning pen usually collects images at a fixed frame rate during use, so that when the user's scanning speed is too fast or too slow, the image recognition rate will be reduced, or redundant calculation and data transmission will be increased.
