Abstract

The embodiment of the invention provides a scanning method and device, a scanning pen and a storage medium, and the method comprises the steps: extracting a spliced image frame from collected image frames based on the number of spliced interval frames, and updating the number of spliced image frames; if the number of the spliced image frames reaches an identification frame number threshold, identifying the images obtained by splicing all the spliced image frames; wherein the splicing interval frame number and the identification frame number threshold are determined based on the current scanning speed of a scanning pen. The scanning method and device, the scanning pen and the storage medium provided by the embodiment of the invention can adapt to different scanning speeds, thereby ensuringthat the quality of the acquired scanning image is enough to enable the image to be correctly spliced and identified, avoiding increasing redundant computation amount and data transmission amount, andimproving the identification efficiency of the scanning pen.

Description

Technical field

[0001] The invention relates to the technical field of electronic equipment, in particular to a scanning method, device, scanning pen and storage medium.Background technique

[0002] Scanning pen is a handheld electronic device. Users can press the pen tip to trigger the button to collect scanned images in real time, and through the built-in optical character recognition (Optical Character Recognition, OCR) module, it can realize text recognition, storage and editing Such operations are widely used in student learning, tourism translation and other scenarios.

[0003] When the user uses the scanning pen to scan, the scanning pen will collect images at a fixed frame rate. However, when the user's scanning speed is too fast or too slow, image acquisition at a fixed frame rate will cause missing or missing characters in the stitched image, or increase the amount of extra computation and data transmission.Summary of the invention

[0004] The embodiments of the present invention provi...
