Written content detection system and method based on acceleration sensors

Abstract

The invention discloses a written content detection system based on acceleration sensors. The system comprises a pen body and a microprocessor, wherein the pen body is provided with at least one acceleration sensor module from top to bottom and outputs digital voltage signals to the microprocessor; the microprocessor comprises a training module and a detection module; the training module establishes a detection model according to the difference between acceleration data glitches collected when a user writes on paper and when the user does not write on paper; and the digital voltage signals ofthe acceleration sensor modules are collected in the real-time monitoring process and input into the detection model, the action of the user who writes on paper and the action of the user who does notwrite on paper are distinguished, action tracks are calculated through acceleration data corresponding to the action of the user who writes on paper and the action of the user who does not write on paper, the tracks are connected with a line, a motion track of a pen in the writing process is obtained, and finally written content is obtained. Through the system, written content detection can be completed when an image is inconvenient to collect.

Description

technical field [0001] The present invention relates to a wearable device, in particular to an intelligent detection system and method for realizing human body motion monitoring, especially writing content detection. Background technique [0002] Modern writing content detection basically detects content through image processing methods, which have certain requirements for the clarity and validity of the obtained images, and are not suitable for some scenes where images cannot be collected.
