Embodiment Construction

[0011] Such as figure 1 As shown, an original handwriting recording smart pen based on inertial measurement, a USB interface 10 is provided on the top of the pen holder 12, and a microphone 11, a wireless communication module 9, a power management unit 8, and a processor 7 (model : MT6260A, manufacturer: MediaTek), pressure sensor 5 (model MPL3115A2, manufacturer: Freescale), battery 6, acceleration sensor 4 (two 3-axis acceleration sensors, model: KXTJ2-1009, manufacturer: Kionix), infrared lamp 3 and camera 2 (model: GC0328, manufacturer: Geke Microelectronics), the pressure sensor 5 is connected with the refill 1. Camera 2 is used to obtain writing data on paper, to determine the position of the pen tip on the paper and the parameters of the acceleration sensor (the yaw angle, pitch angle, roll angle, etc. of the acceleration sensor relative to the paper surface) . There are marks on the paper used for writing, so that the camera can complete the acquisition of the above-...

Abstract

The invention relates to a pen and particularly relates to an intelligent original handwriting recording pen based on inertia measurement, which mainly solves the technical problems of an existing intelligent pen that special patent paper needs to be used, the cost is high and the pen is not convenient to carry. According to the intelligent original handwriting recording pen based on the inertia measurement provided by the technical scheme, a USB (Universal Serial Bus) interface is arranged at the top of a pen holder; a microphone, a wireless communication module, a power supply managing unit, a processor, a pressure sensor, a battery, an acceleration sensor, an infrared lamp and a camera, and a refill connected with the pressure sensor are sequentially arranged in the pen holder from top to bottom. The processor is connected with the camera, the infrared lamp, the acceleration sensor, the pressure sensor, the wireless communication module, the microphone and the USB interface respectively; the power supply managing unit is connected with the battery, and is connected with the processor, the camera, the infrared lamp, the acceleration sensor, the pressure sensor, the wireless communication module and the USB interface respectively. The intelligent original handwriting recording pen can be used for writing on the paper and can be used for recording an original handwriting.

Description

technical field [0001] The invention relates to a pen, in particular to a smart pen for recording original handwriting based on inertial measurement. The invention can write on paper and record original handwriting. Background technique [0002] Currently on the market, smart pens that can write on paper and record original handwriting mainly include "image recognition type" and "radio frequency positioning type". The "image recognition type" uses a miniature high-speed camera placed on the tip of the pen to scan the handwriting by an image recognition algorithm; the "radio frequency positioning type" places an ultrasonic receiver near the writing surface to complete the three-dimensional positioning of the brush strokes by means of ultrasonic waves . "Image recognition type" requires a high-speed camera and a powerful processor for image processing (livescribe's smart pen requires a 70 frames per second camera, ARM9 processor), and uses special paper with patented technolo...
