Embodiment 1

[0031] Embodiment 1 of the present invention discloses a track recording device, which is suitable for writing materials, such as figure 1 As shown, it includes: a refill 1, at least two cameras (camera one 21 and camera two 22), a processor 3 and a memory 4. Wherein, the pen core 1 is used to leave handwriting on the material for writing. At least two cameras are used to capture each channel of current images, wherein each channel of current images includes at least handwriting. Processor 3, configured to receive each channel of current images, and acquire each channel of historical moment images corresponding to each channel of current images, and calculate the relative displacement between the reference points in each channel of current images and the reference points in each channel of historical moment images . The memory 4 is used for storing various channels of current images and various channels of historical moment images.

Embodiment 2

[0040] Such as figure 2 As shown, a track recording device disclosed in Embodiment 2 of the present invention includes: a refill 21, at least two processors (camera one 221 and camera 222), a processor 23 and a memory 24, and also includes:

[0041] The switch 25 that is connected with processor is used for judging whether pen core 21 contacts the material for writing, sends start, stop signal to processor 23, and processor 23 controls at least two cameras to start and stop capturing each channel according to start and stop signal. current image.

[0042] In Embodiment 2 of the present invention, the switch 25 includes a pressure sensor and a tact switch.

[0043] It should be noted that when the pen tip 21 is in contact with the writing material for writing, the switch 25 sends a start signal to the processor 23, and the processor 23 controls at least two cameras to start capturing each current image according to the start signal. When the nib 21 and the material for writi...

Embodiment 3

[0046] Such as image 3 As shown, a track recording device disclosed in Embodiment 3 of the present invention includes a refill 31, at least two cameras (camera one 321 and camera 322), a processor 33, a memory 34 and a switch 35, and also includes: a packaged pen The core 31 , the processor 33 , the memory 34 and the pen holder 36 of the switch 35 , at least two cameras are arranged on the pen holder 36 , facing the pen core 31 .

[0047] In the third embodiment of the present invention, the material of the penholder includes but not limited to metal and plastic. It should be noted that the plastic has good plasticity and can be molded into various shapes of the pen body for users to choose; of course, the pen body can also be made of metal material, so that the pen body has good strength and enhances durability.

[0048]With the track recording device disclosed in Embodiment 3 of the present invention, no additional device is needed in the process of track recording, the st...

Abstract

The invention discloses a track recording device which is adaptive to materials for writing. The track recording device comprises a cartridge, at least two cameras, a processor and a memorizer, wherein the cartridge is used for making writing marks on the materials for the writing, the at least two cameras are used for capturing all-path current images, the all-path current images at least comprise the writing marks, the processor is used for receiving the all-path current images and obtaining all-path historical moment images corresponding to the all-path current images and calculating the relative displacement of the reference points in the all-path current images and the reference points in the all-path historical moment images, and the memorizer is used for storing the all-path current images and the all-path historical moment images. According to the track recording device, additional devices are not needed in the track recording process, the structure of the track recording device is simplified, the track recording device is convenient to carry, and thus the range of application is enlarged.

Description

technical field [0001] The invention relates to the technical field of track recording, in particular to a track recording device. Background technique [0002] At present, there are two main ways for the stylus to record the track on paper: [0003] Method 1: Print the invisible code on the paper, and the camera installed on the stylus can realize the positioning by recognizing the invisible code on the paper, so as to realize the track recording. In the first method, the invisible code needs to be printed on the paper in advance, and the track record cannot be realized on the ordinary paper. [0004] Method 2: By adding an ultrasonic positioning device to the outside of the stylus, the pen tip is positioned during the movement of the pen tip on the paper, thereby realizing track recording. In the second mode, an auxiliary device such as an ultrasonic positioning device is required to realize track recording, and the structure is complicated. Contents of the invention ...
