Further, the table body includes a table A and a table B that link to each other through the hinge, table B both sides are connected on corresponding lifting support through the hydraulic stem respectively be equipped with the spacer pin on the hydraulic stem.

Furthermore, a plurality of limiting rods are arranged on the table board B, a hand-drawing board is placed on the limiting rods, and a pen groove is formed in one side of the hand-drawing board.

Further, a light support is arranged on the other side of the table body, an LED lamp is mounted at the end of the light support, and a switch is arranged on the LED lamp.

Furthermore, the camera support a, the camera support b and the lamplight support are universal supports.

Furthermore, a lower hanging plate is arranged between the lifting brackets.

Furthermore, the table body can be lifted by 62-126cm through the lifting support.

Furthermore, a switch a is arranged on the panoramic camera, and a switch b is arranged on the automatic zooming camera.

As a further step, an infrared sensor is arranged in the camera capable of automatically zooming and used for recognizing the temperature of the hand, and the infrared sensor is matched with an image recognition technology to lock the position of the hand, so that the lens is always focused on the hand drawing board.

As a further step, the camera a and the camera B are connected with the microcontroller through the video sampling auxiliary circuit, and the microcontroller is further connected with the photoresistor and the LED lamp through the dimming controller respectively.

Compared with the prior art, the technical scheme adopted by the invention has the advantages that: the drawing table is foldable, convenient to carry and space-saving; the panoramic camera arranged above the teaching video can record the drawing process and the drawing progress, so that a viewer can watch the teaching video more clearly and watch the teaching video repeatedly to deepen memory; the camera capable of automatically zooming can enable the lens to be always focused on the hand-drawing board and track the action of the hand; the wall-mounted display has two camera viewing angles, so that a user can conveniently adjust the recording angle; the light source above the desktop automatically blurs and adjusts the brightness along with the change of the drawing environment.

Detailed Description

The embodiments of the present invention are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.

Example 1

This embodiment provides a drawing table with hand tracking technique and panorama video recording function, and this drawing table bottom is the base, and the table body on the base plays holistic supporting role. The lifting adjusting button is positioned on the lifting bracket between the table body and the base. The height of the lifting bracket can be adjusted to be 62-126cm by the lifting adjusting button. The table body comprises a table board A and a table board B which are connected through hinges, and the table board A is connected with the upper support and the upper hanging plate. The baffle is located the link plate top through both sides upper bracket, has the function of accomodating, and camera support a is still being connected to its middle part, avoids the influence of shadow, the panorama camera video of being convenient for. The wall-mounted display is 12.9 inches in screen size and is hung in front of the upper hanging plate. The camera support b is positioned on the table board A, and the camera capable of automatically zooming can track the movement of the hand of a user and follow the video in real time. The position and the angle can be adjusted left and right according to the habit of the user. The pen groove is embedded on the desk B, so that the pen is not easy to lose after drawing.
