Abstract

The children's electronic painting device includes two parts: a computer and a drawing board, wherein the computer includes a host, a display, a memory, etc., and the drawing board includes a liquid crystal display, a touch screen, a USB interface and a control circuit. Through the computer image matching algorithm software, a large number of object pictures stored in the memory can be compared with the plane coordinate information generated on the drawing board touch screen transmitted to the computer, and the object that is closest to the plane coordinate information can be selected. The picture of the object is displayed on the computer monitor alone, or displayed together with the content displayed on the computer monitor by the plane coordinate information. It can make children understand what objects are painted when they first learn to paint, enhance children's sense of accomplishment when painting, and continuously cultivate children's interest in painting.

Description

Children's electronic painting device

technical field

The invention relates to an electronic painting device, in particular to an electronic painting device suitable for children.

Background technique

Children like painting, and painting is conducive to cultivating children's imagination and innovation ability. When children practice painting on paper, it is inconvenient to modify the patterns drawn and requires a lot of paint, which increases the learning cost of beginners, so the drawing board came into being. The publication number is CN 101464752A, and the Chinese patent literature on June 24, 2009 provides a kind of electronic drawing board for computer drawing. The electronic drawing board adopts the same drawing operation mode as the existing common drawing board. The drawing board draws on the computer, and the drawn pattern can be displayed on the drawing board and the computer monitor simultaneously, but this document cannot directly allow children to perceive what they are painting for children who are just learning to paint, and it is easy for children to lose interest.

Contents of the invention

The present invention overcomes the deficiencies of the above-mentioned patent documents, and provides a children's electronic drawing device that can intelligently match the shape of children's drawings and then display objects of similar shapes that exist in reality, so as to enhance children's sense of achievement and interest.

To achieve the above object, the present invention adopts the following technical solutions:

Children's electronic painting device of the present invention comprises computer and two parts of drawing board, and wherein computer comprises host computer, display, memory etc., and drawing board comprises liquid crystal display screen, touch screen, USB interface and control circuit, and control circuit connects The plane coordinate information generated by the paintbrush or finger acting on the touch screen of the drawing board is transmitted to the computer and displayed on the computer monitor, and the control circuit also receives the content displayed on the computer monitor transmitted from the computer to the drawing board through the USB interface, and drives the drawing The content will be displayed on the panel LCD. Through the computer image matching algorithm software, a large number of object pictures stored in the memory can be compared with the plane coordinate information generated on the drawing board touch screen transmitted to the computer, and the object that is closest to the plane coordinate information can be selected. The picture of the object is displayed on the computer monitor alone, or displayed together with the content displayed on the computer monitor by the plane coordinate information.

In addition, there are a large number of object pictures stored in the computer memory, which can be replaced by temporarily grabbing cloud object pictures through computer software; and the computer can also be equipped with voice playback software, which can broadcast the name of the closest object picture.

Through the above-mentioned technical scheme, it is possible for children to understand what objects are painted when expressing their inner thoughts when they first learn to paint, so as to enhance children's sense of achievement when painting and continuously cultivate children's interest in painting.

Description of drawings

 Figure 1 is a logical structure diagram of a children's electronic painting device.

Detailed ways

As shown in Figure 1, the drawing board of the children's electronic painting device is provided with a control circuit with a USB interface, and is equipped with a liquid crystal display and a touch screen, and the touch screen and the liquid crystal display are bonded together and are located above the liquid crystal display. The logic function of the control circuit includes: converting the plane coordinate information generated by the brush or finger acting on the touch screen into data conforming to the USB interface specification and mouse signal format, and transmitting these data to the computer through the USB interface; The computer transmits and converts the content displayed on the computer display of the drawing board through the USB interface. These contents are actually binary data. Brightness, etc.) for conversion; use the converted data to drive the liquid crystal display of the drawing board for display.

The computer compares a large number of object pictures stored in the memory with the plane coordinate information generated on the touch screen transmitted to the computer through image matching software, and identifies the same name between two or more images through a certain matching algorithm. Point, that is, the search selection using matching criteria under the condition of primitive similarity. The selected object picture closest to the object reflected by the coordinate information is displayed on the computer monitor.

In addition, a large number of object pictures stored in the computer memory can be replaced by temporarily grabbing Internet cloud object pictures through computer software.

Further, the computer can be equipped with voice playback software, which can broadcast the name of the closest object picture, so that children can hear the name of the object they painted.

The above description is only an embodiment of the present invention, and is not intended to limit the present invention. For those skilled in the art, the present invention can be changed or modified by using existing software technology. For example, by setting the computer software, the objects stored by the computer are displayed on the display and the LCD screen of the drawing board in advance, so that children can compare and copy, and the results of the copying are image-matched according to the above-mentioned technical scheme, and the matching results are fed back to the children. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of the claims of the present invention.
