System and method for realizing three-dimensional drawing based on touch terminal

Abstract

The invention discloses a system and method for realizing three-dimensional drawing based on a touch terminal. The system comprises a touch screen, a touch signal processing and distance measuring locating module, a central processor, a DSP (Digital Signal Processor) processing module, an FPGA (Field Programmable Gate Array) module, a display drive module and a display screen. The method comprises the steps of: detecting a distance between a hand and the touch screen and an inclined angle between the hand and the vertical direction of the touch screen according to the change of a signal generated when the hand leaves from the touch screen by the touch signal processing and distance measuring locating module; then sending a three-dimensional drawing instruction to the DSP module according to a processing result of the touch signal processing and distance measuring locating module by the central processor; and then performing filtering treatment, threshold segmentation treatment, image quantity calculation and image parameter confirming and displaying treatment on a plane image by the DSP processing module, and driving the display screen by the display drive module to display a three-dimensional image. The aim of converting the plane image into the corresponding three-dimensional image according to a human gesture is achieved, and a new experience is brought to users.

Description

technical field [0001] The present invention relates to the technical field of touch control of mobile terminals, in particular to a system and method for realizing three-dimensional drawing based on a touch terminal. Background technique [0002] With the rapid development of electronic technology, touch devices are more and more popular with consumers. Because touch technology has brought great convenience to people, mobile phones, remote controls, TVs, large-scale electronic production equipment, cash machines, automatic Touch technology has been widely used in ticket vending machines and the like. [0003] At present, the touch control method of the touch display has been developed from a simple single-point touch to a multi-touch, but the user's demand for the touch method is still not fully satisfied, and many functions still need multiple touches to complete. . Large-screen touch control display devices are more and more widely used in the field of education, drawin...
