Embodiment Construction

[0031] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0032] One, the hardware structure based on the method of the present invention

[0033] The method in the present invention is based on a simple hardware structure. The touch screen module 101 sends the position coordinate signal to the central processing unit 102 through the data input interface, which outputs the result to the display screen module 103 or memory after calculation. In addition, a power supply system for power supply is also included.

[0034] Second, the method of measuring the size of the object

[0035] Such as figure 2 and image 3 shown.

[0036] Step 201, calculate the X-axis distance conversion coefficient C1 and the Y-axis distance conversion coefficient C2 according to the physical size of the effective working area of ​​the touch screen used and the coord...

Abstract

A method for measuring dimensions of objects by a touch screen includes steps of 1) calculating X-axis distance conversion coefficient C1 and Y-axis distance conversion coefficient C2, 2) using a touch pen to click two endpoints of a distance to be measured, 3) using the touch screen to transmit position coordinate signals (X1,Y1) and (X2,Y2) of the two endpoints to a central processing unit by electric conversion, 4) calculating actual physical dimensions D of the two endpoints by the central processing unit, and 5) outputting the actual physical dimensions D to an output device or a memory. Compared with the method for measuring dimensions of objects by the touch screen, a method for measuring angles of objects by the same includes using the touch pen to click three points of an angle to be measured according to the sequence of edge, angle and edge to calculate the included angle. The invention combines the digital processing technology and a digital display method, expands the application of the touch screen, and is convenient in use. Users can measure the dimensions and the angles of objects just by simple operations on the touch screen.

Description

technical field [0001] The invention relates to a method for measuring dimensions and angles based on a touch screen, which is suitable for various occasions where the touch screen is applied. Background technique [0002] With the development of consumer electronic products, touch screen technology is widely used in portable devices such as mobile phones, PDAs, electronic game consoles and MP3 / MP4 players. The working principle of the touch screen is to convert the position signal of the contact point into an electrical signal and then send it out in a certain data interface signal format. Therefore, a variety of applications have been derived, such as character handwriting input system, operation interface control, drawing function and so on. [0003] In the usual study, work and life, we often encounter some occasions that need to measure the size and angle of objects. Since rulers and protractors are generally not carried around, this brings great inconvenience to the ...
