一种利用图像识别技术进行输入的键盘及方法 Keyboard and method for input using image recognition technology
技术领域： Technical field:
本发明涉及计算机领域，尤其涉及一种利用图像识别技术进行输 入的键盘及方法。 The present invention relates to the field of computers, and more particularly to a keyboard and method for inputting using image recognition technology.
背景技术- 键盘是用于信息录入的非常重要的输入设备之一，在我们当今的 生活中占有十分重要的位置， 但传统的键盘一方面很容易坏， 很怕进 水， 按键的缝隙中也容易落满灰尘， 而且不好清洁， 另一方面， 传统 键盘的结构复杂， 它不光需要复杂的电路， 还需要几十个按键， 既浪 费了大量的材料， 又使键盘的生产装配工艺变得比较复杂， 从而在一 定程度上增加了生产成本。 BACKGROUND OF THE INVENTION - A keyboard is one of the most important input devices for information entry, and it occupies a very important position in our daily life, but the traditional keyboard is very easy to break on the one hand, and is afraid of water, and the gap in the button. It is easy to be covered with dust, and it is not easy to clean. On the other hand, the traditional keyboard has a complicated structure. It requires not only complicated circuits but also dozens of buttons, which wastes a lot of materials and makes the keyboard assembly process become It is more complicated, which increases the production cost to some extent.
传统键盘的输入方法都是物理接触式的，既当按键被按下时通过 物理接触方式将电路板上的两个触点接通，相应的按键信号就被输入 到计算机， 这一方面使得键盘的结构变得复杂， 另一方面因为电路板 上的触点很容易氧化，使得按键的灵敏度随着时间的推移不断降低直 至消失， 从而影响整个键盘的使用。 The input method of the traditional keyboard is physical contact type, and when the button is pressed, the two contacts on the circuit board are connected by physical contact, and the corresponding button signal is input to the computer, which makes the keyboard The structure becomes complicated, and on the other hand, because the contacts on the board are easily oxidized, the sensitivity of the button is continuously reduced until it disappears over time, thereby affecting the use of the entire keyboard.
除了以上几点外， 现在我们也越来越多地使用因特网， 并且在很 多的地方都需要设置密码， 如电子邮箱、 网上银行、 网上购物等， 但 其中的密码却很容易泄露或被黑客破译，这些缺点在很大程度上限制 了我们使用网络的积极性， 也在一定程度上阻碍了经济的飞速发展。 In addition to the above points, we are now using the Internet more and more, and in many places we need to set passwords, such as e-mail, online banking, online shopping, etc., but the passwords are easy to leak or hacked. These shortcomings have largely restricted the enthusiasm of our use of the network, and to some extent hindered the rapid development of the economy.

具体实施方式： Detailed ways:
下面对照附图 1叙述具体实施方式：一种利用图像识别技术进行 输入的键盘是由透明面板 1、 面板支架 2和微型摄像头 3构成， 其特 征是： DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment will be described with reference to Fig. 1 : a keyboard for input using image recognition technology is composed of a transparent panel 1, a panel holder 2 and a micro camera 3, which are characterized by:
所述的透明面板 1由透明材料制成，上面印刷或蚀刻有按普通键 盘排列布局的按键， 透明面板 1的一端固定在面板支架 2上。 The transparent panel 1 is made of a transparent material, and is printed or etched with buttons arranged in a common keyboard arrangement, and one end of the transparent panel 1 is fixed to the panel holder 2.
所述的微型摄像头 3固定在面板支架 2上， 并且位于透明面板 1 的底部， 微型摄像头 3可以拍摄到透明面板 1上的所有按键， 微型摄 像头 3通过数据线可以与电脑相连。 The micro camera 3 is fixed on the panel holder 2 and located at the bottom of the transparent panel 1. The micro camera 3 can capture all the keys on the transparent panel 1, and the miniature camera 3 can be connected to the computer through the data line.
下面以一具体实例说明一种利用图像识别技术进行输入的方法： 当手指按在透明面板 1上的某一按键上时，手指与透明面板 1之 间会形成一个接触面，同时底部的微型摄像头 3会拍摄到该接触面的 图像并传给计算机，计算机软件一方面利用图像识别技术根据该接触 面的位置就能判断出所要输入的按键，另一方面也实时地计算出该接 触面的面积， 并与预先设定的一个默认面积值进行比较， 当接触面积 大于默认面积值时就表示按下该按键 （参见图 3 )， 计算机则输入所 按的按键，而当接触面积小于默认面积时就表示只是一般接触并不真 的按下按键 （参见图 4)， 计算机则不会输入任何信息， 从而防止误 操作， 该默认面积值的大小可根据不同人的情况进行调整， 当该默认 面积值设置得较小时，因为手指与透明面板 1之间的接触面积很容易 大于该默认面积值， 不需要用力按就会使接触面积大于该默认面积 值， 所以键盘的灵敏度就比较高， 当该默认面积值设置得较大时， 因 为手指与透明面板 1之间的接触面积很容易小于该默认面积值，手指 需要用力按才会使接触面积大于该默认面积值，所以键盘的灵敏度就
比较低。 A method for inputting by image recognition technology is described below with a specific example: When a finger is pressed on a certain button on the transparent panel 1, a contact surface is formed between the finger and the transparent panel 1, and the micro camera at the bottom is also formed. 3 The image of the contact surface is captured and transmitted to the computer. On the one hand, the computer software can determine the button to be input according to the position of the contact surface by image recognition technology, and calculate the area of the contact surface in real time. And compared with a preset default area value, when the contact area is larger than the default area value, it means that the button is pressed (see Fig. 3), the computer inputs the pressed button, and when the contact area is smaller than the default area It means that only the general contact does not really press the button (see Figure 4), the computer will not input any information, thus preventing misoperation, the default area value can be adjusted according to different people's situation, when the default area When the value is set smaller, since the contact area between the finger and the transparent panel 1 is easily larger than the default area value, If you need to press hard, the contact area is larger than the default area value, so the sensitivity of the keyboard is relatively high. When the default area value is set larger, the contact area between the finger and the transparent panel 1 is easily smaller than the default area. Value, the finger needs to press hard to make the contact area larger than the default area value, so the sensitivity of the keyboard is Relatively low.
下面以一具体实例说明本发明如何设置识别指紋密码： The following describes a specific example of how the invention sets the fingerprint identification password:
如设置密码为一字母 K时，一手指按在按键 K上，微型摄像头 3 拍摄到按在按键 K上的手指指紋并将其传给计算机，计算机则将字母 κ和手指的指紋信息一起设置为密码，解密时，一手指按在按键 K上， 微型摄像头 3拍摄到按在按键 K上的手指指紋并将其传给计算机，计 算机将按键 K和指紋的组合信息与以前所设置的密码信息进行比较， 如果相符则密码正确， 如果不相符那么所输入的密码则不正确。
If the setting password is a letter K, one finger is pressed on the button K, the micro camera 3 captures the finger fingerprint pressed on the button K and transmits it to the computer, and the computer sets the letter κ and the finger fingerprint information together as Password, when decrypting, one finger presses the button K, the micro camera 3 captures the finger fingerprint pressed on the button K and transmits it to the computer, and the computer combines the combination information of the button K and the fingerprint with the previously set password information. Compare, if the password matches, the password is correct. If it does not match, the password entered is incorrect.
