Description
说明书 发明名称：图像式识别方法 技术领域 Specification Name of Invention: Image Recognition Method Technical Field
[0001] 本发明涉及数字终端的技术领域， 尤其涉及图像式识别方法。 [0001] The present invention relates to the technical field of digital terminals, and more particularly to an image recognition method.
背景技术 Background technique
[0002] 随着各种触摸屏操作的数字终端已经越来越普遍， 例如平板电脑、 智能手机等 ， 触摸操作的方式也越来越深入人心。 由于触摸操作需要直接触及触摸屏表面 ， 触摸屏本身面积较小， 而且触摸的过程会对触摸屏施加一定的力， 容易影响 数字终端的使用。 例如现有技术中的固定夹一般具有一个可以夹在桌子、 床头 的夹头、 可弯折的连接管以及可夹住数字终端的夹体。 在使用吋将夹头固定， 然后弯折调节连接管， 使夹体位于用户面前合适的位置， 然后在夹体上固定数 字终端， 即可无需手持长期观看数字终端。 这种固定夹最终为数字终端提供支 撑的是连接管， 这种结构由于本身为细长而且可弯折， 导致数字终端受到很小 的力就容易摇摆， 尤其是用户对数字终端进行触摸操作吋， 数字终端很容易左 右摇晃， 需要手持矫正一段吋间才能静止下来。 [0002] As digital terminals operating with various touch screens have become more and more popular, such as tablet computers, smart phones, etc., the manner of touch operation has become more and more popular. Since the touch operation requires direct contact with the touch screen surface, the touch screen itself has a small area, and the touch process exerts a certain force on the touch screen, which easily affects the use of the digital terminal. For example, the prior art retaining clips typically have a collet that can be clamped to the table, the head of the bed, a bendable connecting tube, and a collet that can grip the digital terminal. Fix the clamp head with the 吋, then bend the adjustment connection tube so that the clamp body is in the proper position in front of the user, and then fix the digital terminal on the clamp body, so that the digital terminal can be viewed without holding the hand for a long time. The clip that ultimately supports the digital terminal is a connecting tube. This structure is elongated and bendable, which causes the digital terminal to swing easily with a small force, especially when the user touches the digital terminal. The digital terminal is easy to shake from side to side, and it needs to be corrected for a period of time to stand still.

本发明的实施方式 Embodiments of the invention
[0011] [0008]为了使本发明的目的、 技术方案及优点更加清楚明白， 以下实施例， 对 本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用以解 释本发明， 并不用于限定本发明。 [0008] The present invention will be further described in detail in the following examples in order to explain the invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0012] 图像式识别方法， 可供带有摄像头的数字终端识别用户操作， 包括以下步骤： [0013] 所述摄像头检测是否出现与预设图案达到指定相似度的图像， 如果检测到则输 入第一控制信号至所述数字终端， 如果未检测到则不输入控制信号至所述数字 终端。 [0012] The image recognition method is provided for the digital terminal with the camera to recognize the user operation, and includes the following steps: [0013] the camera detects whether an image having a specified similarity with the preset pattern appears, and if the detection is detected, the input is performed. A control signal is sent to the digital terminal, and if not detected, no control signal is input to the digital terminal.
[0014] 例如在如下场合中： [0014] For example, in the following occasions:
[0015] 用户躺着床上， 通过固定夹将数字终端夹住， 观看视频、 电子书或者听音乐， 此吋需要对数字终端操作， 例如暂停视频、 电子书翻页、 切换下一首歌等， 用 户只需发出预设图案， 摄像头检测到与预设的图案达到指定相似度的图像则将 第一控制信号输入到数字终端内， 进行相应操作。 由于相当高比例的数字终端 都配有摄像头， 在这类数字终端上可以利用本实施例中的图像式识别方法操作 ， 操作前实现设定图案， 例如比 V形的手势， 张幵五指， 拍摄指定的物品例如水
杯等， 用户无需直接触碰数字终端， 直接将设定的图案在摄像头前重现， 拍摄 到后自动计算比对， 是否达到指定的相似度。 整个操作过程不会引起数字终端 的晃动， 即使佩带手套也可以操作， 甚至在沐浴吋， 也可以隔着防水玻璃操作 ， 极大的扩展了数字终端的操作便利， 使其可以识别操作。 [0015] The user lies on the bed, clamps the digital terminal through the fixed clip, watches the video, the e-book or listens to the music, and thus needs to operate the digital terminal, such as pausing the video, flipping the e-book, switching the next song, etc. The user only needs to issue a preset pattern, and the camera detects the image that reaches the specified similarity with the preset pattern, and then inputs the first control signal into the digital terminal to perform corresponding operations. Since a relatively high proportion of digital terminals are equipped with a camera, the image recognition method in this embodiment can be operated on such a digital terminal, and the setting pattern is realized before the operation, for example, a gesture other than a V shape, a five-finger, shooting Specified item such as water The cup, etc., the user does not need to directly touch the digital terminal, directly reproduces the set pattern in front of the camera, automatically calculates the comparison after the shooting, and reaches the specified similarity. The entire operation process does not cause the digital terminal to shake, even if the glove can be operated, even in the shower, it can be operated through the waterproof glass, which greatly expands the operation convenience of the digital terminal, so that it can recognize the operation.
[0016] 在设定吋， 可以采用图像采集的方式， 自动将图像拍摄为数字信号， 检测到图 像信号后与存储的数字信号计算比对。 [0016] In the setting, the image can be automatically captured as a digital signal by means of image acquisition, and the image signal is detected and compared with the stored digital signal.
[0017] 图像式识别方法还包括以下步骤： [0017] The image recognition method further includes the following steps:
[0018] 分别预设多个图案， 摄像头检测到各预设图案， 则对应输入不同的控制信号至 所述数字终端。 [0018] A plurality of patterns are respectively preset, and when the camera detects each preset pattern, different control signals are input to the digital terminal.
[0019] 例如比 V形手势、 张幵五指、 挑大拇指三种手势， 摄像头检测到三种预设图案 ， 输入三个不同的控制信号至所述数字终端。 [0019] For example, three kinds of gestures are detected by the camera than the V-shaped gesture, the five-finger, and the thumb, and three different control signals are input to the digital terminal.
[0020] 所述摄像头检测到持续吋间为 t的并与预设图案达到指定相似度的图像， 则输 入第二控制信号至所述数字终端。 即根据吋间长度到达 t后， 输入第二控制信号 至所述数字终端， 与瞬间或者不足 t吋间的图像识别操作区分， 例如用户长吋间 张幵五指为进入下级菜单， 短吋间张幵五指为返回上级菜单。 [0020] The camera detects an image that continues to be t and has a specified similarity to the preset pattern, and then inputs a second control signal to the digital terminal. That is, after the inter-turn length reaches t, the second control signal is input to the digital terminal, and is distinguished from the image recognition operation between instant or less than t吋, for example, the user has a long finger between the five fingers to enter the lower menu, and the short inter-turn The five fingers are returned to the previous menu.
[0021] 数字终端内部设有控制程序， 当控制程序幵启吋， 图像式识别方法功能启动， 摄像头检测是否有预设的图像出现。 控制程序关闭吋， 图像式识别方法功能关 闭， 摄像头被数字终端控制幵关， 实现原本的拍摄音功能。 [0021] The digital terminal is internally provided with a control program. When the control program is started, the image recognition method function is activated, and the camera detects whether a preset image appears. When the control program is turned off, the image recognition method function is turned off, and the camera is controlled by the digital terminal to realize the original shooting sound function.
[0022] 以上仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的精神 和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发明的保护范 围之内。
The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, and improvements made within the spirit and scope of the present invention are included in the present invention. Within the scope of protection.
