Abstract
A talking pen is the evolutional way of learning especially for children because it is fun and interactive. Commercial talking pen use a small infrared camera to capture the hidden dot patterns that hidden around a book's page. Specific sounds are generated according to the location of the pen on the pages. This image processing for recognition technique is complex and need calculation power because it had to calculate relative location and orientation of dots in a group. Although, the talking pen is successful product but it is not flexible to add new pattern or uses different set of patterns. In this research, the new approach for hidden dot pattern recognition is proposed. Convolutional neural networks or CNNs is selected as the recognition software. The system is built on Raspberry Pi Zero W hardware with Raspbian operating system and TensorFlow platform. MobileNet is used in the research since it small and effective for limited resources platform. MobileNet is trained by using the infrared images that captured by infrared camera module that connected to Raspberry Pi. Result shows that the accuracy of the proposed method is good enough and the response is fast enough to be implemented into the real-time commercial product and has ability to expand to any other kind of patterns without limit because the learned network can be updated easily without alter recognition software.
会说话的笔是一种进化的学习方式,尤其是对孩子来说,因为它很有趣,而且是互动的。商业有声笔使用一个小型红外摄像机来捕捉隐藏在书页周围的隐藏点图案。根据笔在页面上的位置产生特定的声音。这种识别技术的图像处理复杂,需要计算一组点的相对位置和方向,需要计算能力。虽然说话笔是成功的产品,但它不能灵活地添加新的图案或使用不同的图案集。本研究提出了一种新的隐点模式识别方法。选择卷积神经网络(cnn)作为识别软件。该系统基于Raspberry Pi Zero W硬件,采用Raspbian操作系统和TensorFlow平台。由于MobileNet在资源有限的平台上体积小、效果好,所以在研究中使用了MobileNet。MobileNet通过使用连接到树莓派的红外相机模块捕获的红外图像进行训练。结果表明,该方法具有较好的准确率和较快的响应速度,可以应用到实时商业产品中,并且由于学习到的网络可以在不改变识别软件的情况下轻松更新,因此可以无限制地扩展到任何其他类型的模式。
