摘　　要：随着智能化设计技术的发展,手势识别技术在部分消费类产品上的应用已成为一大热点.笔者基于对手势识别装置展开了研究与设计:系统采用STM8单片机作为系统的控制核心,并采用FDC2214(高分辨率的电容式传感芯片)作为手势采集模块,实现感应式手势识别功能.制作8个大小不一的覆铜板安装在感应面板底部,采集手掌关键特征点电容值.利用一片FDC2214的4个通道检测8个特征点的电容变化情况.通过编写软件算法,比对训练数据和实时数据,然后通过LCD12864液晶显示屏显示比对结果,完成了手势识别功能.With the development of intelligent design technology,the application of gesture recognition technology in some consumer products has become a hot spot. This paper is based on the research and design of gesture recognition device. STM8 is used as the control core of the system and FDC2214 (high resolution capacitive sensing chip)is used as the gesture acquisition module to realize the inductive gesture recognition. 8 different size copper clad plates are made and then installed on the bottom of the sensor panel to collect the key feature point capacitance of the palm. The capacitance variation of 8 feature points is detected by using four channels of a FDC2214. The gesture recognition function is completed by writing a software algorithm,comparing the training data with the real-time data,and then displaying the comparison result by the LCD12864 liquid crystal display.
