Description
技术领域
本发明涉及人机交互领域,具体为基于光电感应的隔空手势识别方法及其控制装置。
背景技术
人机交互(Human-Computer
Interaction,简称HCI)变革是信息技术架构体系中感知层(或终端层)的重大技术变革。在科技与需求的双轮驱动下,人机交互技术高速发展,从早期的鼠标键盘发展到触摸感应、语音识别、图像识别、手势识别控制等新型人机交互设备,在用户体验方面得到明显改进。
手势交互是利用计算机图形学等技术识别人的肢体语言,并转化为命令来操作设备。手势交流是人的本能,在学会语言和文字之前,已经能用肢体语言与人交流。手势交互系统中主要组成部分:人、手势输入设备、手势分析识别和被操作终端设备对象。手势识别控制可应用于智能家居、智能穿戴、汽车电子、医疗设备、儿童教育、虚拟现实等领域。
手势识别方法可以分为基于数据手套和基于机器视觉的技术两类,使用数据手套的方式可以较为准确的感应和识别手部的细微动作,但是需要佩戴专门的数据手套,这种隔空手势识别方法使用麻烦,用户体验非常不好。而基于机器视觉进行手势动作识别的方法,因为要求对手部图像进行识别,所以要求手部距离图像传感器较近,以便获取足够识别处理的图像画面,但这种方法对于环境光照有比较高的要求。传统的手势动作识别过程需要手势建模、手势分割、手势分析等多个复杂步骤和过程。手势识别又可细分为静态手势识别和动态手势识别两类,静态手势对应手势模型参数空间里的一个点,而动态手势则对应手势模型空间里的一条轨迹,因此要涉及时间和空间关系。特别是对于动态手势而言,不同的用户在进行手势动作的时候会存在速率差异、轨迹差异、熟练程度的差异等,从而导致手势建模轨迹在时间轴上引起非线性波动,而这种非线性波动的消除是非常困难和复杂的,所以传统的基于二维图像的动态识别率普遍不够高。
因此,该技术有必要进行改进。
