非接触式婴幼儿身高测量系统设计

Design of non-contact measurement system for infant height

以Xilinx公司的PYNQ-Z2主控板为核心,结合人体关键骨骼点检测和双目视觉定位原理,设计实现了一套非接触式婴幼儿身高测量系统。利用深度神经网络LightweightOpenPose,实现人体关键骨骼点提取;利用双目视觉定位,获取人体关键骨骼点三维坐标信息,从而计算出婴幼儿身高。该系统不仅可以实现非接触式测量,还可以在不同姿态下完成准确测量,方便卫生,简洁可靠,可广泛应用于医疗和居家等领域。

Taking the PYNQ-Z2 main control panel of Xilinx corporation as the core, combined with the principle of human skeleton point testing and binocular vision, a non-contact measurement system of infants’ height is designed and realized. The deep neural network Lightweight OpenPose is used to realize the extraction of the key bone points of human body. The three-dimensional coordinate information of key bone points of human body was obtained, and the height of infants was calculated by using binocular vision positioning. The system can not only realize non-contact measurement, but also complete accurate measurement in different postures, which is convenient, sanitary, simple and reliable, and can be widely used in medical and home fields.
