AR-based Accessibility Verification Method for Smart Manufacturing System with Human Motion Capture

With the development of industrial production towards personalization and intelligence, process validation of manufacturability has become a complex and time-consuming problem in manufacturing system. Smart manufacturing requires manufacturing system to have the ability of rapid response to various product designs. However, there is an obvious time span between product design and accessibility verification process. Augmented reality (AR) constructs an environment of virtual reality integration, which brings people intuitive visual feeling and natural interaction feedback. It can be easily applied to the early stage of product accessibility verification. This paper presents a digital human assisted accessibility verification system based on AR, which can perform accessibility verification in the product design stage. In this system, augmented reality glasses are used to realize the natural interaction between human and product 3D model, and a motion capture device is used to realize the superposition of digital human and operators. This paper expounds the above methods and related devices in detail, verifies the feasibility of this system through an industrial example, and shows its application potential in smart manufacturing system.
