In the manufacturing industry, Augmented Reality (AR) has shown significant potential in enhancing operators’ capabilities while performing inspection and assembly activities. However, the augmented visualization of virtual models on physical components can present challenges and potential misunderstandings, as the visualization mode greatly influences the perception of components and the amount of information received. This study investigates the impact of rendering techniques on user performance during industrial assembly inspection tasks. In particular, a set of rendering techniques, suitable for industrial AR applications, have been selected and implemented through a dedicated AR tool. The selected AR rendering techniques have been compared, in terms of qualitative and quantitative metrics, in order to test their efficiency and effectiveness for industrial assembly inspection activities. 17 domain experts and 33 representative users have been involved in the experimental study which outcomes reveal that the rendering techniques play a significant role in assisting operators for identifying design discrepancies in industrial products. Furthermore, a correlation has been observed between the two AR rendering techniques best suited to support industrial inspection activities and the types of assembly errors detected.

在制造业中，增强现实 (AR) 在增强操作员执行检查和装配活动的能力方面显示出巨大潜力。然而，物理组件上虚拟模型的增强可视化可能会带来挑战和潜在的误解，因为可视化模式极大地影响组件的感知和接收的信息量。本研究调查了工业装配检测任务中渲染技术对用户性能的影响。特别是，选择了一套适合工业AR应用的渲染技术，并通过专用的AR工具实现。所选的 AR 渲染技术在定性和定量指标方面进行了比较，以测试其在工业装配检测活动中的效率和有效性。17 位领域专家和 33 位代表性用户参与了实验研究，结果表明渲染技术在帮助操作员识别工业产品的设计差异方面发挥着重要作用。此外，我们还观察到最适合支持工业检测活动的两种 AR 渲染技术与检测到的装配错误类型之间存在相关性。
