Abstract:Testability verification test is a test conducted to confirm whether the testability of equipment meets design requirements, which plays an important role in improving the level of testability of equipment. However, there are often problems such as equipment damage, test point limitations, and high technical requirements for operators in verification tests. Therefore, an application study of equipment testability verification test based on Augmented Reality (AR) technology was proposed, Using AR technology to model and simulate equipment, virtual accessories and real equipment are matched to each other, transforming planar knowledge into visualized three-dimensional knowledge that combines virtual with reality, enhancing the visibility, accessibility, and operability of verification tests, guiding operators to complete testability verification tests, improving the efficiency and correctness of verification tests, and using a certain type of unmanned aerial vehicle as the test verification object, It is proved that augmented reality technology can provide effective decision-making support for the implementation of equipment testability design improvement.
