A Vision Based Audit Method and Tool that Compares a Systems Installation on a Production Aircraft to the Original Digital Mock-Up
- Event
- Content
- The work describes a concept application to aid a safety engineer to perform an audit of a production aircraft against safety driven installation requirements. The capability is achieved using the following steps:
- A)Image capture of a product and measurement of distances between datum points within the product with/without references to a planar surface
- B)A digital reconstruction of the fabricated product by using multiple captured images to reposition parts according to the actual model.
- C)The projection onto the 3D digital reconstruction of the safety related installation constraints, respecting the original intent of the constraints that are defined in the digital mock-up.
- D)Identification of the differences between the 3D reconstruction of the actual product and the design time digital mock up of the product
- E)Identification of the differences/non conformances that have a relevance to safety driven installation requirements with reference to the original safety requirement intent.
Step ‘A’ gives the safety engineer a means to perform measurements on a set of captured images of the equipment they are interested in. Steps ‘B’, ‘C’, ‘D’ and ‘E’ together give the safety engineer the ability to overlay a digital reconstruction that should be as true to the fabricated product as possible so that they can see how the product conforms/ or doesn't conform to the safety driven installation requirements. The work has produced a concept demonstrator that will be further developed in future work to address accuracy, workflow and process efficiency. - A)
