dc.description.abstractThis bachelor thesis introduces an integrated solution for improving the automotive test cubing process by using AR tracking systems alongside an articulated mechanical mounting solution for marker placement. This project is organized into two distinct phases, which solve important issues with current prototyping and quality assurance processes. The initial work examines optimizing reference marker models (RMMs) for application with AR-based visual inspections. By iterative design and experimental testing, a novel approach, referred to as 'pattern synergy,' was created. This approach involves the superimposition of two-dimensional patterns for generating a spatially consistent three dimensional marker system. These upgraded markers contribute noticeable advances for recognition stability, tracking accuracy, and alignment consistency when overlaid with CAD data, especially for cases with dynamic lights or occlusions. Deployment of such markers was tested within real cubing environments and showed measurable process efficiency and digital overlay accuracy gains. In spite of all of these improvements, a primary limitation still existed—physical accessibility to some surfaces of the test cube, especially internal or partially blocked areas that are directly inaccessible by virtue of the build sequence. A mechanical solution for this is presented by the second phase of the thesis—a modular articulation beam arm designed for marker placement within previously inaccessible areas. The development made use of CAD and structural analysis, optimising for stiffness, angular accuracy, and repeat ability. This consists of two hollow aluminum beams connected by a precision rotational joint with 45° articulation capability over all four directions, and is mounted upon a rigid aluminum base which can be screwed on underneath or along a side. Particular emphasis has been given to deflection analysis for a loaded arm, joint lock schematics, and torque strength, so that the arm remains within a strict 0.2 mm tolerance for marker alignment. By integrating digital augmentation with accurate mechanical design, this thesis presents a new paradigm for taking AR-based inspection tools further into the automotive prototyping process and testing.
