Dynamic Projection Mapping for Vehicle Body Defect Identification

The patent replaces the manual visual inspection method with an automated vision inspection system using patterned lighting and image processing. The system captures images of the vehicle body surface, processes them through algorithms to detect defects, and automatically determines defect positions and types, thereby substituting human visual judgment with automated optical-mechanical systems to improve measurement precision while maintaining ease of operation through automated processing.

The patent introduces an intermediary projection system that maps defect information from the digital domain onto the physical vehicle body surface. The system projects defect positions, types, and severity levels directly onto the corresponding locations on the vehicle body, serving as a mediator between the monitor display and the actual defect locations. This allows operators to see defect information both on the monitor and projected on the vehicle surface, making identification more intuitive without losing information availability.

The patent employs a high-speed projector that serves multiple functions: it projects defect position information, defect type classification, severity levels, and real-time inspection results onto the vehicle body surface. This single device handles various information display requirements simultaneously, improving productivity through high-speed projection while managing device complexity by consolidating multiple display functions into one multi-functional projection system.
