Lições aprendidas do uso de videogrametria para inspeções de qualidade em armaduras de pré-fabricados de concreto

Resumen

The reinforcement assembly of precast concrete elements necessitates a high degree of precision. However, manual inspections can be both time-consuming and prone to errors. This study explores videogrammetry as a cost-effective alternative to laser scanning for generating geometric models that aid in quality inspections before concreting. A case study was conducted to evaluate video capture and image processing within a manufacturing setting. The findings revealed that filming reinforcements mounted on metallic supports significantly improved accuracy. Furthermore, optimal lighting, a frame rate of three frames per second, and high-quality settings enhanced both the detail and visualization of the models.
