Bayesian methods offer a powerful framework for predicting and quantifying uncertainty in various practical systems. This study explores the application of Bayesian approaches in two distinct domains: structured light (SL) systems and pipeline corrosion analysis. In structured light systems, Bayesian method is utilized to build a complete coordinate uncertainty model from the root cause. Details on sources of aleatoric and epistemic uncertainty and its propagation to final reconstructed coordinates is discussed. Certain practical implementation issues and possible solutions are also discussed. Conversely, in pipeline corrosion analysis, Bayesian methodologies are employed to model uncertainty derived from acquired data. This application involves leveraging Bayesian inference to understand, model, and mitigate uncertainties arising from environmental factors and material behaviors. Through these two applications, Bayesian methods prove instrumental in navigating and managing uncertainties in practical systems, offering insights, predictions, and solutions vital for decision-making and system optimization.
