WebAug 17, 2024 · Model-based FDD approaches [ 1] that are based on developing a reference model or observer—using mathematics or physics law—are used to generate residual vectors, which describe the system health state to detect and isolate faults if a deviation from the expected values is observed. WebDec 22, 2009 · In this paper, the problem of how to estimate the distance between an infrared emitter diode (IRED) and a camera from pixel grey-level intensities is examined from a practical standpoint. Magnitudes that affect grey level intensity were defined and related to the zero frequency component from the FFT image. A general model was also …
