Sensor for Distance Estimation Using FFT of Images

Sensor for Distance Estimation Using FFT of Images

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 FF...
