Abstract

The object distance is an important parameter for image recognition and robot 3D view. This paper presents a novel method of image pixel multidither passive ranging. Based on Fourier transform theory of lens imaging, we derive the mathematical model of ranging, obtain the ranging error equation using lens equation, and analyze the effect of spectrum width and the limit for demodulation. It shows that the performance of this method has high sensitivity and precise measurement.
