Abstract

This paper aims to develop a 3D panoramic sensor with a catadioptric imaging system. First, the fringe pattern is designed in a polar coordinate system to match the dimensions of a hyperbolic mirror. Second, a variable-frequency fringe pattern is proposed to obtain the constant-frequency reconstruction in real space. Experiments are conducted to verify system accuracy and feasibility, and the experimental results show the effectiveness of the proposed 3D panoramic sensor.
