Object contour reconstruction based on single camera and special geometry relation of mirror surfaces

Abstract

We use four plane mirrors with their sides perpendicular to each other, use a single camera to take a shot, and by analyzing the mirror images in parallel mirrors, it can realize the contour collection of objects. In this paper, the imaging principle of single camera combined with single plane mirror and a pair of parallel plane mirrors is analyzed and compared, and the image center coordinate of pixel depth is eliminated, and multi-facet mirror are used to eliminate the error point. The experimental results show that the contour of the model can also be obtained without using the image center, and with less errors points on reconstructed surface.
