A Fast and Dense 3D Scanning Technique Using Dual Pseudorandom Arrays and A Hole-filling Method

Acquisition of 3D data accurately and densely in real time using a low cost structured light system is still an ongoing topic among the computer vision community as it is hard to achieve all these features together. Among several techniques the pseudorandom array technique is widely used in real time 3D scene capturing as it tends to concentrate the entire coding scheme into a single pattern. But existing pseudorandom array decoding methods cannot decode a given symbol in real time when it has missing neighbors. As a solution to this problem we proposed a dual pseudorandom array encoding and decoding method and a hole-filling method which can improve the reconstruction accuracy and time. In this paper we compare our method with several other methods to show how our method captures 3D scenes quickly and densely.
