On uniqueness in triangulation based pattern for structured light reconstruction

Abstract

In this paper, a new light pattern is proposed for three-dimensional reconstruction. This pattern has several interesting properties and is highly robust to deformation due to its topology. Moreover, the proposed pattern is based on triangulation meshes which allow us to construct arbitrarily a high number of unique key points. Furthermore, the graph permits to have information on connectivity between keys as it is a graph, and thus to work in areas where the key is not completely defined because of discontinuity in the surface of the scene.
