Rejection of spurious reflections in structured illumination range finders

摘要

Abstract: This paper describes techniques for two (or more) camera geometry structured illumination range finders that eliminates most spurious range values that arise from specular reflections from shiny (e.g. metallic) parts. The key observation is that specular reflections produce range values that depend on camera position. Hence, by using two cameras, several consistency tests can be applied that eliminate most spurious range data. This paper describes the constraints that underlie the tests and shows sample performance. !5
