Determining positional information of an object in space

摘要: The technology disclosed relates to determining positional information of an object in a field view. In particular, it calculating distance the from reference such as sensor including scanning view by selectively illuminating directionally oriented light sources and measuring one or more differences property returning emitted reflected object. can be intensity phase difference light. It also finding region space. space with controllable illumination, illumination received for two points scanning, based part upon corresponding property.
