A projection system with static pattern generating elements and a plurality of optical channels to the optical 3d - measurement

摘要

A projection system for the projection of at least one pattern on at least one object region in a measuring object located in comprises a first light source, a second light source, a first projector group and a second projector group. Both the first projector group as well as the second projector group comprises a plurality of two-dimensionally arranged projector units. Each projector unit comprises a static pattern generating element, a in a fluoroscopy direction in front of the static pattern generating element and a field lens, which is located in the fluoroscopy direction behind the static pattern generating member projection lens. Each projector unit is configured on from the first and second light source the light emitted and a respective partial patterns to act to project. The first projector group is of the first light source and the second projector group of the second light source are assigned. The first or second projector group is configured, a first and second plurality of partial patterns to generate data representative of a first or second resulting pattern result, and thus by means of a structuring unit for taken on their own the first or second resultant pattern within the measuring object region to produce. The first light source and the second light source can be controlled independently of each other, so that the first resulting pattern and the second resulting pattern at different times or with different levels of brightness can be projected.
