Measurement principles

The rc_reason_stack is a high-performance 3D-image-processing software stack that is used in combination with one or more 3D cameras such as Roboception’s 3D camera rc_visard or rc_viscore. Together, they provide rectified camera, disparity, confidence, and error images, which allow the viewed scene’s depth values along with their uncertainties to be computed.

In the following, the underlying measurement principles are explained in more detail.

• Stereo vision
• General information on 3D data
  • Computing disparity images
  • Computing depth images and point clouds
  • Confidence and error images
