Triangulation can also refer to the accurate surveying of systems of very large triangles, called triangulation networks. In image based structure refinement, on the other hand, 3D structure is refined using a number of additional views and an image based cost metric.

  • RGB-D sensors can thus produce depth maps whose noise is local and almost Gaussian. "[Show abstract] [Hide abstract] ABSTRACT: In this work, image based estimation methods, also known as direct methods,
  • The model does not include, for example, geometric distortions or blurring of unfocused objects caused by lenses and finite sized apertures.
  • Image based estimation methods are particularly useful in conditions where the Lambertian assumption holds, and the 3D points have constant color despite viewing angle.
  • A statistical error analysis is provided to help understand how the performance of a given stereo system relies on the system parameters.

In photometric camera pose estimation, 3D rotation and translation parameters are estimated by minimizing a sequence of image based cost functions, which are non-linear due to perspective projection and lens distortion.
