This class holds feature correspondence information for a particular feature
(point, line segment, circle, etc.).
A Cog3DCrsp2D3D is a data holder class that expresses how a 2D feature(s)
(found in the acquired image from a particular
camera) corresponds to a 3D feature of the 3D model.
The feature correspondence information consists of:
- The index of the camera from which the image was acquired;
- The index of the found part instance in the acquired image. Each part found in an acquired image from camera C, must have a unique index. Each part found in an acquired image from camera C+1, must also have a unique index, however there is no requirement for the part indices across the acquired images to match.
- An Object representing the found 2D feature e.g. Cog3DVect2 or an Object representing a collection of found 2D features e.g. Cog3DVect2Collection from the acquired image. The 2D feature's pose must be in Raw2D space of the acquired image.
- The index of the 3D model feature within the 3D model feature collection
- The subfeature type (Cog3DSubfeatureConstants) within the 3D feature that corresponds to the found 2D feature(s).
