/*
- C is a 3D vector that gives the location of the Center of projection of the left navcam camera as
it was positioned by the pan/tilt mast relative to rover frame when that image was acquired.
- A is a 3D vector that gives the Axis of that camera which is the direction in which it was pointed.
- The other two are the Horizontal and Vertical 3D vectors in the plane of the image sensor.
There is some nuance because the CAHV camera model doesn’t actually require A, H, and V to be orthonormal.
However, you can construct an orhonormal basis from them, see this code to do that:
https://github.com/NASA-AMMOS/VICAR/blob/8264ad382401a93224cbecb810796a0c0262d36b/vos/p2/sub/cahvor/cmod_cahv.c#L795
*/
/*
CAHV Camera Model
The CAHV camera model is equivalent to the standard
linear photogrammetric model for a pinhole camera. It
is useful for very small field of view cameras and as a
building block for more complex camera models. The
CAHV model consists of four 3-vectors: C, A, H, and
V. Vector C gives the location of the pinhole. Vector
A gives the camera axis, defined as the normal to the
image plane. Vector H encodes the horizontal axis of
the image plane (H’), the coordinate (Hc) of the image
column at the optical centre of the image plane, and the
horizontal focal length (Hs) of the camera, in pixels.
Vector V encodes corresponding information (V’, Vc,
Vs) in the vertical direction. The angle (theta) between
horizontal and vertical vectors H’ and V’ is about 90°.
Non-orthogonal H’ and V’ generally represent an
attempt to compensate for distortion that CAHV
vectors cannot directly model. Image dimensions are
supplied along with the CAHV model.
