The conjugated distances u, v and the focal length f are related by the lens conjugate equation (Ray 1984) as 1/u + 1/v = 1/f, by which the image distance can be derived from v = uf/ u − f), leading to the actual length of the principal distance.
However, the principal distance (c) exactly equals the focal length (f) when and only when focused at infinity, namely, c ≈ f; otherwise the principal distance should be corrected to improve the measurement accuracy.
This explains why the principal distance (c) can be approximated as the focal length of the camera lens (f).
In principal, either the length of the fragment or the distance between the mutation and the CORE-GS insertion site (termed the "mutation-to-insert" distance) could influence incorporation frequency.
Her principal dimensions are: Length over all, 882ft.
The internal camera parameters (focal length, principal point and lens distortion) and the external camera parameters (baseline and relative orientation between cameras, lever-arms and bore-sight angles with respect to the inertial measurement unit (IMU)) are required to relate the image coordinates with the object coordinates in the scene.

From the NIS inpatient stays were excluded in which data on sex, admission type, disposition of patient (discharge status), principal diagnosis, and length of stay were missing.
The principal outcome is "length of delay 3 correct," the longest delay at which the child retrieves the toy correctly three times in a row.
Where (x 0, y 0), f and ( left({v}_{x_i},{v}_{y_i}right) ) are the principal point, the focal length and the measurement noises, respectively.
We derive the relation between the contour deformation and the 3D motion components, assuming time-varying focal length and principal point.
