Software program caliber is a generalised assertion tough to agree or disagree with until eventually an actual definition of the concept that of "Software caliber" is reached when it comes to measurable amounts. regrettably, for the software program know-how the elemental query of: • what to degree; • easy methods to degree; • while to degree; • the best way to care for the information acquired are nonetheless unanswered and also are heavily dependant at the box of software.

The purpose of our active calibration is to correct the left and right angle of the eye axes to reduce the depth error. The basics of this method is transforming each image plane to be orthogonal to each eye axis. , the intrinsic parameters A and extrinsic parameters: Re , Te , Rc and Tc are known. The intrinsic parameters can be calibrated by using various algorithms in which Zhang’s method  is widely used. Also, the rotation matrices Rxt (ϕ) and Ryt (θ) are known. In real applications, these two parameters can be read from motor encoders.
The coordinatec of C is given by: ˆ c = −h−1 h (19) H = [h |−hc ] (20) therefore, we can write H as: then, we have: ⎡ ⎤ ⎡ ⎤ xw u ⎢ yw ⎥ ⎥ λ ⎣ v ⎦ = [h| − hc] ⎢ ⎣ zw ⎦ 1 1 (21) Consequently, the transformation from homogeneous world coordinates to homogeneous image coordinates converts to a transformation from homogeneous image coordinates to world coordinates: Pw = c + λh−1 P˜im (22) The main point behind active calibration is the generation of new left and right projection matrices according to time t.
