    This study introduces a robust linear algorithm to calculate a rigid object's 3D motion from two views. It effectively handles noise and both zero and nonzero translations for improved motion estimation.

    Area of Science:

    • Computer Vision
    • Robotics
    • 3D Reconstruction

    Background:

    • Accurate 3D motion estimation is crucial for robotics and computer vision.
    • Existing methods often struggle with noisy data or specific translation cases.

    Purpose of the Study:

    • To develop a linear algorithm for estimating 3D rigid object rotation and translation.
    • To enhance robustness against noise and unify handling of zero and nonzero translation cases.

    Main Methods:

    • Utilizes point correspondences from two time-sequential perspective views.
    • Incorporates noise-combating measures.
    • Employs a unified approach for different translation scenarios.

    Main Results:

    • A linear algorithm for 3D motion estimation is presented.
