This master's thesis deals with the application of Projective Geometric Algebra (PGA) to solve problems in three-dimensional kinematics and computer vision. The first part of the thesis is dedicated to theoretical foundations, demonstrating how the transition from standard geometric algebra to its projective extension enables a unified and elegant description of both translations and rotations using a universal two-sided product and motors. On a theoretical application level, the thesis presents the use of this mathematical framework for the geometric formulation of 3D scene reconstruction from a binocular camera system. The practical contribution lies in the application of Gram-Schmidt orthogonalization to construct a stable local reference basis. The functionality of this algebraic approach is verified in the Python programming language through the analysis of real spatial data recording the motion of a parachutist. The results demonstrate that PGA represents a highly robust mathematical tool for the analysis of dynamics and spatial orientation, with direct applications in the fields of virtual reality.
