Computing Euler angles from a rotation matrix

Computing Euler angles from a rotation document discusses a simple technique to find all possible Euler angles froma rotation matrix . Determination of Euler angles is sometimes a necessary stepin computer graphics, vision, robotics, and kinematics. However, the solutionmay or may not be matricesWe start off with the standard definition of the rotations about the three prin-ciple rotation of radians about thex-axis is defined asRx( ) = 1 000 cos sin 0 sin cos Similarly, a rotation of radians about they-axis is defined asRy( ) = cos 0 sin 01 0 sin 0 cos Finally, a rotation of radians about thez-axis is defined asRz( )

matrix is 1 or −1, which corresponds to θ= −π/2 or θ= π/2, respectively, and to cosθ= 0. When we try to solve for the possible values of ψand φusing the above technique, problems will occur, since the elements R 11, R 21, R 32, and R 33 will all be zero, …
