    Mathematical Iteration for Alignment of 4 Points

    Points are located at certain object. Nominal points are the designed point dimensions, in the blue print, related to certain cartesian coordinate, or the dimensions of these points as specified in the CAD drawing. Measured points are the actual measured locations or dimensions in the real...

    Mathematical Iteration for Alignment of 4 Points

    What is the mathematical equation or algorithm for alignment of four points in cartesian coordinates (X & Y). Say, we have 4 nominal points (Xn & Yn), and another 4 measured points (Xm & Ym)?. After alignment, what are the new locations of the measured points (Xmn & Ymn)?.

    Determining the Point and Angle of Rotation

    The case is that body (box) is set, initially, randomly on a fixture where the cartesian coordinates (x, y, z) of certain points are recorded. According to these readings the final reading (the new position and orientation) are designed. To Achieve this goal (final position and orientation), a...

    Determining the Point and Angle of Rotation

    Yes, old and new point coordinates (x, y, z) are known. My problem is how to map or to relate old and new data in order to extract the point and angles of rotation and translation.

    Determining the Point and Angle of Rotation

    I've an irregular box that is set on a fixture. The fixture is capable to translate and rotate the box. The original position of the box is known, by probes located at each side. If the box is translated and rotated to a new known location, with same probes. How do I determine the point and the...
