An Approach to the Geometrical Meaning of the Coordinate MSE with the Presentation of Mohr's Circle |
| |
| Abstract: | The paper describes the methods for drawing Mohr's circles by using variance and covariance data and the various methods for the presentation of the elements of error ellipse of point positions with Mohr's circle method. The geometrical meaning of this method is discussed. The results obtaimed from this method are clear and audio-visual. |
