内容記述タイプ | Other | |||||
内容記述 | In this paper, a theory which recovers 2 rotational angles and the radius of a circle using an image by supposing orthographic projection is described. Although any object having any position and pose in the 3-dimensional space has 6 degrees of freedom, our subject becomes the recovery problem of 2 rotational angles of a circle under such a supposition. First, we certify that an image of a circle is an ellipse either by perspective projection or by orthographic projection. Second, the equations for calculating the normal vector of a circle are derived using an image which is supposed to be projected orthographically. Then 2 rotational angles and the radius of a circle are calculated using the normal vector. Last, several experiments are simulated and the recovering accuracy is examined. | |||||
