PROBLEM TO BE SOLVED: To flexibly determine a rotating condition of an object body regardless of a rotating surface without complicating a sensor structure.SOLUTION: A rotation condition calculation device 1 includes: a data acquisition part 21 for temporally and continuously acquiring three-axis angular speed data from a three-axis angular speed sensor 10; a data pre-processing part 22 for temporally and continuously calculating the three-axis angular data based on the three-angular speed data; a normal line vector candidate calculation part 23 for temporally and continuously calculating a position vector of an object body based on the three-axis angular data and calculating the normal line vector candidate of a rotation surface by calculating the normal line vector of a flat surface along the position vector by approximate calculation; and a normal line vector calculation part 24 for calculating a representative normal line vector by executing analysis processing with the normal line vector candidate of an object and calculating a degree of variation with reference to the representative normal line vector of the normal line vector candidate, and generating information relating to the rotation condition of the object body based on the degree of variation.SELECTED DRAWING: Figure 1 |
