Abstract(in English) | Tooth mobility is measured to characterize periodontal tissues. Its 3-dimensional features,however,have yet to be clarified.To detect these in three-dimensions,we have been developing a 6- degree-of-freedom displacement meter,DDM6, 1,using a range finder. This paper presents a practical calibration technique for this.The equipment comprises two elements,a reference devise installing 6 range finders and a moving polyhedron with 6 planar reflecting surfaces,each facing the range finder.The distance-output relationship of the sensor is represented by a polynomial in consideration of its non-linearity.In the calibration,the moving part is translated into different positions,using a 3-D pulse stage.At all positions,translation vector and sensor outputs are recorded.Since the orientation of the moving part relative to the reference devise is not provided precisely,we developed a technique capable of estimating both sensor parameters and the orientation from calibration data.This technique was verified to provide valid estimates,through computer simulation. |
