Data Fusion Method for Online Detection Based on Contour of Parts

Abstract

In this article, a method of data fusion based on contour of parts is proposed for multi-factors measurement. Contour of the parts is used as a reference to fusing data because it is more sensitive to the angular changes than other parts and the relative positions between the contour and other individual part are fixed. This method not only is a reference to fuse data from multi-sensors, but also could apply feedback control for the measurement system. A key part of automotive transmission named splined hub has been used in the verification experiment in which the principle and structure of the measurement system is introduced.
