A new image measurement method for wheel hub

Abstract

Sizes of wheel hub are difficult to be measured directly, and a new image measurement method for the wheel hub is proposed in this paper. After images of wheel hub are captured and dealt with, useful information of wheel hub is extracted. Then the 3D-model of wheel hub which is composed of 4 circles is rebuilt accurately. Therefore, inner and outer sizes of wheel hub are measured indirectly. Some experiments have been done by the new method. The experiment results show that this new method is very effective and accurate sizes of wheel hub are obtained.
