Abstract In this study, we developed an augmented reality (AR) Android app that helps assembly work of an automobile valve-body and detects assembly mistakes in real time, and confirmed its usefulness through testing. To show the shapes of the assembly parts of the valve-body, the assembly positions and orders, and the assembling situation, AR contents are produced and projected on the valve body image of the smart-phone screen, and then displayed to the operator. In order to project the contents on the correct positions of the valve-body, a feature-data set is extracted from a 2D image of the valve-body by using Vuforia tool. Then the real time valve-body pose is tracked based on the set. By using the 2D image, easily acquired with an ordinary camera, the procedure and time are reduced compared with the case of using the 3D image, and it is confirmed that the 2D image can be applied without difficulty to the tracking of relatively flat objects like the valve-body. In order to confirm whether the parts are assembled in order at correct positions on the valve-body, after painting a specific color on a spot of a part, it is judged whether or not the part is assembled by an image processing which periodically discriminates the color of the area to be assembled.
