Abstract
Reverse engineering is typically carried out in a procedure which uses a special scanning device such as a 3D laser scanner. However, this typical procedure is not always suitable because of several reasons; for example, the object to be scanned needs to be suitable in the scanning stage of the device, which is not always possible; the scanning device is not always available because of the high cost of the introduction. Therefore, an alternative method for general users is expected. This study focuses on an image-based 3D shape reconstruction and measurement method using a typical digital camera. First, this paper describes the conventional reverse engineering method, followed by the image-based 3D shape reconstruction method proposed in this study. Then this paper shows the experimental results of measurements based on the reconstructed shape, and discusses the feasibility of the proposed method.
