Modeling of automobile part based on CCD camera system

This paper discusses the acquisition method of digital image with CCD camera and tried to find a process of image enhancement in accordance with the characteristics of the CCD. And we also developed the method of transforming BIN image file to BMP file for the application on the windows program. Digital image was acquired suitable to coordinate measurment after image enhancement as histogram analysis to BMP image, equalization, brightness, contrast, noise elimination, and sharpening. Also we acquired pixel coordinate for target point on the object and tranformed to image coordinate. Next, we selected a part of automobile, executed bundle adjustment by method of this study and existing photogrammetric surveying, and consequently examined 3D accuracy and efficiency. In addition, we suggested 3D measurement method applicable to the whole range of industry by accomplishing fast and efficient modeling technique by means of digital photogrammetry.
