Abstract

C-mount lenses are typically used in applications in which the equipment is preset for a given application. Fixed applications are fine for many uses, but the inability to provide automated features to this series of cameras limit their use. One limitation would be for the application on a robotic system which must adjust itself due to its changing environment. This research shows that a cost effective C-mount motor controlled camera lens and a C -mount camera may be automated for applications such as autonomous vehicles or robotic applications. By designing a computer automated C-mount lens controller and custom automation software, a host system could have automated vision capability. Control techniques used for video and still cameras were developed in software to perform auto-focus and auto-exposure control of a lens. This architecture allows the use of numerous C-mount cameras and C-mount motor controlled zoom lenses.
