Precision Single-line Dimension Measurement Using CMOS Image Sensor and Photometric Interpolation

A simple, flexible and programmable CMOS camera is presented in this paper. This camera is primary designed for precise single-line dimension and position measurements with subpixel resolution, but allows also a monochrome image acquisition that helps in camera positioning. Information from adjacent lines is also used to improve the single-line resolution. Camera is designed as a stand-alone device and uses the USB connection only as a remote terminal in the setup phase.
