Image sensors based on the CMOS technology became commonly used sources of image information in PC-based vision systems. Image information is converted directly on the chip to a stream of synchronous digital data which can be transferred to a PC using the cost-effective interface introduced in this contribution. The CMOS image sensor together with the developed interface can be considered as a simple...
This paper presents an edge detection method for single dimensional image signal. The method is intended for embedded applications. Two dimensional signal processing requires great memory and powerful image processor which is a problem in low cost embedded applications (e.g. (Trestik, 2005)). Necessity of special edge detection method has arisen during an intelligent image sensor developing. The intelligent...
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...
