| Abstract: | Focusing on the practical requirements of the monitoring video controller in rail traffic dispatch displaying system, this paper introduces the basic principle of bi-cubic interpolation algorithm and anti-aliasing filter, proposes the function partitioning of the image scaling technology implementation, which is the core of the monitoring video controller. It also analyzes the work flow of image scaling technology implementation based on FPGA, discusses the detail functions of input buffering, image scaling, frame frequency adjustment and image mosaicking, completes the simulation of this technology, and compares the results of simulation between this technology implementation and traditional image scaling. |
