通过分析多种图像采集系统案例,采用一种基于达芬奇(DaVinciTM)平台技术的CMOS图像采集处理的解决方案。其中,达芬奇技术能够很好地处理ARM与DSP之间协同工作的问题,同时使ARM与DSP能各自发挥自己功能,大幅度提升采集图像的质量输出。通过研究实施CPLD进行时序控制,较好的实现图像采集和处理的稳定而快速的结合,形成一套可以获取较高帧率、能够自由缩放及按适当比例输出的软硬件图像采集处理系统。
By analyzing a variety of image acquisition system cases, a solution based on DaVinciTM platform technology CMOS image acquisition processing. Among them, DaVinci technology can well deal with the problem of interworking between ARM and DSP, and at the same time enable ARM and DSP to play their own functions and greatly improve the quality output of the collected images. Through the research and implementation of CPLD for timing control, it is better to achieve a stable and fast combination of image acquisition and processing to form a set of software and hardware image acquisition and processing system that can achieve higher frame rate, can be freely scaled and output at an appropriate rate.
