摘要
针对目前立体对图像同步采集问题,提出一种基于S3C6410处理器和WinCE6.0系统的实时同步采集方案。首先,完成立体摄像模块硬件设计;其次,开发相应的OV3640摄像头驱动程序并定制WinCE6.0操作系统;最后,开发基于DirectShow技术的立体摄像系统应用程序。应用程序利用摄像数据流反馈实现左右格式立体对图像的同步采集,关联左右两路摄像数据流,基于视差约束实现双摄像采集帧同步。系统利用ARM11处理器的数据处理能力和WinCE系统的可裁剪,提高了嵌入式立体摄像系统的可靠性与便携性。
Aiming at the problem existing in the synchronous capture of the stereo pair image, a method for the real-time synchronous capture based on S3C6410 processor and WinCE6.0 embedded system is proposed. Firstly,the hardware design of stereo camera module is completed. Secondly, the corresponding OV3640 camera driver is developed, and the configuration of WinCE6.0 system is completed. Finally, the application program of stereo camera system based on DirectShow technology is developed. It introduces the feedback of the camera stream to realize the real-time synchronicity of the stereo pair image capture system, associates left camera data stream with right camera data stream, and then realizes the frame synchronization based on the parallax constraint. Combining the data processing ability of ARMll processor with the tailorability of WinCE embedded system,this system improves the good reliability and portability of the embedded stereo camera system.
