为了获取具有较大视场的图像数据,设计了一种基于线阵CCD的高分辨率周视图像实时采集系统。完成了系统各硬件电路的模块设计,并采用VHDL语言编程设计了TCD1209线阵CCD驱动时序及A/D转换等控制时序。提出了基于VC多线程技术的线阵CCD图像动态实时采集的新方法,并详细介绍了在Visual C++6.0环境下,实时图像采集应用程序的实现过程。软硬件仿真与调试达到了预期的要求,完成了周视图像的实时采集,实验结果表明该方案具有一定的可行性。
In order to obtain the image data with larger field of view, a real-time high-resolution image acquisition system based on linear CCD is designed. Completed the system hardware circuit module design, and using VHDL language programming TCD1209 linear array CCD driver timing and A / D conversion control timing. A new method of dynamic real-time acquisition of linear array CCD images based on VC multithreading technology is proposed. The realization process of real-time image acquisition application in Visual C ++ 6.0 is introduced in detail. The hardware and software simulation and debugging meet the expected requirements and the real-time acquisition of the surrounding image has been completed. The experimental results show that this solution is feasible.
