摘要
通过对红外探测器开窗口功能的研究,设计了特定的积分时间信号,在牺牲一定实时性的前提下,不仅实现了帧频的大幅提高,而且实现了两种不同帧频图像的同时输出,其中低帧频的满幅图像输出到监视器中供人观察,高帧频的窗口图像送到跟踪器中用于跟踪算法处理,满足了一些对帧频要求比较高的场合。通过在FPGA+DSP的硬件平台上的实现,验证了该方案的可行性,同时指出了开窗口会造成阵元的响应出现差异这一问题。
IRFPA with region of interest is researched and specific integral time signal is designed,which not only rises frame rate greatly,but also realizes outputs of two different frame rate image at the same time at the cost of the loss of real time.One of two different frame rate image is lower frame rate and is used to display,the other is higher frame rate and is transmitted to tracker which makes tracking arithmetic process.This project is realized at the hardware plat of FPGA＋DSP and is proved to be viable,the response difference that arises from region of interest is pointed out finally.
