摘要
为解决由于相机高速运动而导致的图像模糊,利用定点DSP芯片TMS320C6416和维纳滤波算法实现电子稳像。研究了运动模糊的退化模型,阐述了维纳滤波进行图像恢复的原理。介绍了利用定点DSP(TMS320C6416)完成电子稳像的关键技术,完成字长为32bit的FFT运算,充分发挥DSP的DMA功能来提高处理速度。分析了恢复图像中存在的振铃效应和边沿效应,给出了实验结果。
To absolve image blur for high speed camera, fixed-point DSP TMS320C6416 and wiener filtering algorithm were adopted. Degeneration model for moving blur was researched. The principle of Wiener filtering was explained. FFT of 32bit was completed and DMA function of DSP to enhance processing speed was exerted. Ringing effect and edge effect were analyzed. The test results were presented.
