| 摘 要： | 利用飞速发展的FPGA技术,在图像采集前端实现Bayer插值变换。比较了常用的3种插值方法,选用计算复杂度较高但图像质量最佳的Optimal Recovery方法。采用Lattice的FPGA芯片LFECP2-M50,实现1 208×1 024图像,12 f/s,实时Bayer转换。给出了实时采集图像结果,显示了插值变换前的原始图像,计算了变换后图像的峰值信噪比PSNR。总结基于FPGA的彩色图像Bayer插值变换实现方法,利用FPGA技术,采用并行算法结构,实时实现了大尺寸图像Bayer转换。 |
| 关 键 词： | 插值变换 峰值信噪比 可编程门阵列 并行算法结构 |

| Abstract: | In an actual image capturing system,the simple methods of interpolation frequently results in the boundary distortion,the image degradation and the diffuse color.Those available and complicated ways are usually implemented by Host(PC),because it is difficult to achieve the interpolation by adopting the embedded CPU on the end of system.The Bayer interpolation was implemented in the embedded system with the rapid development of FPGA techniques.The three methods of interpolation were compared,and the optimal ... |
