基于FPGA的双线性内插方法实现MEE的畸变实时校正

FPGA-Based MEE Distortion Correction Real-Time System Design Using Bilinear Interpolation

设计了医用电子内窥镜 (MEE)畸变实时校正硬件系统 ,以有效改善图像的畸变失真 ,实时地反映病变部位。采用FPGA作为图像处理器 ,用VerilogHDL语言设计了双线性内插模块 ,实现了MEE标准视频图像的硬件双线性插值。系统延迟 4 0ms,校正前、后图像的相对畸变分别小于 - 2 0 %和± 1%。

The hardware circuit of real time distortion correction system of Medical Electronic Endoscope(MEE) is designed and implemented to improve the distortion image and reflect the pathological changes part. FPGA is used as the video processor, and bilinear interpolation module is designed using Verilog HDL. The hardware bilinear interpolation of MEE standard video is implemented. The system delays 40ms.The relative distortion before and after the correction is separately smaller than 20% and ±1%.
