摘　　要：盲元数量是判定探测器性能的重要指标。通过9×9窗格响应法和中值滤波法进行盲元的检测,实现了盲元数量和位置的确定。运用中值滤波法初步确定了盲元检测率与图像灰度值之间的关系。采用改进算法进行盲元补偿,减少了硬件的占用率和图像的失真率,提高了盲元的补偿效果。The number of the blind pixel is an important parameter in the infrared imaging system. By the way of the 9 × 9 pane response method and the median filtering method, the number and position of the blind pixel is determined. The relationship between blind pixel detection rate and image grey value is determined by the median filtering method. With the improved algorithm to compensate blind pixel, the hardware occupancy rate and image distortion rate are reduced, the effect of blind pixel compensation is enhanced.
