CCD传感器在进行帧转移过程中会产生Smear效应,对航天、遥感、空间侦察应用来讲,必须对它进行消除,以避免影响目标检测。在对Smear效应产生机理以及星图成像性质进行分析的基础上,提出了一种帧转移型CCD传感器Smear效应消除方法。利用Smear效应对应行列灰度和高于其他区域的特征检测出Smear效应位置,并排除Smear效应位置处的星点,通过双三次插值方法消除Smear效应。实验证明,该方法能有效去除Smear效应。 CCD sensor in the process of frame transfer will have a Smear effect, aerospace, remote sensing, space reconnaissance applications, it must be eliminated to avoid affecting the target detection. Based on the analysis of the generation mechanism of Smear effect and imaging properties of star image, a method of eliminating Smear effect of frame transfer CCD sensor is proposed. The Smear effect position was detected by using the Smear effect corresponding to the gray level in the matrix and higher than those in other regions, and the star point at the Smear effect position was excluded. The Smear effect was eliminated by the bicubic interpolation method. Experiments show that this method can effectively remove Smear effect.
