摘　　要：涉及红外图像处理技术领域,提出了一种基于多向的红外焦平面阵列盲元检测方法:首先通过十字向的一维算子计算出该点横向和纵向的最大值和最小值,然后通过对角向的一维算子计算出该点对角方向的最大值和最小值,再由十字向和对角向一维算子的最大值和最小值分别获得该点二维方向的最大值和最小值,最后通过阈值判断该点是否为盲元点。通过文中算法不仅可以准确检测单个盲元,同时对于水平、垂直或对角向上连续的两个或多个盲元也可以准确检测得到;所需的存储开销低,运算简单,具有良好的通用性及可移植性,只需通过在软件中增添相应代码即可实现该功能,不会增加额外的硬件成本,降低了研制难度,缩短了研制周期。Based on the field of infrared image processing technology,a multidirectional infrared focal plane array blind element detection method is proposed.At first,the crossdirectional onedimensional operator is used to calculate the maximum and minimum values of the point at horizontal and vertical directions.And then,the maximum and minimum values of the point at diagonal direction are calculated by the diagonal onedimensional operator.The maximum and minimum values of the crosswise and diagonal onedimensional operators are used to obtain the maximum and minimum values of the point at twodimensional direction.At last,whether the point is a blind point or not is judged by a threshold.A single blind cell is not only accurately detected,but also two or more blind cells can be accurately detected,which are continuous at horizontal,vertical or diagonal directions.The required storage cost is low,the calculation is simple,and it has good generalization and portability.This function can be realized by adding corresponding code in the software without additional hardware cost,greatly reducing the difficulty of development and shortening the development cycle.
