摘要
Abstract
A high efficiency algorithm for detecting infrared dim target based on digital signal processor (DSP) is proposed. It is designed especially for the cloud edge left after the image preprocessing of irregular clouds, and it is a searching algorithm based on improved notch filter after the background predicting. A DSP-based real-time image processing platform has been used to implement and test the algorithm in real scenarios. It is proved that the algorithm can restrain the negative effect of the residual cloud edges effectively. The detection distance reaches 26 km and the real-time processing speed can reach 75 Hz, The algorithm improves the signal-to-noise ratio of images significantly, which is beneficial to target detection.关键词
