Abstract


Infrared imaging detection and tracking system, the process is multi-dimensional signal ( two-dimensional space and one time dimension ) , and are passive detection technology has been widely used in many fields , such as missile guidance , medical and intelligent transportation systems . With the application requirements continue to increase , as early as possible finding the target , and therefore long-range , low signal-to-noise ratio under infrared small target detection and tracking technology to become one of the current research focus . Real - time detection and tracking of the infrared image small moving target in complex background study , the following major elements: (1) analysis and research on infrared small target detection and infrared imaging characteristics may occur in the infrared image bright and dark targets , proposed a method based on local contrast enhanced lateral inhibition . Experimental results show that the method at the same time enhance the bright and dark target overall complex background have a better ability to inhibit an effective solution to the bright and dark in the complex context of the problem of adaptive detection of small targets . (2) on the basis of analysis of the existing target tracking method focuses on data association in multi- target tracking technology . Combination of infrared staring focal plane imaging characteristics , proposed and implemented a multi-feature adaptive integration methods , so that the target multi-feature information in accordance with the degree of stability of each characteristic to a more reasonable weight value integration, to ensure the data associated correctness and reliability . (3) describes the composition of the infrared imaging tracking system to study a complex context of infrared target detection and tracking algorithm , multi- target tracking , the main tracking target tracking , monitoring field of view of other possible targets enhanced target tracking stability . Analysis of to discuss the algorithm scheduling problem tracking process due to changes in the target state , the switch between surface target with small target detection and tracking algorithm . (4 ) for the algorithm application specific image processing hardware system , real-time implementation of the algorithm . On the basis of the analysis of DSP software program optimization method , the algorithm is more time-consuming function module and space block calculation time pipeline complex background infrared target detection and tracking algorithm in multi-DSP parallel distribution system .
