摘　　要：在图像制导末段应用图像相关匹配技术,可以起到稳定瞄准点的作用.用软件实现实时相关匹配具有灵活、可靠的特点.可根据目标及背景的不同置入不同的相关参数,以达到最佳的匹配性能.本文利用1K参考图像,4K搜索图像,通过采取优化搜索路径等措施,用TMS320C25高速处理芯片实现了SSDA算法,在40ms内能完成一幅4K多灰度图像的搜索,并给出位置误差。Use of the image registration technology in terminal guidance can stabilize the aiming-point. If implemented by software the technology has the additional advantage of flexibility and reliability. To get optimal tracking performance, different parameters can be selected in accordance with the existing background and targets. Brings forth a real-time registration algorithm SSDA using the method of optimum programing. This algorithm has been implemented using the TMS320C25 processor under the condition of 1K reference image and 4K searching image. It can copmlete the searching for a 4K searching image within 40ms.
