为动态显示扇形搜索空域的全景图像
必须设计专用的图像处理器
以解决快速搜索与人眼观察之间的矛盾。某舰载小型光电跟踪仪
搜索区域为沿水平和垂直方向分别扫过20倍瞬时视场的空域
搜索视场从1.7°×1.3°扩大为34°×26°。图像处理器以TMS32010DSP为核心
外加直方图、分类表存储器等辅助电路
完成实时图像采集、存储、拼接、显示、更新等功能
适应42.5°/s的扫描速率
获得比光学系统本身大20倍的搜索视场。
A special image processor has been designed to display the image of all searched space
resolving the discrepancy of quick searching and visual observing. For a warship bound mini opto electronic tracker
the dimension of searched area is 20 times of the instantaneous FOV vertically and horizontally. Thus
the searching FOV can be magnified from 1.7白1.3? to 34白26?. The image processor based on DSP TMS32010
sets up an additional memory of histogram and classification
realizing image sampling
memory
mosaic
display and alternating
suiting for the searching velocity of 42.5?/s
and obtain a search field of view 20 times larger than that of the optical system itself.
