CONF ON ACQUISITION, TRACKING, AND POINTING 5
作者: LIU, ZL North China Research Institute of Electro-Optics (China)
After the stage of pointlike target tracking, the tracker comes to the stage of area target tracking. This paper considers the situation in which the FLIR image contains a number of targets. The targets are compact. T... 详细信息
