热图像与瞄准镜分划图像实时叠加处理系统研究

热像仪是夜战中用于观察和瞄准的重要装备,但目前装备的某些坦克和装甲车辆上的热像瞄准镜,本身并不具有瞄准分划,因而也就很难获取目标更多的信息,限制了对目标进行有效的瞄准射击:为了使其热像瞄准镜同样具有坦克微光瞄准镜所具有的功能,作者利用高速数字信号处理器ADsP21535开发评估板,研究设计了热图像和瞄准镜分划图像实时叠加处理系统,从而较好的解决上述问题.

Real-time Processing System of Superposing Thermal Image and Collimator Graduation Image Based on DSP Chip

Thermal imager is an important observing and aiming device for night operation, but some of such devices fail to fulfill their functions of aiming graduation, hence it is hard for them to collect enough target information and its effective shooting cannot be achieved. In order to have the same functions as low level light imager used in armored vehicles, this article offers a real-time image processing system that superposes collim-ator graduation image and thermal image, based on high- speed DSP evaluation board-ADSP21535.
