| 摘 要： | 针对一种非矩形Retina-like探测器进行建模与仿真,研究其相向运动过程的模型.在不同场景及不同模糊度条件下对Retina-like探测器及矩形探测器的图像进行质量评价,不同的评价参数均表明Retina-like探测器在相向运动过程中的成像质量优于矩形探测器,具有抗辐射状模糊的效果,在相向运动过程中有明显的优势,为探索高速相向运动成像过程中的非矩形探测器面阵设计提供帮助.

| Abstract: | A type of non-rectilinear Retina-like sensor has been modeled and simulated in this paper,and the model for high speed forward motion was especially studied.The image quality of Retina-like sensor and rectilinear sensor were assessed for the cases of different scenes or at different degeneration degrees.It was found that all the three image quality assessment parameters indicated that the image quality of Retina-like sensor was superior over that of rectilinear sensor.In addition,Retina-like sensor could re... |
