remote sensing camera meaning in Chinese
遥感相机
遥控照相机
Examples
- The ccd space remote sensing camera imaging is different from traditional film imaging . the grain dimension of photosensitive emulsion is so small compare with the blurs of optical system that it can be ignored . but the ccd pixel dimension is a few times of the blurs of optical system
这里则采用模拟试验及计算机仿真的方法来研究在空间移变条件下的ccd遥感相机的影像分辨力和像质问题，这种研究不仅在理论上是一种补充，在工程实践上也很有实际意义。 - Under the condition of one pixel image motion , adopting the modulation method , the ratios of the mtf with image motion to the idea mtf are 0 . 591 . the difference amount of mtf is shown . they are analyzed that the types of optic system , obstructive ratio influence the mtf and the methods improvement the imaging resolution of remote sensing camera
在存在一个像元的像移量时在奈奎斯特频率处，卷积法的有像移的mtf值和理想的mtf值之比为0 . 591 ，仿真法在存在一个像元的像移量时，有像移的mtf值和理想的mtf值之比为0 . 667 ，从中看到了两者之间定量的差异。 - The relation of tthe ccd sensor imaging resolution and the mtf is gotten . when the mtf of space remote sensing camera is higher and the contrast of object is higher , it can be believed that the resolution of ccd sensor imaging is 1 . 6 times of the pixel dimension , in the mean while the mtf decreases 32 %
通过仿真得到了ccd探测器的目标影像的分辨力与ccd像元尺寸的关系，当航天光学遥感相机的mtf较高(仿真中镜头的mtf = 1 )且目标为高对比度时，得到ccd探测器的目标影像分辨力是其像元尺寸a的1 . 6倍，其光学调制度传递函数mtf下降32的结果。
