纠正图像 meaning in English
remedial frames
Examples
- Beside spherical mosaic technique , the method of sampling source image to extract information on sphere is given , the difference of luminance and color between images due camera parameter change while image captured is corrected to remove visible boundary on panorama
此外，本文还给出了从原始图像中采样生成球面全景图的方法，该方法可以纠正图像拍摄时相机参数变化导致图像间整体亮度的差异，使生成的球面全景图没有明显的拼接痕迹。 - Investigation using remote sensing ( rs ) technology can breakthrough the limits of traditional methods , make full use of its capability of integration , visualization , rapidity and vast - dimensions analysis , and get better results the paper takes the up - to - date landsat - 7 etm + data , which is the most widely used , and quickbird data , which has the highest resolution nowadays , and according the features of the data and landslides , processes the quickbird data with 1 : 10 000 dem orthophoto correction and the landsat - 7 etm + data as follows : ( 1 ) selecting optimal spectrum band : selects 753 bands as the optimal bands ; ( 2 ) image intensifying : selects the principle components processing method on the basis of comparing several image intensifying methods ; ( 3 ) rigour geometric direction : corrects the geometric distortion of the map ; ( 4 ) image fusion : mainly takes his space transform fusion and resolution fusion method , and acquires maps with higher spectrum resolution as well as space resolution . after that , the visual effect of the image has been enhanced , and the interpretation precision
采用遥感技术，可以突破传统调查方法的限制，发挥其宏观、综合、直观、快速的特点，取得更好的效果。论文选取目前应用最广的陆地卫星最新系列landsat - 7etm +数据和空间分辨率最高的商业卫星quickbird数据作为主要的数据源，根据数据的特点及滑坡灾害应用特征，对quickbird遥感数据则基于1 ： 10000dem进行了正射校正，对etm +遥感数据进行了波段优选，选取了753作为最佳组合波段；图像增强，通过各种增强处理方法的效果对比，选择主成分分析法对图像进行增强；几何精校正，纠正图像的几何变形；影像融合，主要选取了效果较好的his空间变换融合和分辨率融合，得到的图像既具有较高的光谱分辨率，同时也具有较高的空间分辨率。经过上述数字处理，较好地改善了图像的视觉效果，提高了图像解译的精度。
