| 摘 要： | 从空间分辨率、几何纠正精度,辐射精度和纹理4个方面对HJ-A-CCD图像进行评价,并与同范围的CBERS-02B-CCD图像进行比较,结果表明:HJ-A-CCD的信息量、对比度、几何定位精度等方面与CBERS-02B-CCD相比尚有差距;可通过图像增强处理方法改善图像质量,HJ-A-CCD数据仍有很大的图像改善空间,并在国土资源调查、城市规划、环境监测、测绘等诸多领域有着广阔的应用前景.

| Abstract: | The quality of HJ-A CCD image is evaluated from four aspects such as image spatial resolution,geometric correction,radiation precision and texture in this paper.After the comparison between the HJ-A-CCD image and CBERS-02B-CCD image of the same area.The result shows: CBERS-02B-CCD was found to produce image with much better information capacity,contrast,geometric etc.However,the image quality can be proved greatly by image enhancement processing such as contrast stretch.and then,the image will be widely use... |
