摘要
为了推动"资源三号"(ZY-3)卫星影像数据早日为相关领域提供服务,文章采用主观评价和客观评价相结合的方法,对资ZY-3卫星三线阵图像的辐射特性进行了全面评价。分析结果表明,ZY-3卫星三线阵相机图像清晰,信噪比高,能够有效反映不同地物的细节特征,在量化深度和细节表现等方面具有优势。
TLC camera onboard ZY-3 is a new payload with stereo mapping capability,whose radiometric image quality needs to be analysed to improve its application in various fields. Subjective and objective methods are both employed in this paper to perform a thorough analysis. Images from ZY-3 TLC camera have high SNR, with details of different objects well expressed. Comparison with similar cameras shows the radiometric image quality of ZY-3 has significant improvement over that of CBERS-02B. ZY-3 TLC camera has higher quantization depth and better detail feature presentation than thost of SPOT-5 and ALOS.
