| Abstract: | 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. |
