| 英文摘要 | The CMOS image nonuniformity and its correction methods were researched to improve the relative radiation quality of aerial remote sensing image products. Taking the new CMOS image sensor CIS2521F as an example, the nonuniformity characteristics affected by dark current noise, average gay and double channel readout were researched through the experiments of the integrating sphere observation. Then, the two-point linear correction method based on the observation data was used to remove the column strip noise related to column amplifiers. Finally, a correction method based on the statistical gay difference near the mosaic seam was used to wipe off the mosaic phenomenon related to double channel readout. Experimental results indicate that the nonuniformity of the sphere image has changed from 4.4 into 2.4 after single channel correction, and the manual interpretation difference is disappeared after double channel correction. The remote sensing image after correction is uniformity and satisfies the interpretation requirement. © 2016, Science Press. All right reserved. |
