摘要 | A new approach to measure the on-orbit point spread function of remote cameras is proposed here. Based on the classical step-edge method, a profound analysis about the influence of the tilted angle, size, interpolation, contrast, pixel saturation and noise of the step-edge image was made. The conditional step-edge image is first detected and then processed to weaken the impact of sampling phase in order to improve the precision of the measurement. The experiment on real remote sensing panchromatic data demonstrates the effectivity and credibility of the new method. Furthermore, the degraded image is restored using the measured point spread function, the quality of the image is significantly improved. |
