基于PCI-GXL系統(tǒng)對多源遙感影像區(qū)域網(wǎng)糾正精度的研究
[Abstract]:Based on the PCI-GXL software platform, this paper corrects the remote sensing image with multiple sources and phases, studies the change of the precision of the area network by using the change of the number of control points, and makes use of the internal precision algorithm of the PCI-GXL software. The high precision RPC parameters of remote sensing images are used to restore the spatial attitude of satellite images and to test the effect of the connection points in the regional network on the stability and positioning accuracy of the whole regional network. In this paper, the change of connection points is analyzed experimentally, the remote sensing image with high positioning accuracy is removed from the whole area network, and the variation of the precision of the whole area network is viewed. Through the analysis and evaluation of the experimental data precision, it is further verified that the PCI-GXL system can make full use of the control function of the image connection point with high positioning accuracy to improve the accuracy of the whole area network when the area network is corrected. In the future, when the remote sensing image is corrected in the regional network, the existing image source can be used as the control source to reduce the demand of the field control point, to avoid the measurement work of too many field control points, and to improve the efficiency of remote sensing image production.
