In remote sensing photogrammetric applications, inner orientation parameter (IOP) calibration of remote sensing camera is a prerequisite for determining image position.However, achieving such a calibration without temporal and cerave baume hydratant spatial limitations remains a crucial but unresolved issue to date.The accuracy of IOP calibration methods of a remote sensing camera determines the performance of image positioning.In this paper, we propose a high-accuracy self-calibration method without temporal and spatial limitations for remote sensing cameras.Our method is based on an auto-collimating dichroic filter combined with a surface micromachining (SM) point-source focal plane.
The proposed method can autonomously complete IOP calibration without the need of omnia 943 lever outside reference targets.The SM procedure is used to manufacture a light transceiver focal plane, which integrates with point sources, a splitter, and a complementary metal oxide semiconductor sensor.A dichroic filter is used to fabricate an auto-collimation light reflection element.The dichroic filter, splitter, and SM point-source focal plane are integrated into a camera to perform an integrated self-calibration.Experimental measurements confirm the effectiveness and convenience of the proposed method.
Moreover, the method can achieve micrometer-level precision and can satisfactorily complete real-time calibration without temporal or spatial limitations.
