Abstract

The invention discloses a bundle method block iteration self-checking adjustment method. The adjustment method comprises the following steps: acquiring initial image point coordinates of feature homonymy points on an image through an image matching technology; obtaining an initial exterior orientation element value of the image and constructing a regional network by using the initial exterior orientation element value, constructing a plurality of additional parameter model combinations for iteration and outputting an adjustment result; and judging the adjustment result; if requirements are met, outputting the additional parameter values, or else, performing loop iteration until the requirement is met. The problems are solved that the model of the traditional self-checking method is singleand the suitable cameras are limited, the bundle method block iteration self-checking adjustment method can prevent the problem of excessive parameterization in the self-calibration process, can fit system errors to the maximum extent in the adjustment process, and can be used for correcting and compensating errors introduced by other systems in the adjustment process as well as system errors of the cameras.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to the self-checking and calibration of different shooting environments and different cameras to eliminate system errors. Background technique [0002] At present, due to the development of science and technology, cameras are no longer traditional single-lens, multi-lens and multiple image planes. Various cameras have appeared one after another, and their system configuration and imaging methods have changed a lot. Many traditional calibration methods are no longer used. The self-inspection calibration block adjustment can expand the adjustment model for regular systematic errors. During the adjustment process, not only the optical distortion system error of the camera is considered, but also the systematic error (atmospheric vibration, engine airflow) brought by the aerial photography aircraft. , Film deformation, atmospheric refraction and environment to correct the system...
