Abstract

The invention discloses an iterative self-inspection adjustment method for an area network based on a beam method. The adjustment method includes obtaining the initial image point coordinates of the feature point with the same name on the image through image matching technology, and obtaining the initial outer orientation element value of the image. And use the initial outer orientation element value to build a regional network, construct a variety of additional parameter model combinations to iterate and output the adjustment results, judge the adjustment results, if the requirements are met, then output the additional parameter values, if not Then iterate until the requirements are met, which solves the problem of single model and limited cameras in the traditional self-checking method, prevents excessive parameterization in the process of self-checking, and can also fit the system error to the greatest extent during the adjustment process Therefore, the present invention can be used not only for the system error of the camera itself, but also for the correction and compensation of errors introduced by other systems during the adjustment process.

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...
