基于数字纠正的核线影像生成方法

Generating method of the stereo epiporlarline images based on geometric correction

围绕着利用航空立体影像对自动生成核线影像的问题,介绍了基于数字影像几何纠正的核线解析方法的实现过程。包括影像内定向、独立像对相对定向和基于数字影像几何纠正的核线解析。详细推导了数字影像几何纠正的核线解析与独立像对相对定向之间的关系,用相对定向参数来直接求解核线影像,并在计算机实现了该算法。最后对生成的核线影像的精度进行了分析,证实同名点在其垂直方向上的上下视差很小,从而证明采用这一方法来生成核线影像是可行的。

The problem of generating the epipolarline images automatically from aerial stereo images are discussed,and specifies the method based on geometric correction of image.The progresses include inner orientation,relative orientation and geometric correction for digital images to generate the stereo epiporlarline images.Their coordinate transforms are studied in detail and generated the epipolarline images directly by using parameters of relative orientation.This method making the two obtained epiporlarline images has so little parallax in vertical direction.The experiment proves that it's feasible to analyze the experimental data through this method.
