基于简化Slerp模型的三线阵影像定向片法平差
Orientation Image Adjustment of Three Line Images Based on Simplified Slerp Equation
摘要
Abstract
The principle of the bundle adjustment of three-line array images with Orientation Image(OI)method described by quaternion was discussed at first. Aiming at the form complex and compute intensive of the Spherical linear interpolation(Slerp)equation in bundle adjustment, a way to simplify the Slerp formula was proposed according to the characteristics of OIs, and the new mathematical model of bundle adjustment based on the simplified Slerp equation was set up. The results of several experiments with ADS40 images showed that better positioning accuracy could be achieved when the camera attitude being interpolated using Slerp equation than the traditional way of Euler angles, and the proposed method doesn't only do any bad to triangulation results, but also can significantly reduce the complexity of the bundle adjustment model and improve the speed. It is another ideal approach for the bundle adjustment of three line images.关键词
