摘要:

随着无人机的广泛应用,其相机安置方式及摄影姿态的任意化,造成影像基线方向多样化,利用传统的航空摄影测量方法处理此类影像较为困难。本文提出了一种基于本质矩阵恢复此类无人机影像位姿的方法。经试验证明,本文提出的定向测量不仅可以快速确定基线方向,求解影像外方位元素,而且重投影误差在1个像素以内。

关键词: 本质矩阵, 连续像对相对定向, 基线, 影像位姿

Abstract:

With the widespread use of UAV,the emplacement of the camera and direction of the camera can be arbitrary.This leads to the diversification of the image baseline direction.It is difficult to process such images with traditional photogrammetric method.This paper proposes a strategy based on essential matrix for recovering pose of aerial image.It is proved that the orientation measurement proposed in this paper can not only determine the baseline direction quickly and solve exterior orientation parameters of images,but also guarantee the re-projection error within one pixel in terms of accuracy using our proposed strategy.

Key words: essential matrix, continuous relative orientation, baseline, image position
