摘要/Abstract

摘要： 由于缺少位姿信息,众源空中全景影像无法在地理信息空间中精确定位定向,本文提出了基于透视变换的众源空中全景位姿解算方法。首先阐述基于透视变换的球面全景空间交会方法原理,设计了位姿解算方案;其次构建了球面全景模型,使用透视变换实现了“平-球-平”模型变换;然后依据模型变换的变形特征,设计了迭代重加权最小二乘法解算位姿参数;最后以登封市纸坊水库空中全景影像为案例,验证了本文方法的可行性和可靠性。

Abstract: For the lack of position-attitude information, crowdsourcing aerial panoramic imaging is not able to precisely locate and orient in the geographic information space.A perspective transformation-based method of position-attitude calculation is proposed. First of all, the principle of proposed method is illustrated and the calculation scheme is designed. Secondly, spherical panorama model is constructed and “flat-sphere-flat” model transformation is implemented by perspective transformation Meanwhile, iterative reweighted least squares(IRLS) is designed for position and attitude calculation based on the deformation characteristics of model transformation. Finally, feasibility and reliability of the method are experimentally verified by using aerial panoramic images of Zhifang reservoir as a case.

Key words: crowdsourcing aerial panoramic imaging, perspective transformation, IRLS, position-attitude calculation, overseas battlefield environment reconnaissance
