摘要/Abstract

摘要： [目的] 高光谱相机是重要的低空数据采集装备之一，相机安置参数标定是生成高精度DOM影像成果的关键。本文提出了一种高精度标定方法。[方法] 通过动态调整安置参数，准实时恢复线阵影像的外方位元素，计算影像点云，并在同一视角下将其与已知高精度点云数据进行综合特征配准，实现相机安置参数的高精度标定。[结果] 利用标定所得参数进行影像纠正并生成DOM数据，不同条带间影像拼接无明显偏差，无需进行二次处理，显著提升了作业效率。[结论] 生产实践表明，该方法切实可行，可用于其他线阵相机安置参数标定。

Abstract: [Purposes] Hyperspectral cameras are important instruments for low-altitude data acquisition,and accurate calibration of camera mounting parameters is essential for generating high-precision DOMs.A high-precision calibration method is proposed. [Methods] By dynamically adjusting the mounting parameters,the exterior orientation elements of line-scan imagery are recovered in near real time,and image-based point clouds are generated.Under the same viewing geometry,these point clouds are registered with known high-precision point cloud data through integrated feature matching,enabling high-accuracy calibration of the camera mounting parameters. [Findings] The calibrated parameters were applied to image rectification and DOM generation.The resulting DOMs exhibited no obvious stitching errors between adjacent flight strips,eliminating the need for secondary processing and significantly improving operational efficiency. [Conclusions] Practical applications demonstrate that the proposed method is feasible and effective.The method can also be extended to the calibration of mounting parameters for other line-scan cameras．

Key words: line-scan camera, mounting parameter calibration, comprehensive feature registration
