| 摘 要： | 本文根据倾斜航摄仪中多镜头相机间的位置结构，分析了倾斜影像航向、旁向重叠度与飞行速度、曝光间隔时间、航线间隔等参数之间的关系，在此基础上推导出一种适合任意数量、任意位置相机所拍影像重叠度的计算公式。试验结果表明，该方法提高了倾斜摄影参数设定的准确度，为后期质量保证提供了必要的基础。

| Abstract: | According to the position structure of the multi-lens cameras in the tilting aerial camera, the relationship between the corresponding coverage area of the oblique image, course, lateral overlap degree and flight speed, exposure interval time, route interval and other parameters is analyzed. On this basis, a formula for calculating the overlap degree of images taken by cameras at any number, any angle and any position is derived. The result proves that this method improves the accuracy of setting parameters of tilt photography and provides a necessary basis for the quality assurance of the later process. |
