| 摘 要： | 基于四个独立数码相机构建的组合大面阵数码相机,克服了数码相机像幅小,基线短的缺点,满足高精度,高效率的大比例尺低空摄影测量应用.针对组合大面阵数码相机简易的机械结构带来了舷摄过程中机械变形问题,提出了基于每两幅影像重叠区内的同名点的相对自检校方法:针对不同投影中心的影像拼接成同一投影中心的虚拟影像的几何模型,提出影响成图精度的因素.实验证明,相对自检校有效纠正了航摄过程中机械变形,满足影像拼接的几何精度.

| Abstract: | To overcome the disadvantages of single non-metric camera with small format and short baseline,a composite camera was developed with the combination of four individual non-metric digital cameras.The large frame composite camera was able to meet low altitude photogrammetric applications with high accuracy and efficiency.Since small movements of one camera against the other cannot be avoided due to a simple and low-cost structure,a relative self-calibration method was proposed to make up error derived from de... |
