The DMZ II (DaMianZhen II) camera uses a multi‐frame optical plane assembly to form a virtual ultra‐large array sensor (23 000 × 23 000 pixels). The geometric model of this aerial mapping camera, with one lens and 12 component CCD panchromatic arrays, is proposed. The new geometric model combines the well‐known global parameters with sensor‐specific local parameters for the individually installed CCD arrays. Test flight evaluations show that the model can improve the geometric accuracy from ±6 μm (1 pixel) to ±1·5 μm (1/4 pixel), equivalent to that of traditional single‐array imaging sensors, providing a multiple‐array large‐frame aerial mapping camera with high accuracy and efficiency.

新型超大画幅航拍相机DMZ II的几何校准模型

DMZ II（DaMianZhen II）相机使用多帧光学平面组件形成虚拟的超大型阵列传感器（23000×23000像素）。提出了一种具有一个镜头和十二个分量CCD全色阵列的航拍相机的几何模型。对于单独安装的CCD阵列，新的几何模型将众所周知的全局参数与特定于传感器的局部参数结合在一起。测试飞行评估表明，该模型可以将几何精度从±6μm（1像素）提高到±1·5μm（1/4像素），与传统的单阵列成像传感器相当，从而提供了多阵列大尺寸传感器。高精度，高效率的前置式航空测绘相机。
