| Abstract: | Equivalent large frame camera,composed of multiple CCD cameras and involving synchronized exposure as one of its key technologies,can form a wide field of view and play a significant role in digital phtogrammetry.Therefore,the research on a synchronized exposure method was conducted with solid state optronics relay as the key component in the paper,and furthermore,experiments on the performance of synchronous exposure were carried out.The data were analyzed with statistical analysis method and the advantages,compared with those of the traditional electromagnetic relay methods,were verified.The experiment showed that the method could satisfy the requirements of large-scale digital photogrammetry. |
