摘　　要：提出了大幅面拼接航摄仪的两种平台检校方法,并对检校公式进行严密推导。将现有影像按照拼接模型进行拆分,获得大倾角的子影像,由此子影像数据对两种平台检校方法进行验证,根据平台检校结果对检校方法存在的问题和适用性进行了分析。Multi-head camera is widely used in aerial photography recent years.Platform calibration is the key process to mosaic sub-images to one virtual image.Based on the platform calibration model and photogrammetric theory,two platform calibration methods were put forward and their calibration formulas were deduced rigorously.These methods were tested by simulated data.According to the result,the applicability and accuracy of these two methods were proved.These methods could be used in platform calibration even when overlaps of sub-images are small.
