摘要
航空长焦距倾斜相机在高空拍摄地物成像的时候具有倾角大、分辨率高、重叠区域广的特点。通过对多幅大倾斜图像的绝对定向、相对定向、影像匀色、拼接缝搜索和消除等问题进行分析,建立了航空长焦距倾斜相机影像全自动无缝镶嵌流程,并进行了试验验证。实验表明,自动无缝镶嵌结果满足定位精度既定要求,该流程设计具有很高的实用价值。
The character of aerial long-focus sloping camera image has the features of big obliquity, high resolution and big overlaped. Through analyzing absolute direction, relative direction, image unifier color and integrated seam search and remove etc., the auto seamless mosaic process for aerial long-focus sloping camera images is established, then an experiment is executed to test. The test results show that the auto seamless mosaic meets the requirement of direction precision, and this process design has practicability.
