【摘要】：野外地质剖面考察是开展地质研究的一项重要工作。在野外地质考察过程中,为了直观展示地质剖面的细节信息,往往需要拍摄大量的影像。同时,为了提高细节信息的展示程度,这些影像往往分辨率高,但视场角小,所以单一的影像注定无法兼顾的展示地质剖面的整体信息和细节信息。因此基于这种同时展示整体和细节信息的需求前提下,本文在自主研发的Mosaic of Image Program(MIP)图像拼接系统的基础上,对野外拍摄的影像进行了拼接处理,形成地质剖面的长条带全景影像。为了提高拼接处理的精度,本文对高精度的相机检校、畸变校正及MIP的地质剖面应用等方面进行了研究。在湖南古丈县地质遗迹剖面的实际处理中,完成了300多张高分辨率影像的快速拼接,获得了良好的数据记录和展示效果,拼接影像几何失真小于2像元。本文实现的技术手段在野外地质剖面考察中具有良好的应用前景。
[Abstract]:Field geological profile investigation is an important work in geological research. In the process of field geological exploration, a large number of images are often taken in order to display the detailed information of geological section directly. At the same time, in order to improve the display of detail information, these images often have high resolution, but the field of view angle is small, so a single image is doomed to show the geological profile of the whole information and detail information. Therefore, based on the requirement of displaying the whole and detail information at the same time, on the basis of the self-developed Mosaic of Image Program MIP image mosaic system, the field images are stitched. A panoramic image of a long strip forming a geological profile. In order to improve the accuracy of stitching, this paper studies high precision camera calibration, distortion correction and the application of MIP in geological profile. In the practical processing of geological relic section in Guzhang County Hunan Province more than 300 high-resolution images have been quickly stitched and good data recording and display effect have been obtained. The geometric distortion of the stitched image is less than 2 pixels. The technical means realized in this paper have a good application prospect in the field geological profile investigation.
