True three-dimensional aerial remote sensing geological interpretation method in engineering geological investigation

Abstract

The invention relates to a true three-dimensional aerial remote sensing geological interpretation method in engineering geological investigation. In interpretation measures, aerial remote sensing images are generally interpreted based on a stereoscope interpretation mode of papery black and white image pairs, in most of the interpretation measures, only stereoscopic observation interpretation in fixed scale is performed on the aerial image pairs, interpreted target image pairs are difficult to position and search, rendition of interpretation result is complex and inaccurate, and effective utilization of the aerial remote sensing images is constrained. In the method, aiming at a digital photogrammetry single stereoscopic image pair, a digital remote sensing geological true three-dimensional interpretation environment is created, so that a remote sensing geological interpretation method is improved, and accuracy of extraction of geological information is improved. With the method provided by the invention, the transformation from a two-dimensional plane to the three-dimensional environment in the geological information interpretation process is implemented; in the geological information interpretation process, a full digital interpretation environment is implemented; the three-dimensional environment is created based on a red-and-blue glasses mode, requirements on software and hardware environments are simplified, hardware devices are portable for field operation, and convenience for field work is also improved.

Problems solved by technology

However, in terms of interpretation methods, the stereoscopic interpretation mode based on paper black and white image pairs is generally used. Most of them only perform fixed-scale stereoscopic observation and interpretation of aerial image pairs. The drawing is cumbersome and the accuracy is poor, which restricts the effective use of aerial remote sensing images to a certain extent.
