Description

technical field

[0001] The present invention relates to a stereoscopic imaging method of a panoramic image pair in a hole, and more particularly relates to a method for forming a panoramic image pair image of the hole wall by using a biconical mirror, and an imaging device to realize imaging of the image pair image and a stereoscopic image pair image for the wall of a borehole. The solution method; it breaks through the technical problem that the previous borehole imaging cannot realize three-dimensional imaging in the borehole, promotes the further development of borehole imaging technology, and is more suitable for fine in-hole detection. Background technique

[0002] As the rock mass suffers from various tectonic movements and shallow geological transformation, there are various types of structural planes with different scales, different occurrences, and different properties in the rock mass. The spatial distribution and occurrence status of these structural planes It con...
