This invention discloses a multi-view optical three-dimensional visualization gas monitoring system and method, relating to the field of gas leak monitoring. It solves the problems of existing technologies, such as difficulty in simultaneously identifying gas types and visualizing their three-dimensional spatial distribution, and insufficient real-time monitoring accuracy. This invention simultaneously acquires multi-view infrared and visible light images through a multi-view collaborative imaging module, adaptively switching between wide-spectrum and narrow-band filtering states based on spectral anomaly intensity to obtain characteristic images of gas clouds. Based on a multi-view stereo matching algorithm, it constructs a three-dimensional spatial point cloud of the gas cloud and locates the leak source. It extracts spectral features for comparison to identify gas types and invert concentrations. Finally, it fuses gas information with the three-dimensional point cloud and real-world images to achieve three-dimensional visualization output and audio-visual alarm linkage. This invention achieves automated, high-precision, and real-time three-dimensional visualization monitoring of gas leaks.

To obtain a crustal deformation stereoscopic image processing system that can accurately color-code images based on elevation differences that take into account vertical and horizontal components, even when crustal deformation causes displacement in both vertical and horizontal directions. [Solution] A red stereoscopic map Gbi (image) is generated based on a new DEM of a predetermined area (S12), and a grayscale red stereoscopic map GBgi is generated (S16). On the other hand, the new DEM (post-earthquake) and the pre-earthquake (old) DEM (old DEM) are differentiated (simple difference) to highlight the areas of change (S24). Then, these areas of change are color-coded according to the degree of subsidence and uplift (S26).
