Layered survey and multi-dimensional identification survey and identification system and method

The invention relates to a layered survey and multi-dimensional identification survey and identification system and method. The system comprises: a data acquisition module; a data processing module that is used for processing the acquired surface feature image data in the following manner: converting the surface feature image data into a zeroth-layer data set conforming to an identification algorithm; processing the zeroth-layer data set, identifying basic geographic information in the zeroth-layer data set and calibrating to generate a first-layer data set; processing the first-layer data set, adding design standard attributes to surface features of the first-layer data set, identifying an influence range and an influence degree of surface feature epitaxy, and generating a second data set; processing the second-layer data set, adding engineering influence factor attributes to the surface features of the second-layer data set, and performing multi-dimensional identification on the surface features with the en
