The invention relates to the technical field of mapping, in particular to a method for measuring image and inspecting quantity under the
light detection and
ranging (
LiDAR) three-dimensional environment, comprising the following steps of: respectively manufacturing a
digital surface model (DSM), a digital evaluation model (DEM) and a digital ortho image (DOM) according to
multiple sensor data obtained by the
LiDAR system, respectively layering and partitioning the DSM, the DEM and the DOM in advance, laminating the DSM, the DEM and the DOM to construct a three-dimensional environment, three-dimensionally measuring mark and intersecting, acquiring and
cataloging digital line graphic (DLG) elements, and inspecting quality of the DLG. The invention breaks through the limitation that photogrammetric survey needs complex
flow chart of
data processing and professional photogrammetric survey equipment and
software to construct stereopair by two photos, solves the problem that the
LiDAR system directly generates the DLG products, shortens the period of DLG production by the LiDAR
system, largely improves the practicability and the use value of the LiDAR system, and provides the base for the large-scale application of the LiDAR system in mapping,
electricity, city planning, geology and design of road and railway.
