The invention relates to the technical field of
computer vision, in particular to a
station platform limit intelligent detection method and
system based on
computer vision, and the method comprises the following steps: obtaining platform region
spectral data, extracting spectral features according to the
reflectivity value of each pixel point in a spectral range, comparing the spectral features with the features of various known materials, and determining the position of the
station platform limit. And identifying material types of the plurality of positions, detecting obstacles, and generating
material classification feature values. According to the method, the
spectral data is acquired, the
reflectivity value is compared to identify the
material type, the
texture feature and the gradient change rate are utilized to analyze and identify the fuzzy area, misjudgment on the
fuzzy identification is reduced,
point cloud data and image information are adopted for time-space synchronous registration, and multi-source sensing information is fused to enhance the time-space consistency of three-dimensional reconstruction. The size accuracy of the
platform model is improved, the space offset is calculated by comparing
engineering design drawing data, a structure deviation quantitative
evaluation system is established, a deformation area is positioned, and the foreseeability of safety early warning is improved.
