  • Oil tank measurement method and system based on laser point cloud analysis
    Patent number: 11333541
    Abstract: The invention provides an oil tank measurement method and system based on laser point cloud analysis, comprising: acquiring point cloud data inside an oil tank, which is collected by a laser measurement device; separating point cloud data of a main body of the oil tank from point cloud data of a plug, to acquire the point cloud data of the main body of the oil tank; calculating, based on Gauss mapping, an axis for the point cloud data of the main body of the oil tank; determining any one first plane perpendicular to the axis, and projecting a point cloud of the main body onto the first plane to obtain a point cloud of a projected cross-section of the tank body on the first plane; multi-segment fitting the point cloud of the projected cross-section of the tank body; and calculating a volume according to a result of multi-segment fitting.
