Zusammenfassung:The invention discloses a countersinking parameter detection method and system, and the method comprises the steps: scanning a countersinking workpiece through employing a line laser and zoom microtechnology, and obtaining the three-dimensional point cloud data of the countersinking of the workpiece; filtering and splicing the collected point cloud data to obtain a point cloud comprising a countersink upper surface, a countersink conical surface and a countersink cylindrical surface; fitting the point clouds of the conical surface and the upper surface to obtain a curved surface equation, and solving an equation set of simultaneous countersinking conical surface equation and upper surface equation to obtain an intersecting line of the upper surface and the countersinking conical surface, namely an outer hole contour; fitting the outline of the outer hole to obtain a plane equation and the radius of the outer hole; fitting the countersink cylindrical surface to obtain a curved surface equation, and solving an
