Abstract
The invention discloses a physical dimension detection method for industrial irregularly-shaped components. The physical dimension method comprises the following steps: placing irregularly-shaped components to be detected on a rotatable lifting turntable, wherein a three-dimensional laser scanner is positioned beside the turntable, building a component design value data base and setting a target; scanning the irregularly-shaped components to obtain point cloud data of the irregularly-shaped components in any coordinate system, and matching the point cloud data; intercepting cross sections of component models, and fitting the centers and radiuses of the cross sections; comparing the coordinates of the centers and the radiuses to design values, and determining whether the error values are within an allowed error range; and choosing two centers of one of intersectant components to generate an equation of an axial line, obtaining the slope of the axial line, calculating the included angle of the axial lines of the intersectant components, comparing the included angle to the design value, and determining whether the error value is in an allowed error range. The physical dimension method provided by the invention solves the problem of physical dimension obtaining of the irregularly-shaped components, the geometric data of the irregularly-shaped components is obtained through the three-dimensional laser scanner, direct contact of the irregularly-shaped components per se is not required, and the efficiency is greatly improved compared to a conventional detection method.
