Abstract

The invention discloses a system and method for rapidly measuring the characteristic parameter of the hub of a wind power generation device. The system is composed of an annular track, a multi-degree-of-freedom mechanical arm, an optical measuring head and a projection light source. The measured hub is arranged in the central area of the annular track. The multi-degree-of-freedom mechanical arm and the projection light source are mounted on the annular track through a base. The optical measuring head is mounted at the end of the multi-degree-of-freedom mechanical arm. The mechanical arm can perform circular motion around the hub on the track through the base. The system is based on the active three-dimensional measurement technology, performs optical measurement by means of the combination of the projection light source and the measuring head, may rapidly acquire the characteristic parameter of hub morphology in combination with the multi-degree-of-freedom motion of the mechanical arm, and has a high degree of automation and high measurement efficiency.

Description

technical field [0001] The invention relates to the field of measuring characteristic parameters of objects, in particular to a system and method for quickly measuring characteristic parameters of hubs of wind power generation equipment. Background technique [0002] With the development of science and technology and industry, the application of 3D measurement technology in automatic production, quality control, robot vision, reverse engineering, CAD / CAM and biomedical engineering has become increasingly important. The traditional contact measurement technology has limitations such as long measurement time, the need to compensate the probe radius, and the inability to measure elastic or brittle materials, so it cannot meet the needs of modern industrial development. It generally has the following disadvantages: [0003] (1) The operator uses the feeling of the hand to ensure the contact pressure between the probe and the workpiece during measurement, which often varies from...
