Abstract

The invention relates to a method for measuring the space size of a hydraulic pipeline. According to the method, the actual surface of the measured hydraulic pipeline is converted into a point cloud by utilizing a photographing type three-dimensional scanner, then a hydraulic pipeline space model is constructed based on the point cloud, and finally geometric measurement is performed on the hydraulic pipeline space model so that the space size of the measured hydraulic pipeline is obtained. A new reliable measurement means is provided for controlling the geometric forming quality of the hydraulic pipeline so that the measurement accuracy of the space size of the hydraulic pipeline can be guaranteed, and the measurement efficiency of the hydraulic pipeline can also be enhanced. Meanwhile, the provided method for measuring the space size of the hydraulic pipeline based on three-dimensional scanning is a flexible method, and arrangement of multiple measuring tools is not required so that measurement for the size of the hydraulic pipelines of various pipe diameters can be supported.

Description

technical field [0001] The invention relates to the technical field of space dimension measurement methods, in particular to a method for measuring the space dimension of hydraulic pipelines. Background technique [0002] As an important part of the hydraulic system, the hydraulic pipeline's space size will directly affect the reliability of the hydraulic system installation. After the hydraulic pipeline is manufactured and formed, it is necessary to measure the space size of the hydraulic pipeline to ensure that the length deviation of each straight section of the hydraulic pipeline and the angle deviation of the bent section are within the allowable range. At the same time, in the process of research and development of the hydraulic system of complex products, according to the layout of the hydraulic system, it is necessary to first obtain the pipeline sample by manual bending, and then use the measured size of the pipeline sample to write the Forming code to realize auto...
