Pipeline section contour acquisition method and device, electronic equipment and storage medium

Abstract

The invention provides a pipeline section contour acquisition method and device, electronic equipment and a storage medium The method comprises the steps of determining a first coordinate value of each contour point in a radar coordinate system based on the original data, collected by a radar, of a pipeline section contour point, determining a radar coordinate value of the radar in the pipeline coordinate system, and converting the first coordinate value of each contour point into a second coordinate value in the pipeline coordinate system based on the radar coordinate value, determining the distance from the corresponding contour point to the circle center of the pipeline section according to the second coordinate value so as to obtain the measurement radius corresponding to each contour point, and if the measurement radius corresponding to any contour point is within a preset range, taking the corresponding second coordinate value as effective data, and carrying out data fitting on all the effective data to obtain a pipeline section contour. According to the method, the pipeline coordinate point data corresponding to the pipeline branch pipe and the convex-concave part of the pipeline can be filtered out, and then data fitting can be accurately carried out on all effective data to obtain the section contour of the pipeline.

Description

technical field [0001] The present invention relates to the technical field of pipeline measurement, in particular to a method, device, electronic equipment and storage medium for acquiring a pipeline cross-sectional profile. Background technique [0002] At present, in the process of obtaining the cross-sectional profile of a pipe based on two-dimensional laser scanning, the usual method is to receive the echo signal of the same frame of laser signals, and obtain the cross-sectional profile of the pipe according to the echo signal. However, the profile obtained by the two-dimensional laser radar is obtained by fitting the data corresponding to all the collected echo signals. Since there are branch pipes, convexities, etc. The center and radius of the circle are offset. Contents of the invention [0003] The present invention provides a method, device, electronic equipment and storage medium for obtaining a pipeline cross-sectional profile, which are used to solve the def...
