Abstract

The invention discloses a method for measuring the diameter of an embedded sleeve of a track plate, and belongs to the technical field of track safety. The method comprises the following steps: establishing a coordinate system of the track plate through a binocular stereoscopic vision module and a line structured light scanning module to obtain point cloud data of the track plate; segmenting pointcloud data around the pre-embedded sleeve from the point cloud data of the track plate; preprocessing the point cloud data around the pre-embedded sleeve, finding out the circle and radius of the pre-embedded sleeve by using a least square method, and determining the diameter of the pre-embedded sleeve. According to the method for obtaining the point cloud data of the embedded sleeve of the trackplate by using the binocular stereoscopic vision module and the line structured light module, when feature extraction and matching point registration are carried out, wrong point cloud data at the edge of the embedded sleeve can be effectively removed, convenience is provided for subsequent data processing, and the measurement accuracy is improved.

Description

Technical field [0001] The invention relates to the technical field of track safety, in particular to a method for measuring the diameter of a track plate embedded casing. Background technique [0002] With the rapid development of the times, various technologies applied to high-speed railways in China have achieved world-renowned achievements, and have achieved an industry-leading position in the world. Thanks to the country’s massive support for high-speed railway construction, high-speed railways have become The main artery of the national economy, the ballastless track slab used in high-speed railway is one of the key technologies of high-speed railway technology. The track slab is the foundation of the bearing track and plays an important role in ensuring the safe and stable operation of trains. It is different from the sleeper system of ordinary railways. The track slabs used in railways have strict requirements. The embedded casing is a section of plastic casing with good...
