AI Technical Summary
Existing technologies make it difficult to effectively identify and segment cable accessories, leading to difficulties in detecting quality parameters during cable laying and hindering reasonable control over cable accessory levels.
A method based on 3D point cloud was adopted. The 3D point cloud data was split twice, and the cable point cloud data was collected by a laser scanner. The quality parameters of the cable accessories were extracted by combining coordinate system establishment, preprocessing, primary segmentation and secondary segmentation algorithms.
It enables accurate identification and segmentation of cable accessories, assisting construction and acceptance personnel in conducting efficient and accurate analysis of cable laying location information and quality verification, reducing engineering construction risks, and improving cable safety and construction quality.
