|3‐Dimensional As‐Built Drawing of Underground Pipeline Buried Project
This method cites the characteristics of close-range photogrammetry technology, multi-view stereo visual 3D(3-Dimension) reconstruction technology, to reconstruct 3D scenes from the structure from motion(SfM) recovery structure algorithm. The design uses a non-metric camera to measure the current situation of the trench when the underground pipeline is buried. The high overlap image (80%) is used to reconstruct the 3D model to record the new and existing underground pipelines inside the trench. There have real-world spatial locations of various pipelines, and the results are in 3DPDF format. The 3D model can be visually browsed, measured, marked, and annotated on the internationally available and free Adobe PDF reader platform. After the 3D model has spatial position coordinates and inserting the GIS platform , in addition to digitizing the newly set pipeline x, y, z coordinates, the existing pipelines in the trench are also collected together, and compared with the corresponding pipelines in the vector database for comparison analysis and correction. Fix its spatial position to the correct position.
The test results of 50 work areas in the test area of Taichung City and Kaohsiung City show that the check point error of the model is less than 20 cm, and the measurement accuracy of the depth, width and length of the burying can reach 5 cm, which is in line with the standard of underground pipeline database and the accuracy requirements of the institutional norms. Therefore, it can be used as the basis for the acceptance of underground pipeline burying projects, which is sufficient to replace the as-built drawings of traditional paper and vector drawings. The pipeline depth indication is no longer a passive display of the limited picture photos, but a visual and multi-angle dynamic 3D model operation.
