Applications using Photogrammetry and Lidar
Ship-to-Shore cranes are essential in container terminals for loading and unloading ships. The breakdown of a crane creates problems in the logistics chain, resulting in operational losses and fines. It is crucial to ensure that cranes are regularly inspected and maintained to ensure safety and efficiency. In this blog, we will take a closer look at the new applications of 3D modeling, particularly photogrammetry and lidar, and how these technologies can transform standard crane inspections.
The History of Traditional Crane Inspections
Traditional methods for crane inspections often rely on visual inspections by human inspectors. This is mainly done through human entry, rope techniques, and the use of aerial lifts for hard-to-reach places. While essential, this process can be unsafe, time-consuming, and expensive, depending on the inspector’s knowledge. Moreover, there is always the risk of human errors, leading to the oversight of defects at times.
Photogrammetry and Lidar 3D Modeling
This blog focuses on the use of 3D modeling for Ship-to-Shore (STS) harbor cranes using photogrammetric and lidar models. A photogrammetric model can add value to annotating and locating errors on an STS crane. A lidar model, on the other hand, can be used to precisely measure the crane with high precision. By combining the two models, a CAD model can be created, from which CAD drawings can be generated. Both models work together to form a powerful tool for viewing and analyzing the crane from various angles. If desired, the model can even be placed in a virtual environment, allowing you to ‘fly’ around the crane.
Several companies have successfully integrated 3D modeling into their crane inspection processes, using photogrammetry and lidar to create a detailed image of the crane. This technological approach not only enhances the accuracy of inspections but also provides a more efficient and cost-effective method. Moreover, these models can be integrated into our asset inspection platform I-Spect.
Benefits of 3D Modeling
Companies can eliminate the limitations of conventional inspection methods by using 3D modeling techniques. It not only enables inspectors to obtain detailed visualizations of the crane but also allows for remote inspections in the future by navigating virtually through the crane from their office environment, with or without a VR headset.
The creative ways in which 3D modeling is combined with lidar and photogrammetry mark a significant breakthrough in crane inspection technology. These technological advancements revolutionize how we maintain and inspect cranes, improving efficiency and accuracy. This approach seems to be a positive step towards ensuring the reliability of cranes in container terminals.
