As a new type of surface measurement technology, 3D laser scanning technology is another technological innovation after GPS technology in the field of surveying and mapping.
This time for a landslide area in Beijing, Tuojiafeng Sheng 3D laser product special dealer Beijing Jinyun Technology Co., Ltd., using Topcon GLS-2000 3D laser scanning data collection work in the summer of 2015, and for multiple acquisitions The landslide body data is analyzed to summarize the displacement of the landslide body caused by the landslide saturation under strong rainfall.
Topcon GLS-2000 3D laser scanning technology features
Short range (130 meters) / medium distance (350 meters) / long distance (500 meters) three range modes available Full view angle (H360 ° * V270 °) scanning capability Dual lens (telephoto / wide angle) five hundred 10,000-pixel camera five optional scanning mode (fast / high-definition / security / long distance / fine)
Airborne / post-processing software all Chinese display, color LCD 720P display Topcon / Suojia total station universal battery, support hot plug high precision "Precise Scan Technology II" noise reduction technology, the world's first automatic measuring instrument High-function traverse scanning method, scanning prism
Summary of results of landslide hazard monitoring project
When establishing a control point on the opposite side of the landslide body, the stable bedrock is selected and the control point is set using stainless steel material. The Topcon GLS-2000 3D laser scanner is erected at the known control point when scanning the landslide body, ensuring the mandatory pair. The mid-simultaneous scanner has a back-viewing function, so it ensures that each period of data does not need to be spliced ​​by point cloud data, and the scanning density and scanning range are set in the same coordinate system to perform point cloud data acquisition.
Landslide body point cloud data
Through manual and simple monitoring, the crack deformation of the trailing edge of the landslide within 6 days is 28mm and 66mm. At the same time, using the Topcon GLS-2000 3D laser scanner on July 25th and August 1st, two-phase laser scanning measurements were carried out on the landslide body. Through the comparison and analysis of the data in the second phase, it was found that there was obvious displacement of the landslide body within 7 days. Deformation, the maximum deformation is about 600mm.
