使用Riegl VMX-250移動激光掃描系統進行精確的長隧道測量(中文6000字,英文4200字,英文PDF)
摘要
自2010年7月以來, 我們公司一直在不同的場景中使用 RIEGL VMX-250, 尤其是在與數據采集效率相關的情況下。在本演示中, 我們將介紹一個長隧道測量項目。
西班牙擁有歐洲最長的高速鐵路網絡。最近, 修建了兩條25公里長的平行隧道, 西班牙當局要求進行準確的三維調查。Artescan 使用 RIEGL VMX-250 完成了這項調查。集成的 INS-GNSS 是為1分鐘的全球定位系統故障指定的;然而, 在這種情況下, 每個調查項目都是在移動接收機中總 GPS 停機約1小時的情況下實現的。通過結合在隧道內獲得的外部 GPS 定位、INS 和里程表測量儀, 實現了2厘米的絕對精度。對于軌跡調整, RiProcess 功能強大的工具被成功地使用。

Precise Long Tunnel Survey using the Riegl VMX-250 Mobile Laser Scanning System
ABSTRACT
Our company has been using the RIEGL VMX-250 since July 2010 in diverse scenarios, especially where data acquisition productivity is pertinent. In this presentation, we will be describing a long tunnel survey project.
Spain has the longest high speed rail network in Europe. Recently, two parallel 25 km long tunnels were built and an accurate 3D survey was demanded by the Spanish authorities.Artescan accomplished this survey using the RIEGL VMX-250. The integrated INS-GNSS is specified for 1 minute GPS outages; however, in this case, each survey project was realized with approximately 1 hour of total GPS outage in the mobile receiver. An absolute accuracy of 2 cm was achieved by using a combination of well acquired exterior GPS positioning, INS and odometer measures inside the tunnel and use of control points. For trajectory adjustment, RiProcess powerful tools were successfully used.
