摘要

在过去的几年里，hydro - quamesbec公司开发了一种高精度的液压门架激光扫描测量系统。受第一个设计的启发，开发了一个新的紧凑和低成本的平台。WireScan技术实际上适用于测量任何垂直和水下结构的几何形状。通过对激光扫描仪定位算法的改进，进一步扩展了该技术的适用性。利用通用图形处理单元的新计算能力，提高了该算法对海洋雪的鲁棒性。介绍了四个与水电站(进水口和溢洪道闸板)和通航船闸(平衡闸门和航道宽度)相关的案例。

A new compact solution for the rapid measurement of underwater gate guides

In the past years, a laser scanning system to measure hydraulic gate frames with high precision was developed by Hydro-Québec. Inspired by this first design, a new compact and lower cost platform was developed. The WireScan technology is actually applicable to measure the geometry of any structure that is vertical and underwater. The applicability of this technology was further extended with improvements to the localization algorithm of the laser scanner. Its robustness to marine snow was increased by taking advantage of the newly available computing power of general purpose graphical processing units. Four case study related to hydro plant (water intake gate and spillway stoplogs), and navigation locks (balancing gates and channel width) are presented.
