The uGPS Rapid Mapper from Peck Tech Consulting Ltd. is a new system composed of a laser scanner mounted at the front or on the back of a mining vehicle, which acquires 3D images in underground mines. A detailed map of the mine, with its various tunnels and ramps, is gradually constructed as the vehicle travels through the underground environment. Clients use this map for mine design (to plan ventilation systems, for example), operation monitoring, and production planning. The company wants to add value to the images acquired by the uGPS Rapid Mapper. In this research project, the images will be by processed to reveal geological information. Software will be developed to calculate the orientation of fractures in the tunnel walls. This information is critical to plan support for tunnels. The software will also be capable of calculating the roughness of rock faces. Variations in roughness might help to distinguish between different rock types and to build a basic geological map of the mine. Finally, since the uGPS Rapid Mapper measures the brightness of the laser beam reflected off the tunnel walls, the software will identify zones of higher reflectivity. These zones might correspond to areas where there is a higher concentration of metallic minerals of economic interest. The project includes field work in an underground mine to test how the laser scanner should be mounted on the mining vehicle and at what speed the vehicle should be driven to get the best quality images for automatic geological mapping. The main challenge will to acquire images at a resolution high enough to capture fine structural details and small bright areas, even in the presence of dust. The main deliverable of the project will be recommendations to upgrade the current uGPS Rapid Mapper system for this application in a later generation of the product.

Peck Tech Consulting Ltd.的uGPS快速测图仪是由安装在采矿车辆前部或后部的激光扫描仪组成的一种新系统，用于获取地下矿山的三维图像。随着车辆在地下环境中行驶，矿场的详细地图以及各种隧道和坡道将逐渐构建起来。客户使用该地图进行矿井设计(例如，规划通风系统)、操作监控和生产计划。该公司希望为uGPS快速映射器获取的图像增值。在本研究项目中，将对图像进行处理以揭示地质信息。将开发软件来计算隧道壁上裂缝的方向。这些信息对于规划隧道的支持至关重要。该软件还将能够计算岩石表面的粗糙度。粗糙度的变化可能有助于区分不同的岩石类型，并建立矿山的基本地质图。最后，由于uGPS快速测图仪测量隧道墙壁上反射的激光的亮度，该软件将识别出反射率较高的区域。这些区域可能对应于具有经济价值的金属矿物较集中的地区。 该项目包括在地下矿山进行实地工作，以测试激光扫描仪应该如何安装在采矿车辆上，以及车辆应该以多快的速度行驶，以获得用于自动地质制图的最佳质量图像。主要的挑战是以足够高的分辨率获取图像，以捕捉精细的结构细节和微小的明亮区域，即使在存在尘埃的情况下也是如此。该项目的主要成果将是在该产品的下一代产品中为这一应用升级目前的uGPS快速测绘系统的建议。
