We are pleased to announce a new automated workflow for mobile convergence monitoring, which allows for the simple comparison of two or more uGPS Rapid Mapper™ scans.
It is with immense pleasure that we announce the release of the latest uGPS Rapid Mapper™ automated workflow for mobile convergence monitoring. This new process allows for automated comparison of two or more uGPS Rapid Mapper™ scans, with only a few mouse clicks. Utilizing our existing and proven target alignment method, released in early 2017, this new software tool can automatically georeference, align, and compare multiple scans from an identical area but taken at different dates. This eliminates the need to manually align scans, allowing for hundreds of metres of drifts to be analysed for convergence all at once– done automatically and much faster than conventional/manual methods. The uGPS Rapid Mapper™ scan pattern provides complete coverage of the area in question, allowing area-to-area movement comparisons rather than merely point-to-point measurements common to conventional methods. The workflow goes as follows:
- Scan the area where convergence is expected.
- Scan the same area after waiting for some convergence to have occurred. The system can reliably detect 30 mm of movement.
- Use the target alignment to convert the first scan to create a reference data set.
- Convert the second scan, using the first scan as the reference, to automatically align the two point clouds and generate the convergence monitoring outputs, listed below.
- That’s it! Open your aligned point cloud with completed convergence measurement for analysis in your desired point cloud manipulation software. See this link for our recommended software list.
This workflow can create up to four different outputs for analysis: a text report and three types of point clouds. Each point cloud contains attributes based on the calculations completed during processing. These outputs have been developed with close input from our industry partners– with a focus on generating useful information for quick decision-making, rather than reams of cumbersome data.
This new workflow, developed with industry partners, helps our customers realize the important benefits of mobile scanning for convergence monitoring. Allowing for large areas of operational block cave mines to be monitored regularly without disrupting production, the value proposition is clear: hours of time saved in monitoring and data processing, reduced human exposure in potentially unstable areas, and much higher-quality data.
