Bridging the Gap in Unstructured Data: Cyclone REGISTER 360 vs. CORE

这是一系列专注于带来的专家见解的第二个旋风注册360into alignment with the popular toolset of Cyclone CORE. Please refer back to thefirst in this serieson UCS and Control for more information.

This expert insight will focus on the gaps that exist in the realm of unstructured data support—an increasingly important topic as Leica Geosystems offers more autonomous solutions based on mobile sensor platforms, including theBLK2GO, BLK ARC and BLK2FLY。

Unstructured data is data without a regular row, column grid. All mobile data and LGS data is unstructured whereas all data collected by static scanners (i.e.RTC360，，，，BLK360，，，，P系列) is structured with the data in row column format.

使用2022版本，Cyclone寄存器360将支持Cyclone Core支持的所有非结构化数据类型。这不仅仅是支持新传感器，还包括流行的LGS格式和第三方非结构化格式，LAS，非结构化E57，PTS等。

The addition of these unstructured data formats supports users who are branching into these autonomous solutions and ensures that users can round trip data through Cyclone REGISTER 360, meaning that files they receive from collaborators can be integrated with newly imported sensor data and combined into a single project. Likewise, it offers users the ability to take in these unstructured formats and push them through the Leica Geosystems downstream workflow by publishing them as LGS, opening them directly inCloudWorxor creating a newCyclone ENTERPRISEproject with the data which provides a pathway to CloudWorx,Cyclone 3DR，，，，Map360and thePowered by JetStreamfamily of products.

对某些行业来说,非结构化数据是future of laser scanning. As these autonomous solutions continue to improve and gain traction in those industries, the model of continuous scanning could fully replace static scanning. It allows users to capture a larger area more quickly. However, it still has its drawbacks—lower accuracy and data fidelity are still being worked through and remain an area of concern for industries that have a longer record of integrating laser scanning and for whom accuracy is paramount.

随着移动传感器数据的改善，它已在扇区中被接受where historically, only structured data was used. From plant and processing to BIM, civil survey, and other non-standard industries like movie production, GIS and city planning, unstructured data is becoming more and more common in standard deliverables. Because of the potentially large areas scanned, the need to register 100’s of static scans versus far fewer unstructured scans, is a huge advantage in time-saving in the field and the office.

And it’s not only Leica’s mobile solutions that are shaking up the 3D Scanning world—third-party mobile scanners are cropping up, and Leica Cyclone products remain the best solution for those seeking to fuse data from different sensors and different manufacturers. It is important that we continue to provide a solution for both experienced and new users to leverage the benefits of sensor fusion.

To that end, Cyclone REGISTER 360 2022.0.0 will support the following unstructured data formats and post-import tools to facilitate the use of unstructured data:

• Import of BLK2GO data
• blk2fly数据的导入
• Import of BLK ARC data
• Import of Pegasus MMS data
• Import of unstructured PTS
• Import of TXT
• Import/Export of unstructured E57
• 非结构化RCP的导入 /导出
• Import/Export of LAS
• Import/Export of LGS (including those without Normals)
• WayPoint creation post-import
• Enhanced Suggested link creation
• Link creation criteria

New Format Support

这些新格式的添加可能对用户具有广泛的影响。传统上，Cyclone Core是所有数据，从任何扫描仪，任何来源的所有数据都可以合并的地方，这对于Cyclone寄存器360来说现在是正确的，这意味着用户可以利用智能自动化和旋风的现代UI，而现代的UI则是传统上可以在Cyclone Core中找到强大的格式支持。特别是，添加非结构化的E57（最受欢迎的中性点云格式）意味着，几乎任何第三方产品中的任何数据都可以导入到旋风寄存器360中，并以其他数据注册，并以中性格式或以中性格式发布。specifically into Leica’s downstream workflow.

用户开始导入非结构化数据时，有几件事应注意。Be aware that Auto Cloud, Auto Target and Auto Sphere import options are not supported for unstructured data. Unstructured data imports containing a large number of points can also take longer to import than a structured data set of the same point count.

Adding these features and functions was informed by the tools that are already available inside of Cyclone CORE.

LGS was the first unstructured format supported by Cyclone REGISTER 360. As a Leica-native format, it is an area that we have continued to improve and advance over the years. This release introduces some improvements to the way that LGS files are handled. LGS import time has been improved by not processing all WayPoints for registration upon import. This greatly speeds up import. If, after import, a user selects a WayPoint to register with, that WayPoint will be processed as it enters Visual Alignment. This ensures that unused WayPoints are not processed unnecessarily, consuming valuable time and increasing the size of the project.

WayPoint Creation Post Import

The ability to create WayPoints—or pseudo-Setup positions—replicates the features in Cyclone CORE known as插入相机and插入相机高度。A WayPoint (or inserted Camera) is a synthetic Setup that only contains a position and associated imagery generated from that position upon creation. Because a WayPoint is generated from the scan data, it doesn’t contain a traditional pano; instead, it contains a pano of the scan data.

When the BLK2GO was introduced, Cyclone REGISTER 360 added the ability to create WayPoints along the trajectory of the Walk at a set interval as part of the import process. Now, however, users can create additional WayPoints anywhere within their project—not just on the trajectory. This functionality is available for any project (structured or unstructured), allowing users to scale up the navigability of their data set without increasing the project size.

在很多方面,它是相似可以测量的pano, add GeoTags or Snapshots and jump to other Setup/WayPoint positions in downstream applications. WayPoints support easy navigation within a mobile sensor dataset. You can jump between them as you would Setups and you can create Snapshots from them within TruView. However, because these inserted WayPoints may be far from the actual capture location, it is important to consider that they may have sparser data and a greater error than those which are on the trajectory or close to a Setup.

Suggested Links and Link Creation Criteria

In Cyclone REGISTER 360 2022.0.0, users can addup to 5000 suggested links per Bundle (up from 500). Suggested links are a graphical way to draw attention to possible additional links in a Bundle. Once the command is used, dashed white lines appear within the Bundle. Adding additional links tightens a Bundle making it more rigid and accurate. Users of Cyclone CORE will be familiar with the concept of adding links known as constraints in Cyclone CORE.

Unlike in Cyclone CORE, however, Cyclone REGISTER 360 offers advanced Link Creation Criteria that give the user a great deal of control over the quality of the links created没有having to QA each link manually. A user can set minimum cloud-to-cloud error and minimum overlap per link. By default, Link creation Criteria is set to 12mm or ~.5 inch for cloud-to-cloud and 20% for minimum overlap, but this can be adjusted from within the Settings. Any links created by this feature must meet the link criteria, or the link is not created, thereby ensuring that only links meeting the user’s minimum quality criteria are used in the Bundle. Users can opt to override these settings during Visual Alignment on a link-by-link basis.

Conclusion

With the improvements to Cyclone REGISTER 360 to improve its handling of UCS’ and Control and now support for unstructured data, the gaps between Cyclone CORE and Cyclone REGISTER 360 has dramatically shrunk. There remain a few key areas of improvement that will be tackled over the next major releases that will result in full, functional parity of the products and allow all users to make the switch to the next generation Cyclone REGISTER 360. These improvements include support for even larger projects, resection and traverse support for those who rely upon DAC-equipped scanners for their survey workflows, and a global constraint list to support users who rely heavily upon targets.
