Moving toward feature parity of Leica Cyclone CORE and Leica Cyclone REGISTER 360

User Coordinate System (UCS) and Control

Leica Cyclone REGISTER 360 - USC & Control

This is the first in a series of expert insights focused on bringing Cyclone REGISTER 360 into alignment with the popular toolset of Cyclone CORE. The second in this series focuses on the gaps that exist in the realm of unstructured data support.

Leica Cyclone REGISTER 360 was released in 2017, originally as a companion to the Leica RTC360 3D Reality Capture Solution. Since that time, it has become the registration product of choice for both new users joining the world of reality capture, as well as a significant portion of our legacy users who first began working with reality capture data in Leica Cyclone REGISTER (CORE). Nevertheless, Cyclone CORE has remained an integral part of many users’ workflow due to its unparalleled ability to handle massive datasets and complex registrations.

Over the last four years, Cyclone REGISTER 360 has come a long way from its original feature set and the gap that exists between the two products is shrinking rapidly. In this expert insight, I discuss some of the recent improvements made in Cyclone REGISTER 360 that are closing the gap between Cyclone CORE and Cyclone REGISTER 360 as well as some improvements that you can look forward to in future releases.

The majority of users find the simple User Coordinate System (UCS) and Control features of Cyclone REGISTER 360 to be sufficient, however users who need support of the Traverse workflow, or more flexibility of target section and application, find Cyclone CORE is the better choice. For professional surveyors the need for more comprehensive tools demands the advanced tools of Cyclone CORE, whereas the georeferencing tools in Cyclone REGISTER 360 work well for rotating a single bundle on Control or setting a local UCS on a bundle, for example in the case of a plant or other facility.

Cyclone CORE remains the gold standard for both UCS and Control features. offering survey-grade control leveraging all available functions on Leica Geosystems scanners (DAC, traverse etc.). By design, the UCS and Control feature set in Cyclone REGISTER 360 are much simpler. Cyclone REGISTER 360 has the ability to apply georeferencing to a group or bundle of setups or individual setups. This is achieved by importing a text file that is pre-formatted with at least three coordinates that correspond to targets in a setup/bundle.

Cyclone REGISTER 360 also has the ability to apply a UCS to a setup or bundle. Setting Z level combined with setting X axis or Y axis allows the users to apply the desired UCS in most cases. Setting Z level is supported by forming a ground plane and then setting the Z axis or “Up Direction” per setup. Setting the X or Y axis can be achieved by creating a plane on a wall or by using the corner plane creator as shown in image 3.

Image 3: here the X and Y axis is created by selecting a corner which defines three intersecting planes.

With the 2020.1 release of Cyclone REGISTER 360, we have introduced several features that will allow Cyclone REGISTER 360 to supplant Cyclone CORE for more advanced UCS and Control workflows. All of the below features are designed to bring existing Cyclone CORE features into Cyclone REGISTER 360 while preserving the simplicity of the software. These include:

Georeferencing features:

  • Apply control to single setup or Leica BLK2GO walk:
    This feature allows the application of Control to a single setup or walk. Previously, at least two setups or walks were required.
  • Use of multiple Control files:
    Now multiple Control files can be imported and used, allowing for multiple coordinate systems in a project.
  • Snap to control in SiteMap:
    Now all setups and bundles imported into Cyclone REGISTER 360 will snap to a Y up or north orientation in the SiteMap and 3D top ortho view.
  • Align bundle to control without labels in bundle (match with geometry of targets):
    Target labels, in setups or bundles, are no longer necessary when applying control. The relationship is calculated automatically using geometry matching.

UCS features:

  • Set Level or the Z axis by plane:
    This feature allows the user to create a plane on a floor or flat surface and set the “up” direction or Z axis thereby establishing level for a Setup or Bundle.

  • Set UCS by plane:
    The user can create a plane on a wall and set either the X or Y Axis.

  • Set UCS by pic:
    Allows the user to pick any point cloud point and enter the desired coordinates to transform the bundle or Setup.

  • Set UCS pick and plane, by pick and corner
  • Create a UCS in Cloud Viewer:
    Allow the user to set a UCS from a 3D view of the point cloud. Previously only 2D view and UCS creation was allowed.

  • Region grow corner for identification of room corners to assign coordinates:
    Allows the user to automatically create corner planes and establish a corner coordinate for UCS creation.

  • Easy-to-use dialog for UCS creation:
    Guided workflow dialog for easier operation of the new UCS features.

Future releases will see further improvements to these two workflows including flexible control file import, setting UCS by selection of Targets, setting UCS by line creation (i.e. line drawn on the bottom of a wall) and applying control using target heights.

The goal of adding these features to Cyclone REGISTER 360 is to reach complete parity between Cyclone REGISTER 360 and Cyclone CORE to support established users in making the switch but also to introduce new users to the powerful benefits that these advanced features can have on their accuracy and efficiency. Cyclone REGISTER 360, while more powerful in visual registration and import, still needs to be updated with all the relevant features in Cyclone CORE to give our customers flexibility but still maintain ease of use. We are committed to reaching the stage of feature parity in the coming years in order to bring all users over to our next generation products and focus all of our development efforts on Cyclone REGISTER 360.

Many current Cyclone REGISTER 360 users may believe that advanced UCS and Control workflows are unnecessary for their work, however we believe that all users can benefit from these tools.

Using georeferencing allows for the transformation of the 3D coordinates in a registration. Applications include locating the registration on a virtual globe (similar to Google earth), or combining a registration with another set of data that is also in real world coordinates, likewise, georeferenced data supports many plant and manufacturing environment applications where it is vital to match coordinates systems between point clouds and 3D models.

Advanced UCS tools provide an easy way to create an alternate coordinate system. Applications include making the building or plant square to the screen for line drawing in CAD, matching to plant or building coordinate systems, and creating multiple UCS’s to help with modeling in third-party software.

Despite the great strides that Cyclone REGISTER 360 has made in the last releases to close the gap with Cyclone CORE, there remain key differences that must be addressed before complete parity can be achieved.

The scale of projects that Cyclone REGISTER 360 will continue to be improved. As of the 2021.0.0 release, Cyclone REGISTER 360 can handily work with projects up to 2,000 setups. The objective is to reach support for up to 5,000 setups per project. In a similar vein, referencing projects together without having to merge them will allow for large data handling while preserving the usability of Cyclone REGISTER 360.

Support for new laser scanners and new formats will remain a key focus of Cyclone REGISTER 360 development with an eye towards support unstructured data formats for mobile scanning. LAS and other ASCII formatted point clouds will be supported. In parallel, improvements to import speeds will be pursued.

Likewise, additional export formats and speed improvements will be seen on the downstream side of the Cyclone REGISTER 360 workflow.

As Cyclone REGISTER 360 gains features, however, its ease of use cannot be compromised. We are committed not only to transferring tools from Cyclone CORE to Cyclone REGISTER 360, but to improve their usability by harnessing smart automation where possible and relying upon guided workflows and wizard-based dialogs where automation is not possible.
