Markerless Capture, Built Into Your Nexus Workflow

Nexus Markerless is motion capture software that tracks human movement without attaching markers to the subject. It uses computer vision and machine learning models to track body segments and joints, and it works within the Vicon Nexus ecosystem alongside marker-based capture, digital force plates and object tracking. You can run markerless and marker-based capture together with force plates in a single workflow, giving you richer, more integrated data from every session. Real-time visualisation lets you check data quality as it's being captured, so you can be confident in your results before your subject leaves the lab and spend less time on post-processing. Transparent keypoint data shows exactly which points were tracked to build each skeleton, with no black-box outputs, and you can export the underlying data to analyse, adapt or run through your own scripts.

Nexus Markerless is a separate product that works within the Vicon Nexus ecosystem. Nexus Markerless data is processed in Nexus 2.21 and flows directly into your existing Nexus workflows and reporting tools, so you can add markerless capture without changing how your lab already works. Because both run in the same ecosystem, you can capture markerless and marker-based data in the same session and compare the outputs side by side. Markerless capture uses Vanguard, Vicon's first camera designed for markerless motion capture, and works alongside your existing optical cameras, digital force plates, and object tracking.

Nexus Markerless supports simultaneous hybrid capture by design when bought with an optical system. This allows labs to compare both outputs directly on the same trial, blend methodologies for different subjects, and validate markerless results against their existing marker-based data without a separate capture. 

Nexus Markerless requires Vicon Vanguard cameras and Vicon Nexus 2.21 onwards. Vanguard is Vicon's first camera designed specifically for markerless motion capture. Markerless captures simultaneously with Vicon optical cameras for marker-based tracking of subjects and objects, and force plates for synchronized kinetic data, with everything captured through the same Nexus session. 

 Yes. Nexus Markerless supports synchronised capture with force plates in the same session as markerless and marker-based tracking. This gives labs multi-modal data, kinematics and kinetics together,  without running separate captures or reconciling data from different systems afterwards.  

 Yes. Nexus Markerless provides real-time visualization, so data can be viewed as it is captured. Operators can verify capture quality before the subject leaves the lab, which reduces failed trials and cuts post-processing time. This matters most for teams running high volumes of subjects or teaching sessions with limited lab time.

 Yes. Nexus Markerless exposes the underlying keypoint data rather than returning a processed output only. Keypoints can be exported, manipulated, and run through a lab's own scripts. This transparency lets researchers validate their own findings and interrogate the data behind a result, rather than accepting outputs they cannot inspect. 

Nexus Markerless is built for clinical and academic teams who need to capture data quickly and at volume. Typical users include biomechanics researchers, university teaching labs running student classes, and sports performance institutes needing high subject throughput. It suits teams prioritizing volume of data and speed of capture within their existing Vicon workflow. 

No, but you will need Nexus Markerless hardware and software to be operational. Nexus Markerless is natively integrated into Nexus, so markerless data enters the same processing and reporting workflows that a lab already uses.
