Optotrak Certus Overview

The Optotrak Certus® motion capture system offers maximum flexibility for your motion capture applications through its unsurpassed accuracy, high-speed marker frequency, portable design, and virtually wireless marker option. Built with the superior accuracy and reliability of the renowned Optotrak 3020 series, Optotrak Certus is the gold standard among research scientists.

Northern Digital Inc. specializes in designing and manufacturing research-grade motion capture systems as opposed to animation-grade motion capture systems. The Optotrak Certus is a research-grade motion capture system.

Highly Accurate and Reliable
With an accuracy of up to 0.1 mm and resolution of 0.01mm, the Optotrak Certus Motion Capture System continues to deliver the degree of precision that has become an Optotrak hallmark.

Backwards Compatible
Northern Digital Inc ensures that its existing customers can take advantage of new software and hardware features. We strive to ensure backwards compatibility of new features with previously developed systems.

Fast
A maximum marker frequency of 4600 Hz enables you to capture data at even higher speeds. In addition, the Optotrak Certus can track up to 512 markers and is pre-calibrated for fast set-up and ease of use.

Freedom from Wires
Optotrak Smart Markers, a unique inline wiring and branching technology, simplify experiment execution by providing complete freedom of movement for research subjects.

Portable
The size and weight of the Optotrak Certus makes it easy to move between locations. A wide variety of stands and mounts provide flexibility so the system can be positioned by a single person and ready for use in minutes.

Easy to Use
The Optotrak Certus is available with a range of intelligent strobers, enabling you to configure the marker activation order through provided software. For existing Optotrak 3020 users, the Optotrak Certus offers backwards compatibility so that you can enjoy many of the benefits of the new system with your existing configurations.

Research-Grade Data
The Optotrak Certus provides exceptional spatial and temporal accuracy. You can be sure that Optotrak Certus data is objective and accurate.

True Real-time Data
The Optotrak Certus delivers true real-time data 100% of the time. The exceptionally low latency of this data makes it ideal for virtual reality and other feedback applications.

No Data-Sorting
Spend research time doing research instead of data-sorting! The Optotrak Certus will NEVER misidentify or lose identity of markers. This means that time consuming and error prone manual data sorting is never required. As soon as you have collected data from your subject, you are ready to start analyzing.

No Reflections
The Optotrak Certus is not hampered by false signals created by reflections, thus there is no need for any special preparations to your lab.

Proven Reliability from NDI
First introduced in 1989, the Optotrak quickly established itself as the gold standard in accurate and reliable measurement systems for medical and human motion research.
