New MoCap Cameras Maximize Accuracy at Long Range

The new Primeˣ 120 and Slimˣ 120 cameras feature the OptiTrack’s highest resolution. 

OptiTrack’s PrimeX 120 and 120W cameras are now available through EST. The new higher-resolution cameras offer the accuracy expected of OptiTrack with higher resolution and increased field of view. These new features enable larger tracking areas for a wider variety of training and simulation scenarios, and larger cinematic virtual production studios.

“OptiTrack has built more than 30,000 3D motion tracking systems in all shapes and sizes. These new cameras open the door to larger venues where we can track more markers that are closer together, and farther away, than we’ve ever tracked before,” said OptiTrack Executive Vice President Stephanie Hines “When your application requires best-in-class precision in a very large volume, nothing compares with the accuracy and durability of the OptiTrack Primeˣ 120 and Slimˣ 120 cameras.”

Each of the three new cameras features OptiTrack’s highest-yet resolution, 12 megapixels. The Primeˣ 120 features a standard 24mm lens while the Primeˣ 120W comes with an 18mm lens with a wider field of view. The Slimˣ 120 is available with a 24mm or 18mm wide lens. 

The Primeˣ and Slimˣ 120 cameras lenses are custom designed with low distortion, “fast glass” for optimal marker tracking and true 10-bit grayscale depth which reduces quantization noise and improves precision, resulting in perfectly crisp images, better centroids and better 3D accuracy. 

The Primeˣ 120 and Primeˣ 120W cameras track active markers, the benchmark for low latency virtual reality tracking, ground truth systems for augmented reality, and high subject count robotics. The Primeˣ cameras easily identify and track passive markers, or retroreflective markers, including spheres, hemispheres, and even flat reflective discs. The Slimˣ 120 is capable of tracking active markers and is a smaller, less obvious option for applications that require the cameras to be more discreet, like a virtual production set or location-based virtual reality.

To ensure the company’s exacting quality standards, the Primeˣ 120, Primeˣ 120W and Slimˣ 120 cameras are designed and manufactured at OptiTrack’s headquarters in Oregon (U.S.). Systems can pair Primeˣ 120, Primeˣ 120W and Slimˣ 120 cameras with any other Primeˣ or Prime Color camera to create the optimal configuration for any use case and deliver the highest 3D tracking accuracy to any environment.

The Primeˣ and Slimˣ 120 cameras work together with OptiTrack’s new Motive 3.1 3D motion capture software featuring Trained Markersets, continuous calibration, skeletal solver and more. Combined, OptiTrack cameras and Motive software enable users to see and analyze tracking data to inform everything from robotics and movement sciences to video game animation, cinematic virtual production and location-based virtual reality.
