Sony is launching its first camera tracking system, OCELLUS (ASR-CT1), specifically designed to simplify and facilitate augmented reality and virtual production applications in broadcast and cinema by providing marker-free camera tracking through multiple sensors. Exhibited at the NAB Show 2025 in Las Vegas, OCELLUS is camera agnostic and can be used with both cinema and broadcast cameras. OCELLUS, perfectly suited for virtual production such as In-Camera VFX and AR, sends the camera position and orientation data while the camera is shooting. The system comprises a sensor unit, a processing box, and three lens encoders, and can be used with Sony Cinema Line cameras, system cameras, and non-Sony cameras. With the five image sensors and Sony's Visual SLAM (Simultaneous Localization and Mapping) technology, the system creates a reference map, enabling stable marker-free tracking both indoors and outdoors. All three components of the OCELLUS camera tracking system are designed to be durable and resistant to dust and moisture. Both the Sensor Unit and Processing Box feature cooling fans to prevent overheating and ensure reliable performance.
