Detection Range & Field of View

  • The NEFELI pipeline is able to process two video streams concurrently.

  • The stream captured by the front viewing camera undergoes continuous processing at 14Hz.

  • The remaining seven camera feeds are systematically processed in series, with each camera updating at a frequency of 1Hz.

  • NEFELI ensures that every angle is accounted for, creating a complete 360-degree field of view.

Characteristics

A pivotal attribute of NEFELI software is its hardware-agnostic design, ensuring compatibility with a range of computing units adhering to specific requirements and equipped to accommodate video streams from any 4K camera. Additionally, NEFELI's software is optimized for GPUs, facilitating faster development and garnering broader support from a larger developer community. Its modular algorithmic architecture enables timely integration of the latest advanced machine learning algorithms, ensuring the system stays updated with the latest technological strides.
