Project Overview

A large-scale infrastructure deployment required a real-time panoramic video system capable of stitching multiple camera feeds into a single 4K wide-angle stream while enabling cross-camera object tracking. Built on the Qualcomm QCS8250 platform, the solution needed to deliver low-latency processing, AI inference, and stable performance within strict power and thermal limits for fanless edge deployment. Below are key requirements:

Multi-Camera Fusion System

6 synchronized cameras stitched into real-time panoramic video output feed

Low-Latency Processing

Deterministic pipeline delivering sub-50 ms end-to-end system latency total

Edge AI Tracking
