The data handling of many sensors that scan a single target, called multi-sensor networking, is an important capability to support large object applications. Many sensors are required when the target object is larger than what a single sensor is able to scan, or when multiple views are required to capture key features of an object.
In this article, we will present four main challenges that arise in multi-sensor networks: (1) sensor wiring, (2) sensor discovery, assignment, and mapping, (3) sensor alignment to a common coordinate system, (4) sparse or dense network processing.
