Military Vetronics Systems
Gigabit Ethernet (GigE) is a natural choice for video transmission within military ground vehicles, due to its light-weight, off-the-shelf cabling, networking capabilities, and ability to support a range of different computing platforms.
Pleora’s external frame grabbers are typically used in vehicles where cameras with analog or Camera Link interfaces already exist. While GigE Vision® cameras are useful in these vehicles, they may not be practical due to a desire to maintain existing cameras, sensors, and optics. In these cases, external frame grabbers simplify system implementation and maintenance, extend the life of legacy systems, future-proof designs, and enhance performance.
In the diagram below, existing analog and Camera Link cameras are converted to GigE by Pleora’s iPORT™ Analog-Pro External Frame Grabbers and iPORT CL-GigE External Frame Grabbers. This allows software developers to receive video from and control analog, Camera Link, and native GigE Vision cameras using a single physical interface and a single SDK. At the PC, all the interfaces connect via GigE, eliminating the need for a computing platform with an available peripheral card slot. As a result, system designers can reduce system size, cost, and power consumption by using computing platforms with smaller form factors, such as laptops, embedded PCs, and single board computers.
The low, consistent “glass-to-glass” latency in which Pleora’s external frame grabbers and eBUS™ SDK deliver video make them ideal for use in Local Situational Awareness (LSA) systems, as well as Closed Hatch Driving (CHD) applications, where the vehicle’s windshield is replaced by cameras and video monitors.
Pleora’s external frame grabbers can be set to multicast image data to multiple computing platforms simultaneously, including vDisplay HDI-Pro External Frame Grabbers, using an off-the-shelf GigE switch. This allows vehicle occupants to decide “on the fly” which video streams they need to see, without any changes to cabling or software configuration. The video is also transmitted to an onboard Transcoder Gateway, where it can be compressed for storage and wireless transmission to a command center, other vehicles, or battlefield troops who can view the video on tablets or smartphones.
Beyond LSA systems, Pleora's GigE Vision-compliant video interfaces are ideal for vision systems used for sighting, threat detection, weapons targeting, and surveillance in ground-based vehicles, navel vessels, manned and unmanned airframes, and standalone system for persistent surveillance.
