Drones Tap a Variety of Video Solutions

Eyes in the Skies

In one way or another, much of today’s commercial drone development revolves around video. Technology options range from single-chip solutions to complex networked arrays.

By Jeff Child, Editor-in-Chief

Commercial drones represent one of the most dynamic, fast-growing segments of embedded systems design today. And while all aspects of commercial drone technology are advancing, video is front and center. Because video is the main mission of the majority of commercial drones, video technology has become a center of gravity in today’s drone design decisions. But video covers a wide set of topics including single-chip video processing, 4k HD video capture, image stabilization, complex board-level video processing, drone-mounted cameras, hybrid IR/video camera and mesh-networks for integrated multiple drone camera streams.

Technology suppliers serving all of those areas are under pressure to deliver products to integrate into video processing, camera and communications electronics inside today’s commercial drones. Drone designers have to pack in an ambitious amount of functionality onto their platforms while keeping size, weight and power (SWaP) as low as possible. Feeding these needs, vendors at the chip, board and system-level continue to evolve their existing drone video technologies while also creating new innovative solutions.

Video Processing SOC

Exemplifying the cutting edge in single-chip video processing for drones, Ambarella in March introduced its CV2 camera SoC (Photo 1). It combines advanced computer vision, image processing, 4Kp60 video encoding and stereovision in a single chip. Targeting drone and related applications, the company says it delivers up to 20 times the deep neural network performance of Ambarella’s first generation CV1 chip. Fabricated in advanced 10nm process technology, CV2 offers extremely low power consumption.

The CV2 camera SoC combines advanced computer vision, image processing, 4Kp60 video encoding and stereovision in a single chip.

The CV2’s CVflow architecture provides computer vision processing up to 4K or 8-Megapixel resolution, to enable object recognition and perception over long distances and with high accuracy. Its stereovision processing provides the ability to detect generic objects without training. Advanced image processing with HDR (High Dynamic Range) processing delivers outstanding imaging even in low light and from high contrast scenes. Its highly efficient 4Kp60 AVC and HEVC video encoding supports the addition of video recording to drone platforms.

At the heart of the CV2 is a Quad-core 1.2 GHz ARM Cortex A53 with NEON DSP extensions and FPU. CV2 includes a full suite of advanced security features to prevent hacking, including secure boot, TrustZone and I/O virtualization. A complete set of tools is provided to help embedded systems developers easily port their own neural networks onto the CV2 SoC. This includes compiler, debugger and support for industry standard training tools including Caffe and TensorFlow, with extensive guidelines for CNN (Convolutional Neural Network) performance optimizations.

Board-Level Solutions

Moving up to the board-level, Sightline Applications specializes in onboard video processing for advanced camera systems. Its processor boards are designed to be integrated at the camera level to provide low-latency video processing on a variety of platforms including commercial drones. Sightline offers two low SWaP board products. Both products are supported by SLA’s Video Processing Software: a suite of video functions that are key in a wide variety of ISR applications. The processing software has two pricing tiers, SLE and SLA. SLE provides processing only and SLA processes the video and provides telemetry feedback. . …

Transform IoT Audio, Voice, and Video Interactions

NXP Semiconductors (now part of Qualcomm) recently introduced the new i.MX 8M family of applications processors specifically designed to meet increasing audio and video system requirements for smart home and smart mobility applications such as over-the-top (OTT) set-top boxes, digital media adapters, surround sound, sound bars, A/V receivers, voice control, voice assistance, digital signage, and general-purpose human machine interface (HMI) solutions.NXP-iMX8M-FS

The concept of the smart home is expanding rapidly, heightening consumers’ expectations for audio and video entertainment and transforming the requirements for consumer electronics devices. NXP’s i.MX 8M family addresses the major inflection points currently underway in streaming media: voice recognition and networked speakers in audio, and the move to 4K High Dynamic Range (HDR) and the growth of smaller, more compact form factors in video.

NXP’s i.MX 8M family of processors has up to four 1.5-GHz ARM Cortex-A53 and Cortex-M4 cores, flexible memory options and high-speed connectivity interfaces. The processors also feature full 4K UltraHD resolution and HDR (Dolby Vision, HDR10 and HLG) video quality, the highest levels of pro audio fidelity, up to 20 audio channels and DSD512 audio. The i.MX 8M family is tailored to streaming video devices, streaming audio devices and voice control applications.

Capable of driving dual displays, the new devices include:

  • The i.MX 8M Dual/i.MX 8M Quad, which integrates two or four ARM Cortex-A53 cores, one Cortex- M4F core, a GC7000Lite GPU and 4kp60, h.265 and VP9 video capability.
  • The i.MX 8M QuadLite, which integrates four ARM Cortex-A53 cores, one Cortex- M4F core and a GC7000Lite GPU.
  • The i.MX 8M Solo, which integrates one ARM Cortex-A53 core, one Cortex-M4F core and a GC7000nanoULTRA GPU.

The i.MX 8 applications processor is highly scalable with a pin- and power-compatible package and comprehensive software support. The i.MX 8 multi-sensory enablement kit (MEK) is now available to prototype i.MX 8M systems. Limited sampling of i.MX 8M will begin in the second quarter of 2017, and general availability is expected in the fourth quarter of 2017.

Boldport Club: Behind the Scenes

We first met London-based engineer Saar Drimer in December 2015. At that time, his was running Boldport—a hardware and prototyping consultancy that specializes in circuit boards—from a workspace was in one of the characteristic arches underneath London Bridge Station. A lot has changed since then. Today, Drimer has a new workspace and he is running Boldport Club, which is a monthly electronics hardware subscription service. We recently met up with him to discuss his work and newest endeavors.

“The big change is the club I started early this year,” Drimer explained. “I posted my initial ideas online and the response was very promising, around 170 members signed up in the first month.”

N. Mittal’s Dorm Room-Based Workspace in Bombay

The workspaces we see in Circuit Cellar are fascinating. The engineers who open up their rooms, garages, and cellar’s normally have a lot of equipment and sufficient access to components and facilities. But what about an Indian university student’s workspace? Wisse Hettinga recently visited with Nishant Mittal, a student at the Indian Institute of Technology (IIT Bombay). Mittal discussed his small workspace space in his dorm room, as well as his plans for the future.
