Advanced Onboard Video & Image Processing for Unmanned Systems

Sightline Applications
Sightline-Applications

UAV Camera Video ProcessorSightline Applications develops onboard video processing solutions for unmanned systems in the civil, commercial and military sectors.  Our high-performance embedded systems are ideal for integration into unmanned vehicles serving a wide variety of end uses, including Intelligence, Surveillance & Reconnaissance (ISR), environmental surveying, infrastructure inspection, and agricultural mapping.

Onboard video processing brings a wide range of benefits to unmanned vehicles, such as low latency feedback for gimbal control and landing guidance, a full digital video path, and low requirements for Size, Weight and Power (SWaP).

Video Processing Software

Our Video Processing Software provides a powerful foundation for all of our processor systems, and includes a constantly expanding suite of functions that improve the performance of unmanned video platforms. Below is an overview of the capabilities available.

HD Video

Provides a range of HD video capabilities, including 1080p/30 and 720p/30 processing and encoding.

Video Stabilization

Dramatically improves video by removing high-frequency noise and frame-to-frame jitter. Also provides ability to correct camera frame-to-frame rotation in applications with platform roll motion, such as unmanned aircraft.

Electronic Stabilization

Roll Correction

Scene and Object Tracking

Scene tracking provides powerful gimbal feedback based on the entire scene. Tracked objects can be isolated from background using advanced image analysis and motion estimation, and persistent tracking is possible even when view of tracked object is temporarily blocked.

Telemetry Data

Provides low latency location data from object tracking, scene steering, and MTI objects, as well as temperature data from radiometric cameras and focus telemetry for autofocus implementations.

Video Encoding and KLV Metadata

Available Ethernet video encoding outputs for reducing system bandwidth include MPEG2 TS, MPEG4 and RTP M-JPEG. KLV metadata is generated in accordance with MISB standards 0102.10, 0601.7, 0603.2, 0604.3, and 0903.3.

Landing Aid

Provides position, range, and angle data to landing systems of aerial vehicles, and automatically finds and tracks a landing pattern. Works independently of GPS, enabling accurate landing in GPS-denied environments.

Detection Algorithms

Provide important situational awareness information and aid in tracker initialization. Real time onboard MTI (moving target indication) modes include:

  • Identification of multiple (5) trackable moving objects
  • Identification of multiple (100) very small moving targets from an aerial camera
  • Moving object detection from fixed, low angle camera systems
  • Histogram difference detection mode identifies unique colours within a scene.

Video/Snapshot Recording

H.264 video, full resolution JPEG snapshots with EXIF data, full pixel depth PNG snapshots with metadata, and telemetry data can all be recorded and saved to a local SD card or remote FTP.

Video Enhancement and Overlays

Enhancement options to optimize video for particular applications include Digital Zoom, Contrast Limited Adaptive Histogram Equalization (CLAHE), Local Area Processing (LAP), de-noising and edge sharpening, false colour schemes, and extended 14 bit-depth processing.

Multi Camera Video Presentation

Highly versatile options for optimized presentation, transmission and display of multiple video streams. Includes Picture in Picture (with customizable PiP location), split screen, quad screen, and blending of multi-spectral inputs into a single image.

Focus Telemetry

Full autofocus functionality for a range of EO block cameras and lens assemblies, available independent of tracking telemetry.
