Line Scan Camera

The Rotortuner Line Scan Camera is an advanced blade tracking sensor for the in-flight measurement of rotor blade height and lead/lag. 

Description

The Rotortuner Line Scan Camera is compatible with the RT-6, RT-2000 and RT-5JS+ products.

The Rotortuner Line Scan camera is an advanced optical blade tracking sensor. Utilising the latest advances in CCD and processing technology the Linescan camera provides many benefits to the operator. With the 10-bit image processing and the proprietary “find edge” filter the camera is able to intelligently determine the position of each blade tip. This allows the operator to make corrections based on consistent data. Measuring at the tip also means there is no requirement to mount the camera underneath the path of the rotor blades. This provides the operator with the flexibility to operate the camera either externally or internally.

Benefits

  • An intelligent blade recognition algorithm provides consistent data.
  • Tracks at the blade tip provide optimum information on each blade.
  • 10-bit image processing, providing reliable operation over a wide range of environmental conditions.

This version incorporates a total redesign of the camera ergonomics. This has produced a camera that is both lighter and easier for the operator to use. The rear face has been angled to make viewing of the tracking LEDs easier and line of sight target tags have been added to aid with the rotor tip line up.

The camera electronics utilise the latest in CCD and processing technology. This has provided the following benefits:

  • more responsive in low light and "blue sky" conditions
  • 10-bit processing with latest DSP
  • data acquired as 1024 level greyscale image
  • 22-degree window hardware capability, firmware currently supports 7 degrees

The new software design now provides an easy upgrade path.

  • Extra hole added
  • Positioned for perfect weight distribution
  • Ability added to attach the handle and monopod at the same time

Algorithm improvements

  • Greyscale processing for improved low light performance
  • Background subtraction for clearer blade images
  • Smoothing and edge detection algorithms for blade tip enhancements
