Workswell WIRIS – thermal imaging camera for drones

Advanced thermal system for UAV

Workswell WIRIS thermal imaging system for unmanned aircraft is a compact system that combines thermal camera, a digital camera and a control unit in one case.

Workswell WIRIS is not just another device that can be attached to your drone. Workswell WIRIS is equipment which provides your drone with endless new uses and for many companies is the exact reason why they should acquire a drone! We offer our clients complete sets, including ready to fly drones.

Workswell WIRIS 2nd gen

Since the end of 2016, the second generation of Workswell labelled “WIRIS 2nd gen” has been available. Apart from its temperature range extended up to 1500°C (using a high temperature filter), the second generation of the Workswell WIRIS product offers the following functions:

  • SBus
  • CAN bus
  • A faster 10Hz GPS with a jack connector
  • The new TIFF format for storage of images
  • A possibility of controlling the equipment through TCP/IP
  • Real time hours are significantly more accurate now
  • Digital outputs for the autopilot and GPS synchronisation
  • An integrated stabilised source for the RC receiver
  • 4 openings for an easier installation on the gimbal

For this reason, there are currently only 7 digital PWM inputs available (the eight being used for the SBus).

Control with your standard RC controller

Workswell WIRIS is a revolutionary thermal imaging system primarily due to its possibility of full control in real time during the flight via a standard RC controller.

Remote control with WIRIS screen

Fully radiometrics and temperature measurement

Remotely, it is possible to view and store fully radiometric and calibrated image data (images and video) – ie. records that retain all the information about the capturing parameters, which can be subsequently fully processed in the supplied software.

WIRIS temperature measurement

Digital ZOOM

If the task is to measure distant objects, then you will appreciate the digital zoom option. In the case of a digital camera, a zoom of up to 16x is available; in the case of a thermal camera then up to 14x (with the resolution 640×512).

Photogrammetry and 3D models

Images captured by the system are fully radiometric and contain information about GPS coordinates in the EXIF metadata of the files. Such images can be subsequently used to create a 3D model – with the aid of a specialized software (for instance Pix4D).

Advanced software

It is possible to work with the produced images on a PC. It is possible to modify all parameters and change accessible setting. It is possible to insert into the image, further measuring functions (temperature in the point, minimum and maximum in any area, thermal profile, etc.) and many other functions and features.

GPS

You can link the image temperature data with the value from an external GPS receiver. GPS data is saved into the EXIF part of the JPEG file and is available for use.

HDMI Wireless transfer

The video output for the WIRIS system is standard HDMI. When using for instance Connex the wireless transfer of an image up to the distance of 1 km is possible! On the standard screen on the control unit you can view the video output as well as all menus and the other system functions.

Calibration

Each Workswell WIRIS thermal imaging system is shipped fully calibrated and comes with a calibration certificate. The measurement precision of each WIRIS system is tested using reference black body sources over the whole range of measured temperatures.

Modes and alarms

Standard Infrared image

Standard mode allows users to set different color palettes, maximum and minimum temperature analysis, set automatic or manual temperature range and displays all the data on the operator’s controller on the ground.

Alarm (security) mode

Alarm mode allows users to set a temperature limit and see (find) only objects (places) with higher or lower temperature than is set, eventually temperatures between or above and below two limit values. This is the key mode for security and industrial applications. Maximum and minimum analysis is also available in this mode.

Digital camera mode

Digital camera mode allows the operator to see the area in the visible spectrum. Parallel view of digital camera enables better orientation in space and user can easy guide the drone above the desired location.

Use our system in many ways

Our customers use Workswell WIRIS in many different ways for dozens of applications. This extensive gallery of photos and thermograms might help you to imagine how the system could be useful for you. Please don’t hesitate ask to your application!
