Use of Infrared Cameras for Airborne Thermography of Large Areas

Aerial Ther­mo­graphy

By using a helicopter equipped with an image stabilising gimbal, the infrared camera adds another dimension to the world of aerial thermography and the captured image data. An infrared camera in an elevated position provides an excellent thermographic overview for many fields of application. Depending on the task, aircraft as well as drones are also suitable as carriers and offer numerous options.

Fire­fighting from the Air

An infrared camera can also be used to monitor the proper discharge of water containers from the air, as a form of primary forest firefighting. Even in the vicinity of smoke and flames, the distribution of firefighting water can be made visible due to the high thermal resolution of the infrared camera. This in turn allows the response team to quickly evaluate the efficiency of the water tank discharge and where there is still a need for more.

Numerous airborne reconnaissance systems enable InfraTec infrared cameras to provide reliable support for those risking their lives on the ground to fight fires. InfraTec's VarioCAM® HD and ImageIR® camera series are not just infrared cameras, but high-resolution, radiometrically calibrated thermographic systems. They therefore have the ability to measure temperatures even from a great distance. In addition, missing persons can be detected from the air.

Aerial Fire Mapping / Fire Mapping

The number of bushfires and forest fires is increasing worldwide. Fighting them on the ground is made much more difficult by inaccessible terrain and the danger to life posed by the fire. In such cases, aerial fire mapping can provide a remedy. It provides a holistic overview and, with high-resolution thermographic systems, a reliable assessment of the situation. Based on the information gained, firefighting on the ground can be better coordinated and more targeted. Even in smoke, fog or poor visibility conditions, an infrared camera provides the most accurate data.

Airborne fire mapping is the best possible real-time tool for detecting and fighting forest fires. Helicopters are particularly suitable for this purpose, as their flexibility and manoeuvrability allow them to be used even in critical flight situations. In combination with a radiometrically calibrated infrared camera on board, experienced firefighters can quickly and reliably analyse the given situation from the air. Thermography can be used to create a ground temperature map in real time and generate a comprehensive overview of forest fires. The temperature measurements also make it possible to distinguish between burning forest, building structures and mammals or people trying to escape. Measurements on vehicles or industrial structures help to find other sources of dangerous fire.

Agri­cul­tural Research and Preci­sion Farming

Climate change is creating new challenges for modern agriculture. Lack of rain dries out soils and affects groundwater distribution. For a comprehensive soil assessment, an airborne thermography system can provide important data on the moisture content of the subsoil by recording soil temperature. This aerial monitoring helps to apply irrigation in the right places and avoid unnecessary waste of water. Airborne platforms, such as drones, with thermography systems are ideal for analysing soil moisture and other soil conditions comprehensively and from an elevated perspective. With the help of the collected thermographic measurement data, irrigation measures as well as plant growth can be assessed.

Infrared cameras of the VarioCAM® and ImageIR® series also support airborne crop research in the field of precision farming.

Geo Research with Airborne Infrared Cameras

Infrared cameras are able to capture high-resolution infrared images from the air, regardless of visibility conditions, day or night. InfraTec's thermography systems operate in the mid (MWIR) and long wave infrared (LWIR), optional filtering can support spectral detail investigation of soil properties such as composition and thermal conductivity. Mineralogy, mining, basic research and the development of space sensors are geoscience applications that can be carried out by airborne thermography systems. But wildlife research also benefits from the results of aerial thermography, as the increased perspective allows for improved wildlife statistics, for example.

Thermal Mapping with Airborne Camera Plat­forms

Airborne thermal mapping is an essential tool to map the energy budget of individual municipalities on an area-by-area basis. In this way, efforts by municipalities to develop a zero-energy urbanity can be supported by collecting thermographic data quickly and efficiently. The VarioCAM® and ImageIR® infrared camera series provide the robust tools needed to record and collect the necessary thermographic data from aerial platforms such as drones.

Furthermore, distributed heating networks require extended and efficient remote maintenance. With airborne thermography systems, an instant overview of the network's condition can be created. This allows teams on the ground to react immediately to defects and leaks using a thermal map created by the airborne monitoring platform.

Airborne Inspec­tion and Main­ten­ance of Long-distance Power Lines

Electric long-distance power lines form the infrastructure backbone of any country. In order to safely meet the needs of the inhabitants and the local industry, trouble-free as well as uninterrupted availability is a must for power suppliers. To ensure this, infrared cameras are used, which are mounted on helicopters for inspection purposes. A proven inspection method for years.

The main task of the thermography system is to detect "hot spots" along the power line and on insulators. This detail is a proven indicator of material defects that can lead to system damage or failure. Thermography is also a reliable method for remote non-contact detection of hot spots in underground electrical cables, which also works perfectly from airborne platforms from an elevated position. Alternative visual inspections near the ground do not offer the speed and efficiency of an airborne thermographic inspection. When using video cameras or binoculars, the probability of detection is much lower and the movement from the air is much slower.

Separate Filter & Aper­ture Wheel – Spec­tral Ther­mo­graphy

The combination of a separate filter and aperture wheel, allowing a total of 35 freely selectable combinations, is prerequisite for a universal application in measurement tasks with high object temperatures and in the field of spectral thermography. The neutral density filters used for signal attenuation or the combination of spectral filters and apertures reliably prevent interference effects.

Multispectral Feature

The multispectral feature makes it possible to record sequences with constantly changing spectral filters. Images are recorded synchronously with a rapidly rotating filter wheel equipped with the filters. It may be possible to switch between up to seven filters, depending on the version. Due to this the multispectral measurement can be optimised to suit the measuring task if the preset ranges are unsuitable. The integration times can be adapted within the limits calibrated for this filter.

InfraTec thermography - Geometrical Resolution

Geomet­rical Resol­u­tion – Effi­cient Analysis of Complex Assem­blies

InfraTec's infrared cameras with cooled and uncooled detectors have native resolutions up to (1,920 × 1,536) IR pixels. Spatially high-resolution thermograms ensure that components and assemblies are imaged down to the smallest detail and thus defects can be reliably detected and precisely localised.

InfraTec thermography - Thermal resolution

Thermal Resol­u­tion – Determ­in­a­tion of Differ­ences of Only a Few Millikelvin

For detection of small temperature changes InfraTec's infrared cameras offer thermal resolutions up to < 15 mK in real-time operation. By using the Lock-in Thermography method it is possible to further increase this resolution significantly. For this purpose test objects are periodically excited and non-destructively examined for defects and irregularities.

Integ­rated Trigger / Process Inter­face and Inter­faces – Digit­ally Controlling of a Infrared Camera and External Devices

The internal trigger interface guarantees highly precise, repeatable triggering. Each of the two configurable digital inputs and outputs are used to control the camera or to generate digital control signals for external devices. In this way, for example, the operation of a printed circuit board and the interval of a measurement can be synchronised.

The selection of different camera interfaces allows the processing of analog data, such as the voltage directly through the camera and thus the insertion of this information into the thermal image data. Relevant variables can be included in the evaluations with the software, which makes it easier to draw conclusions about the causes of temperature changes.

Gimbal Systems for Heli­copter Mounting

InfraTec offers various infrared camera systems for fixed mount use in airplanes as well as for integration into precision gimbals. Thereby, the infrared camera can be exactly positioned within a µrad range to track automatically. A handy remote control allows for camera operation directly via the control of the gimbal.

Gimbals, or gyro-stabilized platforms, have been used for many years as very effective systems for airborne thermography in the inspection of high-voltage power lines, pipelines and industrial plants, as well as in the search for energy and material pollution.

Gimbal for helicopter mount

Due to their high-precision stabilization, images of distant objects can be accurately captured despite movement of the airborne vessel carrying the gimbal. Integrated into the gimbal are cameras for both, the visible (visual camera) and in the infrared radiation spectrum (infrared camera), a laser rangefinder and laser target designators.
