Lightweight IR camera for use on drones

LightWeight radiometric thermal imaging camera

Radiometric video recordings for maintenance can be received from a new lightweight camera for airborne use with GPS capability and GoPro interface.

Recorded by drones, UAVs and other flying objects, infrared images and videos from the air are becoming increasingly important in industrial maintenance. In some cases, the cost savings compared to existing applications are enormous. The relaunched optris PI LightWeight, a kit consisting of a weight-reduced infrared camera and an equally light mini PC now ensures even better flight thermography. When asked about the enhancement, Torsten Czech, engineer and Product Marketing Manager at Optris, declared that “customer requirements and the latest technological developments have helped shape the second PI LightWeight generation”.

The optris PI LightWeight is still the only system on the market which produces fully radiometric video recordings. The recordings can be started and stopped via remote control and subsequently edited. The system has a special interface for visual GoPro cameras. USB GPS modules are also supported and the geographical coordinates saved in each single image. The infrared camera and the mini PC have a total weight of only 380 grams.

The new PI LightWeight can be fitted with the optris PI 450 (382 x 288 px) camera model or the optris PI 640 (640 x 480 px) VGA camera. Video recordings of up to 80 Hz in QVGA resolution and up to 125 Hz in VGA sub-frame mode (640 x 120 px) are possible. The unlicensed PI Connect analysis software can be used to extract and analyse sharp single images from the video data. The cameras are powered via USB from the mini PC and have a spectral range of 7.5 to 13 μm. In addition, four different optics can be selected for each model, depending on requirements.
