Fulcrum Air - thermal mapping



FulcrumAir has multiple sensors ready to go and mounted on one of our E2500 drones. A FLIR thermal camera paired with a 20MP RGB camera is used for thermal/RGB inspection and mapping. A GeoCue TrueView 410, with Quanergy M8 and 2x 20MP RGB cameras is used for the LiDAR mapping operations. We can mount many different sensors to our E2500 drone as we can manufacture a custom mount and seamlessly integrate the electronics and software.

Thermal & RGB camera combo

FLIR Vue Pro R is a high quality radiometric thermal camera. This is paired with a 24MP RGB camera that can be used to take high quality still images or record video. They are housed together and both images can be accurately geotagged.

GeoCue TrueView 410 LiDAR

The LiDAR unit that has been selected for use by FulcrumAir in 2020 is the GeoCue TrueView 410. The 410 is mounted onto the E2500 RPAS and can reach a flight times of 24 minutes at a 3500ft density altitude. Point density can reach ~450pts/m2 with 3 overlapping passes, ~300pts/m2 with 2 overlapping passes and ~150pts/m2 with a single pass. With our mobile van/base station, FulcrumAir can fly up to 650 acres of survey grade LiDAR per day (1 square mile, 2.6 square km).
