Simple kite aerial thermography (KAT) with a Flir One (video stills)

edited July 9 in General
Drone pilots use thermal imagers professionally for measuring heat loss from buildings and heat generated by electrical faults.

Here is some KAT from last summer using a Flir One on the lockable section selfie stick shown below. The thermal imager is normally secured to the phone with PVC tape and the phone encased in a standard heavy duty case:

For vertical work, with the phone horizontal, we use the simple selfie stick, as with the brickworks shots at the foot of:
http://armadale.org.uk/brickworks.htm These shots were taken at night in darkness.

In archaeological work, you hope to achieve differential contrast to delineate archaeological residues in the ground. This can be by thermal inertia (storage heater effect) or by the differential transpiration (like sweating) of crops above different features. We have found that the best contrast comes after a shower of rain when some regions are dry and others still damp or wet.

Whereas our old Flir PathFindIRs really needed a gimbal (which we did not have), for some reason, the Flir One (or at least this generation) works fine.

The thermal images below were captured during the daytime. Note the visble spectrum outline produced by the second sensor in the imager.
