Recently I had an opportunity to get my hand on a FLIR Tau 2 640, a 9 Hz refresh rate version with optional 25 mm lens. This is a 10K USD gadget so I am extra careful to handle the test and recheck my gear several time before flight.
Researcher Kimbery Fornace from London School of Hygiene & Tropical Medicine would like to use this camera to survey the population of marque monkey in her study site. This is parts of her study on Malaria, a disease commonly found in tropical country. Malaria causes symptoms that typically include fever and headache, which in severe cases can progress to coma or death. ( Wikipedia ). So you know she is not flying drone for fun but saving life. She is also the only lady who can fly a drone and successfully map a few area here in Sabah.
The camera was mounted on an Alware servo base 2 axis gimbal. Power by a BEC which supply 5.2 v to the micro USB port found at the back of the camera. It output composite video which was connect to a digital video recorder and also a wireless video transmitter to give us real time video and OSD. I am using my tested DJI F 550, control by Naza M V2 and data link. With a 4S 6000 battery, all up weight is 2.7 Kg. It can fly for about 8 minutes.
This is the primary test just to make sure when all system are up and running, they will not interfere each other. I also want to confirm it can handle the extra weight. ( I am 200 gram over the recommended maximum weight ). Although I had the gimbal function enable, but the default gain setting seems too slow. I may want to increase it from 20 to 50 gain and see if thing improve.
I will conduct a few more test before heading to the study site for actual survey mission flight a night.
