Hello,
I have a FLIR VUE PRO R 640 Thermal Camera fixed mounted on my custom Drone. For the last couple of months, this sensor is not capturing the quality data and the use of FLIR TOOLS with different trial changes in the parameter becomes necessary which takes a lot of time and effort to identify the hotspot and other Solar Inspection related parameters.
My setup includes -
a) FLIR Vue Pro R 640 Camera with HDMI Converter
b) FLIR Original cable
c) 5V 2A Powerbank
FLIR Settings -
a) Ironbow
b) ROI - 75
c) DDE - 10
d) ACE - 4
e) SSO - 15
Radiometry Settings -
a) Sky - Clear
b) Humidity - Medium
c) Air Temperature - 40°C
d) Emissivity - 94%
e) Subject Distance - 25meter
Additionally, this camera also stops capturing the image in the mission itself at any time. It can work for the whole day flawlessly or it can also stop the image capturing after 2 minutes of triggering, every time I try troubleshooting.
Another issue that I came across recently, the above-shared discontinuation of image capturing got cured with the change in SD card.
I am quite interested in solving all the above issues on priority. If anyone has come across any of the issues and can help me out solving this, Please update me with the solution. Should you have any queries, feel free add up in the comment/discussion.
Recently I have started getting noisy images with stripes. Please check the same in the attached images.
Please find the sample (handheld) images in the attachment.
Thank you for your support.
What caught my eye was "Air Temperature: -40 °C":
this camera is specified down to operating temperatures of -20 °C, but not below.
If you have been operating it below that, it may have suffered permanent damage. (E.g. broken or intermittent solder joints od similar issues.) Other sources for permanent damage (crash landings? excessive vibrations? ...) may apply as well.
If you can have the camera checked/diagnosed by FLIR, I'd suggest to do so.
The noisy images with stripes could be a power issue. I've had this happen on analog FPV cameras for race drones in the past. Since the operating voltage is 5 VDC – 28 VDC, perhaps your power bank is outputting slightly less than 5V? I'd try another power bank or a 10V UBEC.
Also, do you have access to FLIR support? They'd have the most experience with these cameras. Do you plan on putting it on gimbal? I am also worried that vibrations might cause bad output from sensor.
Thank you, Rolando Gonzalez
I have doubts about the same that power source must be creating this issue. I am in line for testing different power banks of 5V output. Maybe it is happening due to the power bank use cycles crossed a limit.
I have a plan to put it on a gimbal but all the FLIR camera gimbals are quite costly whereas my need is quite a basic one. I do not need something to power my camera up. But such gimbals for this kind of FLIR camera is not available as of now. So, I am working on a hard 3D print mount. That works for me.
I do have access to FLIR support but they can hardly provide any support online apart from Rebooting suggestions and some basic technical query help. Mostly they ask to send it for repair and that is not available in India.
Thanks for your time and response.
You say you do not need power source for the camera? Perhaps the issue with stopping recording might be power issue as well. Instead of other 5V power banks, why not use 2S or 3S Lipo where voltages are way higher than the minimum (5V) required by camera?
