Flir E4 Thermal imaging camera teardown

LOL that might be the one I sent back....

Why did you send it back ?

[gemrough]

Ordered another one from zoro @ 30% off.

Yeah after reading the thread and seeing the zoro coupon codes i thought about the same thing.

So this was in the hands of FLIR and they did nothing!!! They 100% sold me a E4 with better specs than they claim.

I can just imagine the referb/service tech's inner monolog:

F#ck it - they are just gonna hack it anyway... <rubber stamp sound> NEXT!

[clubmkred1]

But the reflective temperature always displays 20 degrees F, the relative humidity is always 50% and the atmospheric temp is always 68 degrees F no matter what.

No such problem here. But you may want to wait for the next patch.

So it seems as if, at least, another user has the same problem. Is there anyway to fix it so it works correctly? Do I need to undo the hack, and start over? Any ideas? Who would the next patch come from? This forum or FLIR?

[Bud]

You do not want patches from Flir.

Hello Guys I need help from you... I have realy interesting case... I bought Flir E4 camera in february 2015 (so recently). This camera has 2.3.0 frimeware. My resolution is 80x60 and I'm sure about it

In /FlashFS/system/appcore.d/config.d/conf.cfc is 6608 bytes.

When I do the hack resolution I have error in "apply.py line 89" - please see screen from CMD. Is this mean that I bought hacked camera? If FileZilla I see that common_dll.dll file has different date that other files... What do you think about this? Is it any hope for me?

All settings stuff is in
.image.sysimg.basicImgData.objectParams
ambTemp        293.14999 (20 C)
atmTemp         293.14999 (20 C)
emissivity            0.94999999 (e0.95)
objectDistance     2  (2m)
relHum                0.5 (50%)
(other settings there is for external lens)
If I change them from my "2.3.0 menu 2014" they will be saved and seen in image info too
and on report pdf too. Ext optics settings are moving too from menu.

But the same info is there and this is not affected:
.image.sysimgInstances.ref.basicImgData.objectParams
.registry.image.sysimgInstances.main.basicImgData.objectParams

Mine gave me that exact error but it was actually modified and I confirmed it with the the pictures stored on the camera.

post a screen shot of your stored image stats.

Created an account so I could thank all involved in building/sharing the solution for the E4. 

I ordered from Amazon and received just yesterday.  Imagine my surprise to find 1.22 firmware.  Had a calibration date of April 2014.

I upgraded menu and resolution yesterday evening with not much trouble.

Thanks again.

Hello guys,

I would like to ask you for help. I know mainly FLIR users are here , but many of you do have other thermal cameras .
I am looking for any non Flir thermal images. Photos from Fluke, Testo and other cameras.

Why? I did update BFIC to load SNP, BMT, IRI, ISI, IS2 file formats. And I need more photos for testing purposes.
So I am looking for testers and owners of other TIC, who are interested in new software development.
One software for all Thermal Cameras.

Hi all,

First, I wanted to say thanks for the amazing work that's been done here to open up all of the E4's capabilities.  It's truly impressive!

My E4 arrived yesterday and after the obligatory initial thermal survey of the entire house, I immediately set about the upgrade process outlined by gemrough here https://www.eevblog.com/forum/testgear/flir-e4-thermal-imaging-camera-teardown/msg585647/#msg585647.

I'm having trouble connecting to the camera over RNDIS -- the new adapter always comes up with the automatic address 169.254.202.x.  I've tried pinging 169.254.202.2, as well as configuring a static IP of 192.168.0.1, gw 192.168.0.2, but no luck there.  To prevent conflicts with my LAN, I disabled that adapter during this procedure.

The instructions above suggested using Set_RNDIS_permanent.fif, but I'm a bit apprehensive about that.  If I set permanent RNDIS and am still unable to access the camera over IP, am I permanently stuck in RNDIS mode?  Does doing a factory reset via the E4's menus recover from applying that FIF, or is it a one-way trip until I apply a corrective FIF (which I'd be unable to do without successful IP connectivity to the camera)?

Thanks!

I like playing around with with BFIC but the output always shows more JPG aliasing to me compared to the stand alone flir.php. It's almost like BFIC is recompressing it more. Also can you look into adding an option to output as PNG in the future?

[OrBy]

Is anyone interested in panorama images?

Hey tomas123 - have you played around with ICE 2.0.3 yet? Some interesting new features but it looks like it dithers out almost all the data when you feed it the grey tiff's now. 1.4.4 still works like a charm at least still.

[Bud]

To prevent conflicts with my LAN, I disabled that adapter during this procedure.

I am on W7 and I have a router with 192.168.0.1 address. Disabling the LAN adapter did not work for me. But simply unplugging the PC LAN cable from the router worked and the camera boot to 192.168.0.1/2 address.

unable to access the camera over IP, am I permanently stuck in RNDIS mode?

yes

[tomas123]

Hey tomas123 - have you played around with ICE 2.0.3 yet? Some interesting new features but it looks like it dithers out almost all the data when you feed it the grey tiff's now.

I stitched dozen of images with the new ICE version and it works like a charm (correction of distortion etc)
no dither, see my sample

save the 1644x974 (!) image and view details with an image viewer


I use this quick-and-dirty windows scripts to expand the gray level for better stitching
save panorama as 16 bit stitch.tiff and re-compress the level of stitch.tiff with
       > convert stitch.tiff +level x,y panoraw.png

Yup that did it.
Few little tweaks for my setup but it works!

Thanks again tomas123!

[ixfd64]

It seems FLIR has reduced the price of the E8 to $3,995 again. I wouldn't be surprised if the 2.3.0 hack has something to do with it.

WOW That is a fantastic IR image!!!   It is amazing what you can do with the extra tools.  By the it looks like one of your street lights is not working... LOL

Purchase an E40BX on eBay two weeks age but the seller forgot the battery Argh...   After testing will do the E60 update.

 

[DaveWB]

By the it looks like one of your street lights is not working... LOL

I thought he just did a bad job stitching then I realized it would have been hot if it was working lol, I'm still amazed at it. I couldn't find any errors in the stitching

[tomas123]

background information:

I used a simple monopod to avoid horizontal movements and strong camera rotations (vertical lines)
18 images taken in 3-4 minutes

shut on the camera >10 minutes before using to prevent strong temperature drift while taking the image sequence (shutter ->  flat-field correction)

the image order is arbitrary but use a generous overlapping

see the original images of this sequence (resized to 160x120 pixel)

Code: [Select]

montage IR_*.jpg -geometry 160x+2+2 montage.jpg

Hint: with the large overlapping you can delete a single image, if ICE has trouble in a specific range

compare the results

Hi all, new to the forums. Been reading this thread for the last week or so. Lots of really great work done here. Tomas123, awesome images!

Why non Flir, if you have still trouble with Flir 

Here you find a nice Flir image from a Flir T640, where BFIC shows wrong colors in real image
