Hello again : )
And thanks again for your amazing job Joe-c!

I use the Seek Thermal Compact Pro for Android. I I've done some measurements using the Box ROI (range of interest) tool and I noticed some problem:
Changes in the frame out of the Measurement Box affects significently on the measurment inside the Box. It looks like a wrong calculation of the algorithm, that considers also pixels out of the measurment box to calculate the temp?
Does someone know about it? maybe i did something wrong?

I add few photos to illustrate it -
1. I measured a 50c plate with the measurment box, and when inserting my hand to the frame temp changed in ~5c.
2. There are 2 measurments in different distances: 30cm and 40cm from the plate, you can see a change inthe calculated temp between them (although nothing was changed) that is also due to the fact that in the 30cm distance the plate catch more pixels out of the measurement box.

Thanks in advance,
Tal

Hi Tal,
thank you for show the problem.

I tried to found a problem with the Box measurement but it work like expected. But after change from Thermal Expert to Seek thermal XR i found the problem.

Its not the Measurement, its the image aquisition from the Seek.
You can see this a better way:
1. set a measurement Point (middle mouse klick)
2. by default the 3x3Kernel is active.
(that means the center pixel and all neighbours are merged to the result value)
3. doubble click on the Spot and go to the "Meas Grid"
4. disable the "Kernel 3x3"
5. enable the "Show Raw"

Now you have a single spot (pixel) Value and see the Raw Ushort Value and the calculated temperature.
By moving somwere outside of the area with the Spot, you will see the Raw value is shifting relative to the rest of the image.

i need to look where the problem is...

Thank you for your response Joe-c,
For my application i must use the measurement box, so would be happy to hear news about that.
By the way, do you have a good experience with the Thermal Expert or other camera? Important to me is a relible and stable temp measurement, +-1c accuracy.

Thanks,
Tal

Hello,

is it possible to get the standard deviation of the marked field?

the Problem will be fixed on next version. But for now you can use the TCamDll, that support the Seek Pro without the shift.

I like the TEQ1, but i did not enought measurements to recommend the Camera for your case. but i beleave it will be good enough.

not yet. maybe later.

Joe-c, how difficult would it be to integrate a batch editing process for FLIR RJPEG images?

Thermoviewer does this, but it doesn't do it based on each image it does it based on a value you input. I'd like it to run an "auto-contrast" type function based on the extent of each images data similar to how FLIR tools does it. Problem is, FLIR tools has 0 batch editing and automatically watermarks each picture you do adjust - so a macro is out of the question

Hello,
here is a test version, it include a first approach for Batch processing:
https://drive.google.com/file/d/1Z60y5u7k6e_cv77oEYWHYN7G18l6hfHM/view

Goto "Frunctions" area on left and to "Batch processing".
Writing a FLIR image is a not existing mechanism yet.
But open->autoscale->extract frame will work. the Export settings for images are set in Functions->Export: Images

suggestions are welcome.
best wishes

Hi Joe,

Thank you for creating this new dimension for making use of a phone IR camera. I wonder if you could give me a tip please to get ThermoVision 1.9.0.0 under Win 10 to show images from my Seek Thermal Compact (non-PRO)?

I can stream images perfectly with SeekOFix v0.4, so I think the WinUSB drivers are OK.

Using the Seek Thermal device in ThermoVision I can connect to the camera and see FW revision and Serial, but cannot receive frames (the Start Streaming button is red). I tried 1.8.0.0 but the symptom is the same.

Using device TCamDll2 the DLL log shows connection and stops after successfully getting resolution.

Thanks in advance, Andrew.

Seek Thermal.NET V006 works fine

aentwistle · « **Reply #234 on:** March 04, 2019, 01:12:06 pm »

Hi, I changed to the Compact Pro and it works well with ThermoVision 1.9.0.0 using TCamDll2

Thanks,

Andrew.

Hello,

i have no win10 device here, only a win8.1 but i need a bit to reproduce the problem to see whats going on.
Does the Pro also work with TCamDll1 and the regular "Device: Seek Thermal" ?
Does the non pro work with TCamDll 2?

best wishes

aentwistle · « **Reply #236 on:** March 04, 2019, 06:19:52 pm »

Hi Joe,

I sent the non-Pro back in exchange for the pro so cannot do any further tests, but I can confirm that I could not get the the non-Pro to stream in Thermovision with either DLL or the device Seek Thermal. The Pro streams OK with TCamDll2 and TC_SeekThermal.dll. I am now happy using Thermovision with the Pro thanks.

Cheers,

Andrew.

Hi Joe,

I have a problem with your software. When I try to export des IR image with the measurments I have an offset in the text and it's sometimes difficult too read the informations.

Also, when the resolution get higher, the legend at the right change and become too tiny. Any idea about these problems ?

Btw, I'm on Windows 10

Regards,

Guillaume

I have not mouch experience with Win10, but i know there is a screen setting for the size of the relative text size.
i guess your setting is not 100%... maybe you have 125% or 150% right?
Try to set to 100%.

Yes... the size is relative to the image size, this led to big steps on small images and too much steps on large images.
your image resolution look really big, but its just interpolated source image right?
Anyway. it would be better to have more access to the size of the palette bar, its on my "todo list"

Joe,

your software is very helpful for us. any chance and/or place to tip you for your work ?

Doe this software work with Opgal Therm-App cameras too?

not yet, i have no therm-app to explore.
Store the Therm-App images with an radiometric frame?

Thanks I will give it a try. SO radiometric files should work on this app? I have a Mac so can't currently use the software.

Hi everyone,
I would like to know if my SEEK SHOTPRO is compatible with Thermovision_JoeC software and if someone can explain how to use this software.
I've already tried it but it doesn't seem to work.
Thank you

Hello,
i just see some sample images of the new seek series, i dont know more about it.
there is no support yet, sorry.
not sure seek store radiometric data in the images, but if you send 2-3 images i can look inside.
best wishes

Vipitis · « **Reply #245 on:** May 02, 2019, 10:39:18 pm »

They explicitly decided not to output radiometric images https://support.thermal.com/hc/en-us/articles/360002053640-How-do-I-get-captured-images-off-of-the-device-?mobile_site=true

Maybe someone can go really deep into the app and pull them out, but not likely.

majoma · « **Reply #246 on:** May 03, 2019, 05:31:29 am »

Yes, this is true, but in the camera, when you take photo, there is a jpg file (flat no radiometric) and a .hir file (this Shuld be radiometric). If some software can read .hir file.

please upload 2-3 of this .hir files (maybe you need to pack into a .zip).
i will look at it.

majoma · « **Reply #248 on:** May 05, 2019, 04:35:47 pm »

This is the file.
Thank you very much!

joe-c · « **Reply #249 on:** May 05, 2019, 09:44:19 pm »

Hello,
interesting... a 2.5Mb file compressed to 0.8Mb.

i attach what i found. seems to be a stored jpg file with attached raw frame and visual frame (with Y map followed by color data).
