content: Hi, began with a silly thought, I did a google search, and surprisingly there's already people do it for visible-light cameras, examples:https://petapixel.com/2020/10/27/this-external-lidar-device-can-add-continuous-autofocus-to-any-camera/https://hackaday.com/2014/11/12/an-external-autofocus-for-dslrs/Since the distance is not sensed by the camera they operate on, they can be used on any camera, including thermal ones.Auto focus is so rare on thermal cameras, anybody want give these a try?

content: I used National Panasonic video cameras in the 1980’s that employed ultrasonic distance measurement and motorised focus adjustment. These worked OK but I think the issue may be the shallow depth of field that thermal cameras can have. A shallow depth of field is very demanding on an auto focus system that does not analyse the actual image being captured.The thermal cameras that I have with real auto focus use the image being collected and even those expensive cameras are not perfect at getting the focus right every time. Auto focus on a thermal camera is not easy, no matter how you approach it.

content: Quote from: bap2703 on September 03, 2021, 06:48:18 pmThat is certainly how I set up the Argus cameras, but for fire users infinity was not of much interest anyway so at 2m and good for 4 - 1m was more like it. The more recent cameras with shorter focal length lenses are 4m and good 2m to infinity.The 25° field of view ones (13mm f/1.4 on a 320x240 25u sensor) were set to 8m and were acceptable from infinity to 4m. That said if I knew I was after longer distance images I'd tweak it in a fraction.

It seems like you would be getting 2 kinds of camera in one if I am reading it correctly?Seems like it uses some kind of fusion image enhancement where it uses both lens to get a better image, kind of like an overlay of both pictures. I would guess this would make the previous model tiapan obsoleteinterested in seeing some review footage.is this something done with other manufacturers with success?

It was the Infiray recommendation for fever screening due to the low NEDT < 40mK and thermal resolution of 388x288.When I aimed at the sky at night it was pixelated.

Or at least hik vision claims this in their websiteis this true?

A screamer of a deal on a modern VGA core - Page 1

timestamp: August 12, 2021, 08:37:46 pm
content: I've been meaning to get a more modern VGA format high resolution thermal core for years at this point but the $2K starting price is a hard pill to swallow.Eventually my gut feeling about the demand spike and crash of the thermal monitoring market due to the coronavirus and kiosk temperature checks would eventually lead to a mass sell off of systems at bargain basement prices.This was one such system, a I snagged for well under $1k.RIPPIN good deal on its own, but diving inside the deal became even better(These things retail for around $20K according to manufacturer).A quick removal of the cover and it's pretty much exactly what I expected inside, Core block style IR (with a normal COTS ribbon cable data bus), board level EO, and a Hisilicon based IP camera board(though it does have an intriguing dedicated AI processor SOC daughterboard connected over I think PCIE).[ Specified attachment is not available ][ Specified attachment is not available ]Quick power up shows the BNC on pigtails is non-output, disabled in software sadly, but it spits out two RTSP ONVIF streams(EO/IR) and IR is in 1:1 format, VGA 25Hz. Quality of thermal video is excellent, no overdone digital enhancement or weird amplification in default rainbow color map.Pulling core out shows it's a standard type, M34 format lens attachment (HOORAY!) and a normal mezzanine connector on the back to a carrier board to ribbon. More investigation has this camera positively ID'd as a Dali D8X3C camera which is even better news because a quick email over to their support line and I got the documentation on the core, video format and command/control interfaces.[ Specified attachment is not available ]Attached at end of post are some sample captures off the RTSP stream as I haven't made an interface board or teamed up with the friends to make a better video interface over USB or similar.

timestamp: August 21, 2021, 12:04:46 pm
content: Not specific to the FLIR images, but ImageJ can import any sort of raw format via its' interface if you can work out how to set it up. That usually needs you to know if there are headers, line padding, big/little endian (for 16 bit), but as it will always try it should only need a little experimentationUltimately you can import/export a 'text image' where the pixel values are simply a .csv file, which can be used to do some image processing in a spreadsheet.Bill

timestamp: August 21, 2021, 05:48:58 pm
content: As Bill W mentions, not familiar with any specific plugin. Every camera vendor has their own way of doing things. Best thing is if you can access the uncompressed raw digital data. If not, then hopefully there is a way to export to an uncompressed grayscale file format (TIFF or PNG). Those open natively to ImageJ by just dragging and dropping. If RAW, then you have to import every time with selecting all the things that Bill W states plus the image size (row / column).

At this time, Seek Thermal does not offer post-processing software for its OEM cameras. Moreover, please note that Seek's hand-held products (branded goods) do not contain radiometric data and as such cannot support post-processing analysis."Andy.

timestamp: August 19, 2021, 06:34:34 pm
content: This is correct. The Reveal series do not save true Radiometric image files. They save an image file that contains metadata detailing selected spot temperatures only. The Reveal Pro does offer a “Radiometric mode” but this relates to the way that the image is presented to the user. The two options are non-Radiometric RGB that has image enhancement applied that can degrade image Radiometric accuracy. The other option is Radiometric mode that does not apply the “pretty picture” image enhancements that degrade the RGB modes accuracy.The Reveal camera holds saved images in its flash memory where they may be accessed via the cameras built in viewer or using a standard photographic image viewer via USB link to a host computer. There is no computer interaction possible with the Reveal series beyond Mass Memory Storage access mode.

FLIR I50 with empty \FlashFS - Page 1

timestamp: August 03, 2021, 01:05:46 am
content: Hi. I recently bought a non-working flir i50 for less than $50 (lol). Filezilla showed several broken files in the \system directory, so I installed the total commander on the device, and then loaded the Windows CE GUI and formatted \FlashFS. After that I had the opportunity to install the firmware 2.19.1 from the official site using FlirInstallNet and the device started to boot. However, the firmware installed in this way lacks many files, for example, the \system\maps directory is empty, \system\prodresult.rsc is missing too. Thus it turned out that in the absence of calibration files, the device cannot boot normally. I also cannot create new calibration files, the "cases" in the service menu are empty. Therefore, I very much ask someone from the owners of flir ixx/bxx series to copy the contents of the system directory and upload it to the dropbox. Thanks in advance

D- shows ~100mv.Filter and fuses on D+ / D- are good. So i still think issue is in the lightning port assembly.I read on eevblog that Flir 1g2 have setting in to the firmware for the port (L/U). I also found Serial port pinout for 1g2 and looks 1g3 has same header.Haven't tried to connect to Serial yet but will try later today to see output.Decide to ask upfront, how would i update firmware to handle Android.

To avoid this, we plan to record SEQ and then extract the needed frames from it.At the moment, I have been able to split SEQ into FFF images which are correcly interpreted by FLIR Tools and preserve thermal information both in data and header. Nevertheless, I am stuck when trying to get Radiometric TIFFs (exactly the format I would get taking a photo from the drone so I am sure they can be used with processing software) and/or RJPEGs (again, same requirements).I have tried using FLIRPy which claims to include a script that makes just this (get R-TIFFs from SEQ), but the script is just not in the library code.Hope someone can shed a bit of light on this.By the way, I am looking for a programming/scripting approach because I have loads of them to process...Thanks in advance,Jose

content: Hi all,I was quite keen to see how good this unit would be and whilst it "crashed" on power up a few times, when it did power up, I found the screen would "freeze" at random situations when panning across a room.The "freezing" up is really annoying, so it is going back for a refund.Has anyone else had this issue?https://amzn.to/3dkP1haThanks.

content: Did the system lock up with the screen freeze?Sure it wasn't just performing a NUC? The internal shutter activating to perform a NUC will cause the scene to freeze momentarily. Most uncooled thermal imager will do this. Usually the guidance is to power it on and leave it up for several minutes to stabilize. Then the screen freezing will not occur as often.

content: This is how Flir supports their consumer products! This is more than a problem! Youtube posts of Flir One Pro show that the battery discharges on its own in a matter of days and after a month will not accept a charge Mine is doing the exact same thing and is under warranty. I contacted Flir and supplied all the information they requested. I supplied the SN and they said it was manufactured beyond the warranty period and they need proof of purchase so I sent them the PayPal receipt. Now they say they cannot verify a PayPal receipt. Everybody Please be warned about buying anything from this company!

content: Did you purchase the unit from an authorized reseller of FLIR products? This sounds like standard warranty checking behavior, and many companies will no longer warrant an item sold through a dealer they have not authorized, regardless of condition or age. Did they give you an option to have the unit replaced for a fee, as it is out of warranty?

content: Sadly this is not uncommon, as has been stated.FLIR check the production date and if it is beyond the warranty period they check when it was bought, and whether you are the original purchaser. If bought via eBay as a used item you have to rely on “good will” for support. If bought new from a dealer via eBay, your first point of contact will be the company that sold it to you and they will either provide the required documentation to facilitate a return to FLIR or accept the return to them for exchanger/repair. Normal support procedures really.Sadly if you are not the original (1st) purchaser of the product, warranties can be a little challenging as some manufacturers will only honour them for the original purchaser. Nothing unusual in that.There have been cases where a warehouse buys bankrupt or surplus stock in bulk and the warranty clock starts ticking from the day they purchased that stock ! Yep, strange but true. They effectively become the first purchaser of the stock. The basically ‘new’ stock is sold on auction sites like eBay and some may have very little warranty time remaining. In such cases if an item fails it is sent back to the supplier/warehouse who likely take the ‘hit’ and provide a replacement.Fraser

A P7050, as per the serial number label, uses a 160x120 sensor and matches the lens. It is also the remains of a 30Hz camera, slightly surprised as I was expecting it to be 9Hz, but rather academic without the main PCB.Rubber parts are a bit toasted, but camera looks clean. Maybe had a VERY good wash ?The lens is exposed, so no germanium window or seal.It has got a 'video out' LCD PCB in it.It looks like something out of the scrap / repair shop, but I do not think anywhere in India was doing repairs.To be honest at that price I'd build you one.Bill

The ebayer just gets 'interesting stuff' from his contacts in the ship-breakers and sees what he can get.As such, and given how long some items like the P4428 and video receiver have been up there, you'd think he'd take offers more readily.Bill

content: I agree, I was surprised at his lack of interest in my offer. I have seen many ‘ex shipyard’ bits of kit from this seller. Likely costs nothing but the seller prices high in the hope of making a big ‘score’ on an item that is rare or in demand. Good luck to them but I consider that seller relatively high risk to deal with so no longer take an interest in their auctions.

content: Hi, I just bought a Flir SC660. It is complete, except for the two CDs with the QuickReport software and the one that includes the user documentation, in addition to the bluetooth headset (the bluetooth USB dongle remained installed). On the other hand, it does include a HASP pendrive that I assume is used to activate the ResearchIR 3.X suite with which this camera was purchased in 2012 according to the order form that I found inside the hard transport case. The problem is that I cannot use it, since neither the software is included on CD, nor is it available for download on the entire internet. It also doesn't work with the current version 4.4, since apparently only written keys can be updated, not those that are included in a dongle.https://flir.custhelp.com/app/account/fl_swreplacement/Can anyone help me find where to download at least the CD that includes the user documentation, and the ResearchIR 3.X suite to be able to test the dongle? As for the QuickReport software I wouldn't need it, as it was superseded by the Flir Tools suite.I've paid for the camera 1024€ including shipping costs, but I cannot find its initial sale price on the internet or its last sale price when it was discontinued, so I cannot judge whether it's a good purchase or not.I'm also looking for the close-up 0.5x lens with part number 1196683. The rest of the optional lenses for this camera are apparently still available in different online stores, except this one, which is the one that interests me.

I believe the original price was somewhere in the region of €30,000 to €40,000. Lenses were also expensive and seem extremely rare on the secondhand market. I bought separately the 12° lens (which is fabulous) and paid more for that than you spent on the camera - and only found it after a coupe of years of looking. The original list price of the lens was about €10,000 I think.I am still looking for a 7° lens (see attached).If you ever think about selling the camera, please contact me!

content: Don't have one, but things to check:Are your camera and thermometer set to the same emissivity settings?Does the temperature change with angle you look at the surface (is it catching reflections)?Do you have humidity and ambient temperature set in the camera?Have you disabled the NUC shutter?Is there a way to manually force a calibration shutter cycle?Is the camera focused on the target?If your answers are yes, no, yes, no, no, yes, then you're probably doing most of what you can do to keep it accurate. I would check the temperature with a thermocouple or other non-optical means to verify the reading, and then maybe complain to them if it's not meeting spec by this much (they say +-3C or 3% in the datasheet). Seeing the temperature trend downwards suggest to me that it could be related to the self heating of the sensor, which is normal, so does this exhibit the same behavior if it's been running for a bit (10-15 mins) and has temperature stabilized?

content: Chanc3,That is an excellent publication and there is content that will definitely help me to get the best from my SC4000 science cameraMy SC4000 came with a couple of matt black coated aluminium plates that are not discussed in the comprehensive user manual at all. I tried to identify the plates and their intended use on the FLIR web site but no such accessory was listed. I assumed that the plates were intended to be used to set the cameras flat field rather than any temperature calibration function, but why provide two ?Anyway, this new FLIR publication details what the plates are for and how to use them with my cooled camera. See attached picture. there was nothing like this on the FLIR web site. This new publication is very detailed and the page count is the highest yet. It even details the default Temperature ranges and integration times for the cooled camera and that was information I did not previously have and wanted for my own calibration sets. The cutaway images of the cooled imaging core are nice as well. Well done Teledyne FLIRFraser
