flirimageextractor's Issues

Obtaining RGB in the same size and visual field as thermal

Hello, we are trying to create a mask using the RGB picture and then superpose this mask with the thermal data. However, the thermal image has a smaller visual field and is smaller than the extracted RGB one. Is there any way to know which transformations need to be applied to the RGB in order to match the thermal one, or to extract the adequate RGB image directly?

Thank you in advance.

What raw input format for an FLIR video do you support?

I have raw ats videos. Do you support them as an input? How can I feed them and extract both images and thermal values of each pixel for a video? The video is saved as ats by ResearchIR software.

the exception should caught and suggestion be offered.

also, if this is a cli program why it would require Tk which is Gui widget?

Flir Lepton

Can this version of the library work with the Flir Lepton 3.5?

Cannot find file specified

No matter where I put it, I cannot get the program to open the .jpg file. I have used Flir One pro and Flir C3.

filenames containing '.' are not parsed properly

Please change this line

thermal_output_filename_array = self.flir_img_filename.split(".")

to e.g. this:

thermal_output_filename_array = os.path.splitext(self.flir_img_filename)

to handle dots in filenames properly. Thanks!

how apply FLIR palettes?

how to apply FLIR palettes? for example iron.

can i only read the temperature data in my select box

RGB image initialisation

Is there a reason the initialisation of the RGB image (line 94 of build/lib/flirimageextractor/init.py) is commented out?

Use global range for term value

Congratulations for this library, I use it to convert my flir image fff to jpg
Is it possible use a range of global value instead of use min,max data get from file?

I need to process more flir data captured in different day

Many thanks

The logging library doesn't get installed with FlirImageExtractor

I updated FlirImageExtractor but the logger library didn't get installed as a dependency.
It can be solved by installing manually.

pip install error: mistune has no attribute 'BlockGrammar'

I see the pip lib has the version 1.5.3
Since I am new, I tried to install the latest version of the flirimageextractor, but it fails.
The error message like below.

math domain error

When trying to get temperature reading for multiple images getting math domain error. Can anyone help with this issue

Image captured by PureThermal 2 - FLIR Lepton

I captured image from Pure Thermal - FLIR Lepton camera, but its not working with FlirImageExtractor. Its throwing the following error:
KeyError: 'RawThermalImageType' And when I run exiftool <flir_image>, lots of meta-data are missing? How should I do to capture image with full image meta-data details?
Any kind of suggestions / references will be helpful to me.

When I run exiftool <on-my-image>, its just showing the following data:

saving rgb images as well is missing

I propose adding this to the end of save_image():

    if self.rgb_image_np is not None:
        img_rgb = Image.fromarray(self.rgb_image_np)
        if bytesIO:
            bytes = io.BytesIO()
            img_rgb.save(bytes, "jpeg", quality=100)
            return_array.append(bytes)
        else:
            rgb_output_filename_array = os.path.splitext(self.flir_img_filename)
            filename = (
                rgb_output_filename_array[0]
                + "_rgb"
                + rgb_output_filename_array[1]
            )
            if self.is_debug:
                logger.debug("Saving Rgb image to:{}".format(filename))

            img_rgb.save(filename, "jpeg", quality=100)
            return_array.append(filename)

using FlirImageExtractor with Pydroid. ExifTool as itself cannot be installed

I would like to use FlirImageExtractor but despite there is an exiftool app for android, the script looks for the executable in path folders as if it was run in windows.
This is the simple script i would like to get running before going further improving the script in my computer.

I would truly appreciate if someone could provide any useful tip. Best regards

import flirimageextractor
from glob import glob
import os

flir = flirimageextractor.FlirImageExtractor()
files = glob("C:/FLIR/*.JPG")
files = [texto.replace("\", "/") for texto in files]
files = [os.path.basename(file) for file in files]
for file in files:
try:
flir.process_image('FLIR/'+file)
flir.save_images()
thermal=flir.get_thermal_np()
flir.plot()
except Exception as e:
print(f"Error al procesar el archivo {file}: {e}")

cannot find file error

This error might come on windows.

Multiple images

This takes only one input file and gives the output csv file , how to automate this for multiple images in a folder and get separate csv files with temperature readings for each of them
