Extract all Pitch, Yaw and Roll EXIF information from JPEG using Python PIL

Extract all Pitch, Yaw and Roll EXIF information from JPEG using Python PIL

I have a series of JPEGS captured during an aerial patrol. These JPEGS have metadata stored within JPEG, this metadata includes the GPSInfo and other data.

I am trying to extract this information into a format I can use (csv etc.). I am also going to try and implement this in a Python script that will run on a shared virtual machine, possibly in FME.

I am able to run the Python PIL library and extract out much of the information I need. See below:

import PIL.Image

import PIL.ExifTags

from PIL import Image, ExifTags

from PIL.ExifTags import GPSTAGS

from PIL.ExifTags import TAGS

from os import walk

import os

import pandas as pd

import os

from datetime import datetime

def get_exif(filepath):

image = Image.open(filepath)

image.verify()

return image._getexif()

The following falls under a Main() method

for filename in os.listdir(direct):

if filename.endswith(".jpg"):

print (i)

filepath = os.path.join(direct, filename)#

attribs = []

exif = get_exif(filepath)

fields = ['GPSInfo', 'Model', 'ExposureTime', 'FocalLength', 'Software', 'DateTime', 'DateTimeDigitised']

exifData = {}

for f in fields:

for tag, value in exif.items():

decodedTag = ExifTags.TAGS.get(tag, tag)

if decodedTag == f:

exifData["File"] = filename

if decodedTag == 'GPSInfo':

exifData["Y"] = value[2]

exifData["X"] = value[4]

exifData["Z"] = value[6]

continue

else:

exifData[decodedTag] = value

continue

df = df.append(exifData, ignore_index = True)

i +=1

Extract all Pitch, Yaw and Roll EXIF information from JPEG using Python PIL

Is there a way to have the PIL library return these values for Yaw, Pitch and Roll?

I cannot use the commandline on the machine I want to deploy this and I cannot add any new transformers to my FME Installation on this machine.
