please can you try dropping an image in here https://onlineexifviewer.com/ if that shows no exif, please download your image direct from google photos web and check again.
Thanks
I am capturing the image from the webcam, and after that, I am trying to get the location. when I drop the image on https://onlineexifviewer.com/ it has no exif data too. I don't know how to solve it.
this is the code for image capturing cap = cv2.VideoCapture(0) images = [] global imgname
if cap.isOpened(): ret, frame = cap.read() #capture a frame from live video
frame = frame[120:120+250,200:200+250, :]
l_b=np.array([0,230,170])# lower hsv bound for red
u_b=np.array([255,255,220])# upper hsv bound to red
#check whether frame is successfully captured
if ret:
# continue to display window until 'q' is pressed
while(True):
if cv2.waitKey(1) & 0XFF == ord('a'):
# Create the unique file path
imgname = os.path.join(ANC_PATH, '{}.jpg'.format(uuid.uuid1()))
# Write out anchor image
images.append(imgname)
cv2.imwrite(imgname, frame)
# Collect positives
if cv2.waitKey(1) & 0XFF == ord('p'):
# Create the unique file path
imgname = os.path.join(POS_PATH, '{}.jpg'.format(uuid.uuid1()))
images.append(imgname)
print(imgname)
# Write out positive image
cv2.imwrite(imgname, frame)
cv2.imshow("Frame",frame) #show captured frame
#press 'q' to break out of the loop
if cv2.waitKey(1) & 0xFF == ord('q'):
break
#print error if frame capturing was unsuccessful
else:
print("Error : Failed to capture frame")
# Release the webcam
cap.release()
# Close the image show frame
cv2.destroyAllWindows()
else: print("Cannot open camera")
Just to be clear here:
yes, I am asking about my project. yes I am openCV to capture images from a webcam
I'm afraid you have come to the wrong place as I have never used OpenCV. I'm of the opinion that it does not create exif because it treats images as NumPy arrays. So you would need to construct your own metadata. This article seems to confirm my thoughts https://learnopencv.com/what-is-exif-data-in-images/
Thanks for sharing the article.
from PIL import Image from PIL.ExifTags import TAGS
this is a test for our live video on fB
open test
def get_exif(filename): image = Image.open(filename) print(image) image.verify() print(image.getexif()) return image.getexif()
extract the exif data from image file
exif = get_exif(imgname) # included image
Loop through tags for print out
if exif: for k, v in exif.items(): print(str([TAGS.get(k)]) + "\t" + str(v))
why exif is empty? I have changed so many images but still the same result.
