Hi @domenzain, I am looking at the dataset shared here.
This dataset tags the Orientation as Horizontal(normal) whereas the images in my camera have Orientation tag with value Rotate 180.
Yes, I agree up is really arbitrary.
But lets say I have two cameras A and B. Camera A writes images with Horizontal(normal) and camera B writes with Rotate 180, how is the data written to the files related?
There are two possibilities that come to my mind:
- Data written to camera B is 180 degree rotated (for reason unknown to me) and exif tags tells me to rotate it after reading to make the picture comparable (orientation wise) to camera A.
- Data written to camera B is similar in orientation to camera A and exif tags tells me that Sequoia was installed on drone such that its head was towards the tail of drone (just like a tag is put in consumer cameras to indicate the orientation of camera while the photo is being taken)
If it is the first case, can I change the settings somewhere that the image is always written with tag Horizontal(normal)?
If it is the second case, then installing the camera on drone such that head is in direction of flight should produce orientation tag with Horizontal(normal). What do you say about that?
