EVO Max 4T Metadata issues

dspiegel · Oct 31, 2023

I am trying to upload photos into Pix4dmatic and its getting an error. This is due to the camera calibration being incorrect. I have attached the metadata from both a DJI and Autel and the Autel data is missing a bunch of information. Anyone have any success flying a photogrammetry mission? Pix4D provided the following:

I hope Autel fixes this issue.

Find a Metadata editor that does batch changes.
Change Horiz CS to EPSG:4326 to indicate WGS84

Don't change the original images. Copy them and then edit the metadata.

This is my guess on this. All drones (Non-RTK/PPK) will use WGS84 and the correct EPSG would be 4326.

I am surprised that Pix4D Support didn't tell you to do this.
They are usually very helpful.

They told me to contact the manufacturer to get help removing or replacing the tag. I didn't know I could edit the metadata myself as you proposed.

They identified the issue but didn't clarify what the tag should be.

Out of curiosity, what metadata editor did you use?

There in lies the problem, I used an online free one (Metadata Editor. Change Document and Image Properties Online) to edit one photo which worked. Now I am trying to find a batch editor to edit lots of photos. Do you have one you use that can edit the XMP data? I thought ImBatch would do it but it seems to only do EXIF data.

I have used Metadata +++, but I have never used it to do a batch change.

Here is a Youtube video on doing a batch.

Thank you. Ill try that one out. I wish there was a way to edit it in the drone itself so I didn't have to go through this but Autel has been pretty slow in responses.
