Read AEDAT4 file

[IsmailAM1999]

Hi, thank you very much for your work.

I tried with a sequence of MVSEC and it works fine, and I want to try with raw events from a mono-type event camera (.aedat4), is there any way to read this type of extension?

I also want to try the approach to format source data in hdf5, can you guide me through the hierarchical structure? And what script should I use/modify to accept this type of data?

Thanks in advance for your time and help.

Event camera : DVXplorer Mini

Actually my private code has the interface to read aedat and hdf5 files as you requested. I'm thinking of how to merge it into the repo. Give me some time for preparation.

Thank you very much for your quick response. I am looking forward to your merge, and I will be pleased to test it out.

We can keep this issue open to remind me

Were you able to include this reader in the codebase?

@nikky4D I hope to have time to do during this winter holiday.
If you are in a hurry, you could try my other library. Will be something like:

from evlib.codec import fileformat

# Setup iterator reader
file_path = "./sample.aedat"
ev_iter = fileformat. IteratorAedat4Event(file_path)

# Define key mapping for the hdf5 file
data_keys = {"x": "raw_events/x", "y": "raw_events/y", "t": "raw_events/t", "p": "raw_events/p"}

# Convert
output_file_name = "event.hdf5"
fileformat.convert_iterator_access_to_hdf5(ev_iter, output_file_name, data_keys)
print(f"Finished conversion: {output_file_name}")
