Some annotations for labels on GEN1 dataset are wrong

Open JDYG opened this issue 5 months ago • 2 comments

The ground truth annotation for ./Gen1_Automotive/test/17-10-12_16-51-41_2989500000_3049500000_td.dat in GEN1 dataset is wrong.

The code for loading this label is:

event_path ='./Gen1_Automotive/test/17-10-12_16-51-41_2989500000_3049500000_td.dat'
bbox_fname = event_path [:-7] + '_bbox.npy'
label_path= PSEELoader(event_path)
box_video = PSEELoader(label_path)

total_time = events_video.total_time()
events = events_video.load_delta_t(total_time)
labels = box_video.load_delta_t(total_time)

The extracted results for labels are:
