Multiple registration results for one sequence #18

Closed AfterJourney00 closed 1 year ago

AfterJourney00 commented 1 year ago

Hi, thank you for your excellent work!

I found that some sequences like Date02_Sub02_monitor_move and Date04_Sub05_monitor have multiple registration results in behave-30fps-params-v1/(e.g. behave-30fps-params-v1/Date02_Sub02_monitor_move and behave-30fps-params-v1/Date02_Sub02_monitor_move2). I wonder what's the differences between them and which one should be treated as the ground truth.

Thanks a lot!

Hi,

This is due to the difficulty of registrating the intermediate frames between these two parts. In these frames, the object PC is too incomplete and it was not possible to obtain registration over the full sequence. Hence I split it into two sequences. You can find the correspondence from the parameters to RGBD images by the 'frame_times' stored in each npz file. The frame time list should have the same length as the number of parameters in each npz file.

Best,
