Hi! Thank you for releasing a wonderful work. I have a few questions regarding the extrinsics & intrinsics processing in CustomNuScensDataset
and data pipelines, and hope you could help answer:
>>> np.array([extr[-1,:].round(2) for extr in extrinsics])
array([[ 0.01, -0.33, -0.48, 1. ],
[ 0.05, -0.34, -0.63, 1. ],
[ 0.09, -0.33, -0.54, 1. ],
[-0. , -0.28, -1. , 1. ],
[-0.24, -0.24, -0.44, 1. ],
[ 0.08, -0.27, -0.49, 1. ]])
# step over to another sample
>>> np.array([extr[-1,:].round(2) for extr in extrinsics])
array([[ 0.01, -0.33, -0.58, 1. ],
[ 0.11, -0.34, -0.68, 1. ],
[-0.02, -0.33, -0.61, 1. ],
[-0. , -0.28, -0.96, 1. ],
[-0.23, -0.24, -0.44, 1. ],
[ 0.14, -0.27, -0.47, 1. ]])
>>> info['cams'].keys()
dict_keys(['CAM_FRONT', 'CAM_FRONT_RIGHT', 'CAM_FRONT_LEFT', 'CAM_BACK', 'CAM_BACK_LEFT', 'CAM_BACK_RIGHT'])
>>> info['lidar_path']
'./data/nuscenes/samples/LIDAR_TOP/n015-2018-07-18-11-50-34+0800__LIDAR_TOP__1531885881798485.pcd.bin'
Looking forward to hearing from you. Thanks in advance!
