第十三个:Collect3D,这一步其实很简单,就是用于pipeline的最后一步,其根据我们初始化时候给它指定的meta_keys,为了我们具体的任务搞出来所需要的整顿好,把dict中我们已经存下的这么多东西进行自定义的收集,放入img_metas这个key中,其是一个包含了我们所收集的内容的DataContainer。 """Collect data from the loader...

训练的时候,首先进入parse_data_info函数,然后调用parse_ann_info函数。其中的参数info是 读取的 pkl 格式。其中,METAINFO 根据自定义数据集的实际类别情况修改。下面 gt_bboxes_3d 也根据实际情况自行编写: gt_bboxes_3d=LiDARInstance3DBoxes(ann_info['gt_bboxes_3d'],box_dim=ann_info['gt_bboxes_3d...
The metainfo has been changed to lowercase since#9469. On the custom dataset, use lowercase letters for keys in the dictionary instead. For example, in the jupyter notebook demo, change cfg.metainfo={'CLASSES': ('balloon', ),'PALETTE': [ (220,20,60), ] } ...
