Nowadays, pre-training big models on large-scale datasets has become a
crucial topic in deep learning. The pre-trained models with high representation
ability and transferability achieve a great success and dominate many
downstream tasks in natural language processing and 2D vision. However, it is
non-trivial to promote such a pretraining-tuning paradigm to the 3D vision,
given the limited training data that are relatively inconvenient to collect. In
this paper, we provide a new perspective of leveraging pre-trained 2D knowledge
in 3D …
