Advances in 3D pre-training and downstream tasks: a survey
摘要
Recent years have witnessed a signifcant breakthrough in the 3D domain. To track the most recent advances in the 3D field, in this paper, we provide a comprehensive survey of recent advances in the 3D feld, which encompasses a wide collection of topics, including diverse pre-training strategies, backbone designs and downstream tasks. Compared to the previous literature review on point cloud, our survey is more comprehensive. Our survey consists of the 3D pre-training methods, various downstream tasks, popular benchmarks, evaluation metrics as well as several promising future directions. We hope the survey can serve as the cornerstone for both academia and industry.
