2023年1月4日 · PETR develops position embedding transformation (PETR) for multi-view 3D object detection. PETR encodes the position information of 3D coordinates into image features, producing the 3D position-aware features. Object query can perceive the 3D position-aware features and perform end-to-end object detection.

2022年3月10日 · In this paper, we develop position embedding transformation (PETR) for multi-view 3D object detection. PETR encodes the position information of 3D coordinates into image features, producing the 3D position-aware features. Object query can perceive the 3D position-aware features and perform end-to-end object detection. PETR achieves state-of-the-art …

Petr Evgenyevich Yan (Russian: Пётр Евге́ньевич Я́н [6], romanized: Pyotr Yevgenyevich Yan; born 11 February 1993) is a Russian professional mixed martial artist. He competes in the Bantamweight division of the Ultimate Fighting Championship (UFC), where he is a former UFC Bantamweight Champion .

2022年6月2日 · In this paper, we propose PETRv2, a unified framework for 3D perception from multi-view images. Based on PETR, PETRv2 explores the effectiveness of temporal modeling, which utilizes the temporal information of previous frames to boost 3D object detection. More specifically, we extend the 3D position embedding (3D PE) in PETR for temporal modeling. …

petr想实现：是否有可能将二维特征从多视图转换为3d感知特征（创新点）。 具体做法：PETR通过3D Position Embedding将多视角相机的2D特征转化为3D感知特征，使得 object query 可以直接在3D语义环境下更新，省去了参考点反投影以及特征采样两个步骤。
