Open-set 3D Object Detection

no code implementations2 Dec 2021 Jun Cen, Peng Yun, Junhao Cai, Michael Yu Wang, Ming Liu

The first step is solved by the finding that unknown objects are often classified as known objects with low confidence, and we show that the Euclidean distance sum based on metric learning is a better confidence score than the naive softmax probability to differentiate unknown objects from known objects.

Incrementally learning these OOD objects with few annotations is an ideal way to enlarge the knowledge base of the deep learning models.

Although the model is trained using only RGB image, when changing the background textures, it also performs well and can achieve even 94% accuracy on the set of adversarial objects, which outperforms current state-of-the-art methods.
