Abstract: Provided is an electronic apparatus for lightweight of a three dimensional (3D) object detection model based on knowledge distillation, the electronic device including: a backbone network module configured to perform knowledge distillation such that a first feature map of a teacher network and a second feature map of a student network extracted through input point cloud data are made identical to as each other; and a self-attention module configured to acquire a plurality of pieces of detection information from a plurality of detection heads for 3D object detection, respectively, using the first feature map and the second feature map, and perform knowledge distillation using a relation-aware self-attention calculated based on the acquired plurality of pieces of detection information.
