Abstract: Highlights•We identified the issue of discontinuous receptive fields (DRF).•The first model to address DRF with a point-based backbone is proposed.•DRF-SSD achieved a 1.1% improvement in mAP3D<math><mrow is="true"><mi is="true">m</mi><mi is="true">A</mi><msub is="true"><mrow is="true"><mi is="true">P</mi></mrow><mrow is="true"><mn is="true">3</mn><mi is="true">D</mi></mrow></msub></mrow></math> compared to the art models.•The designed HED and HT modules have excellent plug-and-play capabilities.
