AutoScale_localization

• An officical implementation of AutoScale localization-based method, you can find regression-based method from here.
• AutoScale leverages a simple yet effective Learning to Scale (L2S) module to cope with significant scale variations in both regression and localization.

Visualizations

Red points are the ground-truth. To more clearly present our localization results, we generate bounding boxes (green boxes) according to the KNN distance of each point, which follows and compares with LSC-CNN.
