# ReMAP-DP: Reprojected Multi-view Aligned PointMaps for Diffusion Policy

This repository contains the weights for **ReMAP-DP**, as presented in the paper [ReMAP-DP: Reprojected Multi-view Aligned PointMaps for Diffusion Policy](https://arxiv.org/abs/2603.14977).

## Description

ReMAP-DP is a novel framework synergizing standardized perspective reprojection with a structure-aware dual-stream diffusion policy. By coupling re-projected views with pixel-aligned PointMaps, the architecture leverages learnable modality embeddings to fuse frozen semantic features and explicit geometric descriptors. This ensures precise implicit patch-level alignment, bridging the gap between 2D semantic reasoning and 3D spatial awareness for high-precision robotic manipulation tasks.
