Point Cloud Optimization Using PPO and V-PCC

Project Overview

This project optimizes the transmission of point cloud data in a multi-user environment. It leverages Proximal Policy Optimization (PPO) and V-PCC (Video-based Point Cloud Compression) technologies to dynamically optimize user grouping, layered transmission, and video quality allocation. The aim is to balance bandwidth utilization and user experience (QoE - Quality of Experience).

Features

1. Compression: Uses V-PCC to compress point cloud data into Base Atlas and Auxiliary Atlas.
2. Dynamic Optimization: Applies PPO reinforcement learning to optimize:
   • User grouping based on FoV, device performance, and bandwidth.
   • Base Atlas resolution and Auxiliary Atlas quality allocation.
3. Baseline Comparison: Includes three baselines:
   • Static Transmission: Fixed quality for all users.
   • Bandwidth Priority: Allocates quality based on bandwidth.
   • No Optimization: Directly transmits data based on user requirements.
4. Metrics: Evaluates strategies based on:
   • QoE (Quality of Experience).
   • Bandwidth Utilization.
   • Transmission Delay.
   • System Throughput.
