职位描述
项目描述:
得物 App 正在打造下一代商品 3D 展示与虚拟体验生态,现招募 3DGS 算法实习生,专注于基于物体的 3D Gaussian Splatting 重建质量优化研究。你将参与解决奢侈品、潮鞋、服饰等商品 3D 重建中的几何精度、纹理细节、渲染效率等核心问题,直接推动 3D 技术在电商场景的规模化落地,让用户获得更真实、更沉浸的线上购物体验
职位要求:
1. 3DGS 质量优化研究
- 针对商品物体(尤其是小尺寸、高细节、反光材质)的 3DGS 重建流程进行系统性优化,提升几何精度与纹理还原度
- 研究并实现伪影抑制技术(如悬浮噪点、边界模糊、表面缺口),解决商品重建中的常见质量问题
- 探索自适应高斯分布策略,实现复杂区域密集建模、平坦区域稀疏建模的智能分配
2. 算法开发与验证
- 复现并改进前沿 3DGS 优化算法,适配得物商品重建场景
- 设计量化评估体系(PSNR、SSIM、LPIPS、几何误差等),客观衡量重建质量提升效果
3. 工程化落地辅助
- 与工程团队协作,将优化算法集成至得物 3D 重建管线,平衡质量与效率
- 针对移动端 / 网页端渲染需求,探索轻量级 3DGS 表示(如参数量化、稀疏编码),降低部署成本
- 参与 3D 商品库建设,提供算法支持保障大规模重建质量一致性
职位要求
基础要求
1. 2028届及以后毕业,本科及以上学历在读,计算机科学、数学、自动化、软件工程等相关专业,有 3D 视觉或图形学基础
2. 熟练掌握Python,熟悉PyTorch/TensorFlow等深度学习框架,具备算法实现能力
3. 了解计算机视觉基础(相机标定、多视图几何、特征匹配)和计算机图形学概念(渲染管线、光线追踪)
4. 良好的英文文献阅读能力,能快速跟进 CVPR/ICCV/ECCV/SIGGRAPH 等顶会 3DGS 最新进展
5. 具备问题拆解能力,能独立分析并解决算法开发中的技术挑战
加分项(满足 1 项及以上优先)
1.有3DGS/NeRF 相关项目经验,熟悉 3DGS 核心流程(高斯初始化、致密化、优化、渲染)
2.发表过 3D 视觉 / 图形学领域顶会论文或有相关竞赛获奖经历
3.掌握C++,有 CUDA/OpenCV/Open3D 开发经验,能优化算法性能
4.了解商品 3D 重建业务(如摄影测量、激光扫描),有电商 / AR/VR 行业实习经历
5.具备渲染引擎知识(如 Unity、Unreal),能评估算法在实际应用中的表现
本项目为得物研究型实习生项目。该项目岗位最低实习时长为6个月,岗位非纯业务开发岗位,主要目的为发表顶级期刊。
