3. 文献调研综合结果

通过对2007年至2025年间相关文献的综合调研,我们可以看出:

  1. 重要里程碑

    • 从早期的图像配准与SIFT加速器,到后期针对视觉SLAM、点云匹配与三维重建的专用芯片,加速器设计经历了从单功能模块到系统级集成的转变。

    • 代表性工作包括密歇根大学的全视觉CNN-SLAM处理器、MIT的Navion VIO加速器、以及近期针对3D点云语义分割和点云匹配的专用设计,如KAIST的低功耗图卷积处理器和韩国蔚山的3D点云匹配处理器。

  2. 性能、面积与功耗的持续提升

    • 通过算法简化、流水线并行、存储层次重构以及新型器件应用,各阶段产品在实时性、能效和面积利用率方面均有显著突破,部分设计的能效甚至提升数十倍。

    • 尤其在低功耗设计上,许多作品已实现毫瓦级功耗下支持高清、实时处理,为边缘设备和无人机等应用提供了关键技术保障。

  3. 数据结构—算法—架构深度耦合优化的不足

    • 尽管当前方案在各自领域取得成功,但普遍存在的问题是不同任务间的数据重用不足、硬件资源分配不均以及针对特定场景的适应性有限。这为进一步研究提出了挑战,也凸显了新一代算法硬件协同设计的必要性。

  4. 科学意义与应用前景

    • 本领域的发展不仅推动了视觉与点云处理技术在自动驾驶、机器人和增强现实等前沿应用中的落地,也为跨模态数据融合、边缘智能计算以及新材料器件的应用提供了技术支撑。
