Instant-NGP通过fully-fused CUDA kernels来减少带宽和计算的花费。 计算机图形原语(Computer Graphics Primitives)是通过数学函数表达来对场景表面进行编码的一种图形基础。数学表达的质量和性能对于视觉效果至关重要,最理想的情况是有一种既高效快速又紧凑,同时还能够捕捉场景的高频信息(即局部特征)的
论文地址nvlabs.github.io/instant-ngp/assets/mueller2022instant.pdf 文章重点为第三节,多分别率哈希编码,原文不太好理解,原理很简单。 其中, L即为多分辨率,此处所说的多分辨率,是将原图按照N值进行多尺度等分 T为单一分别率图像哈希表大小 F为每个顶点及entity的特征维度 Nmin 是上面所说等分N值的最小值...
Instant-NGPneural radiance fieldsSfMSoybeans have been one of the most significant crops in food security and agricultural economics in recent years. 3D reconstruction of soybean plants can greatly contribute to agricultural research and breeding. Plant structures and morphology can be utilized to ...
The final stage involved the use of Instant-NGP. Multi-resolution hash encoding was performed on the images containing pose information. These encoded images were processed through a small multilayer perceptron, particularly for efficient 3D reconstruction. Experimental results...
