XRNeRF 将整个代码框架进行了模块化设计,最大程度地提升了代码的可复用性,便于研究者对现有代码进行阅读和修改。通过分析现有的 NeRF 类模型方法,XRNeRF 设计的具体模块流程如下图所示:模块化的优势在于,假设我们需要修改数据格式,那只需要修改 Dataset 模块下的逻辑,假设我们需要修改渲染图像的逻辑,那就只需要...
精准地使用渲染技术获取不同视角图片和相应的准确的相机位姿文件。转载一篇git,记录一下,很好用,作者还出了视频:GitHub - maximeraafat/BlenderNeRF: Easy NeRF synthetic dataset creation within Blender 输出数据可以直接挂载到NeRF源码对应的路径下进行实验。

模块化的优势在于,假设我们需要修改数据格式,那只需要修改 Dataset 模块下的逻辑,假设我们需要修改渲染图像的逻辑,那就只需要修改 Render model 模块。 3. 标准数据处理管线 针对NeRF 类算法数据预处理较为复杂和多样的问题,XRNeRF 提供了一套标准数据处理流程。其由多个数据处理操作串行得到,仅需要修改 config 配置文...

This paper introduces DatasetNeRF,a novel approach capable of generating infinite, high-quality 3D-consistent 2D annotations alongside 3D point cloud segmentations, while utilizing minimal 2D human-labeled annotations. Specifically, we leverage the semantic prior within a 3D generative model totrain a ...
