2.1 Sphere Tracing(球追踪技术) 使用球追踪(Sphere Tracing)技术来渲染一个带有符号距离场(Signed Distance Field)的场景,并从中获取屏幕空间法线图(Screen Space Normal Map)和深度图(Depth Map)。其中关键要素如下: Signed Distance Field(符号距离场):符号距离场是一种表示空间中对象表面的方式。对于每个点,它的...
Yet, traditional Neural Radiance Field (NeRF) methods face challenges such as sampling single points per iterationand requiring an extensive array of views for supervision. UAV videos exacerbate these issues with limited viewpoints and significant spatial scale variations, resulting in inadequate detail ...

A field is a quantity defined for all spatial and/or temporal coordinates.(场是由空间或者时间定义的量)
Learn more: How do neural radiance fields work? The termneural radiance fielddescribes the different elements in the technique. It isneuralin the sense that it uses a multilayerperceptron, an older neural network architecture, to represent the image.Radiancerefers to the fact that this neural netw...
scene reconstruction is achieved from the fusion of multiple synthesized novel depth views. This is enabled by our spherical-decoder, which allows hallucination beyond the input frame field of view. Thorough experiments demonstrate that we outperform all baselines on all metrics for novel depth views ...
