To improve the efficiency of signed distance field computation, combine meshes that represent the static environment. staticMeshes = geom2struct({box1,box2}); staticEnv = staticMeshes(1); staticEnv.Pose = eye(4); staticEnv.Vertices = []; staticEnv.Faces = [];fori = 1:numel(staticMeshes...
grad = gradient(mTSDF,points) returns the gradient computed from distance values in the vicinity of the specified query points in the truncated signed distance field (TSDF). grad = gradient(mTSDF,points,InterpolationMethod=interp) specifies the method to use for interpolating the distance field.Inp...
Signed: Voxels outside the surface have positive distances, while voxels inside the surface have negative distances. This allows the representation of solid objects. The distance field represents a gradient that shifts from positive to negative as it crosses the surface. ...
truncated signed distance functions 在计算机图形学中,截断的带符号距离函数(Truncated Signed Distance Function,TSDF)是一种用于三维重建和表面重建的技术。TSDF通过将每个像素的最近点与表面之间的距离作为该像素的颜色,可以生成高质量的表面重建结果。 TSDF的基本思想是将每个像素周围的区域划分为三个部分:内部、外部...
Truncated Signed Distance Function(TSDF)是一种用于表示三维空间中物体表面的数据结构。它将空间划分为一个规则的体素网格,并为每个体素存储一个有符号距离值。这个距离值表示该体素中心到物体表面的距离。TSDF将距离值截断在一定范围内(通常是[-1, 1]),以减少存储和计算的开销。 TSDF在计算机图形学或相关领域中的...
Voxblox is a volumetric mapping library based mainly on Truncated Signed Distance Fields (TSDFs). It varies from other SDF libraries in the following ways: CPU-only, can be run single-threaded or multi-threaded for some integrators Support for multiple different layer types (containing different ...

3、如果第i帧深度图像(u,v)处的深度值D(u,v)不为零,则比较D(u,v)与体素相机坐标V(x,y,z)中z的大小。如果D>z,说明体素距离相机近。反之同理。 4、根据3中的结果更新体素中距离值D和权重W 其中 为当前帧立方体中该体素的权重, 为上一帧立方体中该体素的权重。
