This is an implementation of the Chamfer Distance as a module for pyTorch. It is written as a custom C++/CUDA extension. As it is using pyTorch'sJIT compilation, there are no additional prerequisite steps that have to be taken. Simply import the module as shown below; CUDA and C++ code ...

However, solely minimizing the chamfer distance between the predicted and the target mesh will lead to a non-smooth shape (verify this by settingw_chamfer=1.0and all other weights to0.0). We enforce smoothness by addingshaperegularizersto the objective. Namely, we add: mesh_edge_length, which...

pytorch——计算两个等大无序点云中的距离Earth Mover Distance 目前要做两个无序点集之间的相似性计算,在看过Chamfer Distance后,个人觉得CD的计算方式决定了其无法处理两个点集整体分布差异大,但是局部有部分点距离很近的情况,而这种情况在点集中是一定可能出现的,因此使用EMD可以保证每个点集都有一一对应的整体cost...

解决了，这是我代码中的一个错误：我调用model()的部分应该在with语句中，如下所示：
