kpconv-pytorch's Issues

数据处理的逻辑

  1. KPConv是网络一部分,网络初始化存储Kernel Points,而点云计算是直接;
  2. 特征点与坐标点一一对应,特征是可以任意组合的。
  3. 坐标点构成的KDTree用于查找半径空间内包含的坐标点。
  4. 训练时按照参数经过复杂的逻辑计算批量,保证训练的稳定性。
  5. 检测时(构成KDTree是现成的),自己定义数据结构有风险。(检测和训练是混合的,应该分开)3065行首先删除训练的,调试不相关的。
  6. 输出包含了 置信度,Potential,预测。可以统一打包发送出去。(一部分

KP的计算

点云输入KPConv模块后,怎么计算的?如果以点云的点为中心,那每个点计算的结果都是一样的,如果不是中心,那么各个点的计算关系是什么?

Redis点云的输入与输出

  • 现有代码的逻辑
  • Redis流:Python的XAdd和XRead
  • Python的PCD格式读写,pypcd
  • Python的内存文件模块(StringIO和BytesIO)
