Hi, For 3D detection, distance is calculated by depth and intrinsic parameters of cameras. I noticed that in nuScenes dataset, all 6 cameras have different intrinsic parameters. Since you are...

怎么把光流结果加入Tracking过程呀

您好，十分感谢您能开源代码。我有个疑问想问下，您的代码是在Track前面进行一次光流计算对嘛，但是我不太理解光流计算的结果会怎样影响SLAM的结果呢？我看到光流算出来的RT仅仅是命令行输出了一下，并没有赋值之类的。您CSDN上面说的“使用光流法跟踪非关键帧，不需要提取所有帧的特征点。”是需要在哪里修改代码呀？

Hi, thanks for sharing your work. Do you have any plans to release the code for the velocity supervision part?
