Hi,

Has anyone tried to export the point cloud after processing data? there are some functions to export the trajectory but nothing for point cloud.

Hi, I followed your instructions on installing on Ubuntu 20.04 and experienced two consecutive errors in building opencv. I solved them with the following steps:

1. fatal error: stdlib.h: No such file or directory at #include_next <stdlib.h>. This is solved by adding -D ENABLE_PRECOMPILED_HEADERS=OFF to the "generating cmake config file" step in building opencv, as suggested here.
2. Cmake's build stopping abruptly after 99% having the same error in this post. This is solved by changing line char* str = PyString_AsString(obj); to const char* str = PyString_AsString(obj); in file opencv/modules/python/src2/cv2.cpp. This line can be located by typing /PyString_AsString in Vim Editor.
