Intel Realsens on Ubuntu 20.04
I just like to share my installation desription for my intel realsense d435 on ubuntu 20.04 with ros noetic. At the moment the realsense interface is without python bindings.

Thanks a ton! This really helped me!
Does this require to install an older kernel? Because the first apt-get throws an error:
@thodor I used a vanilla 20.04 that I downloaded on Oct 30; and I'm pretty sure the kernel was a 5.4.0, as that is the kernel for 20.04 (https://ubuntu.com/blog/ubuntu-kernel...) My current kernel is 5.4.0-56-generic, but it's possible that the patch revision was less than 56 at the time this procedure worked for me; however I think the kernel and the patch number might not be the issue. Hope it works out for you...
Note: To preserve compatibility by staying on a 5.4 kernel on 20.04 and not the newer 5.8 kernel (that by default you will get auto-upgraded to as of ~Jan 2021), you can hold some packages like described here: https://askubuntu.com/questions/93849...(No idea what's up with that failure with a 5.4.0-56 kernel though :/ )
Hello,
I'm using Intel RealSense D415/D435 cameras along with RealSense SDK2.0 (https://github.com/IntelRealSense/librealsense). There is a part at which I want to accelerate the speed, namely, /src/proc/align.cpp.
Before adding CUDA codes to align.cpp, I simply tried to compile the SDK after changing the file name from align.cpp to align.cu as well as from align.h to align.cuh. Following relevant information described here (https://github.com/jetsonhacks/buildLibrealsense2TX), I made changes at some parts of the SDK's CMakeLists.txt as follows:
----------------(SKIP)---------------------
option(USE_CUDA 'Use CUDA for GPU acceleration' ON)
if (USE_CUDA)
add_definitions(-DUSE_CUDA)
endif()
if (USE_CUDA)
find_package(CUDA REQUIRED)
include_directories({CUDA_INCLUDE_DIRS}) SET(ALL_CUDA_LIBS {CUDA_LIBRARIES} {CUDA_cusparse_LIBRARY} {CUDA_cublas_LIBRARY})
SET(LIBS {LIBS} {ALL_CUDA_LIBS})
message(STATUS 'CUDA_LIBRARIES: {CUDA_INCLUDE_DIRS} {ALL_CUDA_LIBS}')
set(CUDA_PROPAGATE_HOST_FLAGS ON)
set(CUDA_SEPARABLE_COMPILATION OFF)
list( APPEND CUDA_NVCC_FLAGS -03 -gencode arch=compute_61,code=sm_61 ) #For using GeForce GTX 1060
endif()
----------------(SKIP)---------------------
set(REALSENSE_CPP
---------(skip)----------
---------(skip)----------
)
set(REALSENSE_HPP
---------(skip)----------
---------(skip)----------
)
----------------(SKIP)---------------------
if (USE_CUDA)
set(REALSENSE_CUDA_CUH
src/proc/align.cuh
)
endif()
----------------(SKIP)---------------------

---------(skip)----------
Cmake Realsense Sdk
---------(skip)----------

source_group('Header FilesProcessing Blocks' FILES
---------(skip)----------
---------(skipt)----------
)
----------------(SKIP)---------------------
if (USE_CUDA)
link_directories(CUDA_LIBRARY_DIRS) target_link_libraries(realsense2 PRIVATE {LIBS})
endif()
----------------(SKIP)---------------------
CMake does not show any error. But when building libraries (e.g., realsense2.dll) on Visual Studio, I get some errors such as:
C2039 ‘HostingClass': 'global namespace' is not a member.
C2433 ‘librealsense:HostingClass': ‘friend' cannot be use to declare data.
In addition, I changed #include 'align.h' to #include 'align.cuh' in align.cu and rs.cpp – The latter two are the only parts that originally use align.h. Moreover, I checked 'CUDA 9.1(.targets .props)' under Build --> Customization. Furthermore, I selected 'CUDA C/C++' at the Property of align.cu and align.cuh each.

Could anyone give me some advice for solving the above issue?
