Steps (see their readme also)

• install CUDA toolkit https://developer.nvidia.com/cuda-downloads?target_os=Windows&target_arch=x86_64&target_version=10&target_type=exe_local
  • you can remove all the extras, like geforce experience and docs etc *i installed 11.4
• install cmake https://cmake.org/download/ (latest release, not RC), i took 3.22.5 *3.23 doesnt work?
• install optional (for DLSS) https://vulkan.lunarg.com/sdk/home#windows (base sdk only)
• make folder somewhere, lets say E:\apps\NeRF\

The background is that the default OpenWRT image for Raspberry Pi lacks drivers for the LAN port (RTL8111) on the DFRobot board. DFRobot provide an image, but that one is made from a quite old daily snapshot of OpenWRT which is not entirely stable. Also, it is better to know how to fish than be given a fish.

DFRobot's page about the router board:
https://wiki.dfrobot.com/Compute_Module_4_IoT_Router_Board_Mini_SKU_DFR0767

OpenWRT main page:
https://openwrt.org/

You are expected to have some general knowledge on Linux and OpenWRT. The instructions for flashing the resulting firmware image are presented on DFRobot's page.

def get_inverse_pespective(perspective_matrix: np.array)-> np.array:
  """
  This method calculates the inverse of prespective matrix by homography. 
  - Takes 4 random points on the floor plane(destination_plane) and calculates the corresponding points 
  on the camera image plane(src_plane) using perspective matrix.
  - Calculates the Homography matrix to map any point in image plane to floor plane.
