What does this application do?

This application demonstrates the Perspective Warp function of NVIDIA VPI with OpenCV ArUco module.

Prerequisites

• NVIDIA Jetson Series Developer Kits
• NVIDIA JetPack 4.5 or later
• USB Camera

Installation

1. Install OpenCV which includes the ArUco module. The pre-installed OpenCV of JetPack does not include the ArUco module. The install_opencv4.5.0_Jetson.sh script can be used to build OpenCV with ArUco module in addtion to the GPU support. The build takes 2~3 hours on Jetson.
2. Download this repository.

   $ git clone https://github.com/MACNICA-CLAVIS-NV/vpi_perspective_warp_aruco
   

3. Build the application.

   $ cd vpi_perspective_warp_aruco
   $ mkdir build
   $ cd build
   $ cmake ..
   $ make
   

Execution

1. Print the marker sheet.
2. Excute the application and place the marker sheet in front of the camera.

$ ./vpi_perspective_warp_aruco --video video_file_to_be_warped
