Make Planes

AVOD needs the planes file to provide ground plane information, but the official planes generation tool has not yet been provided, which brings great difficulty to the test work. This project is used to generate planes files especially for AVOD testing.

Functions

Generate the planes files for the KITTI testing data or your own data

• lidar4to3(input_file_path, output_file_path): Convert the KITTI lidar points from Nx4 shape to Nx3 shape.

• cal_planes(input_file_path="./points/", output_file_path="./planes/"): Using Ransac in PyntCloud to find the groud plane.

• lidar_point_to_img_calib(point, Tr, R0, P2): Convert lidar points to the camera.

• calib_at(file_path, file_index): Return the calib sequence.

• load_kitti_calib(file_path, file_index): Load projection matrix.

Input

• calib
• velodyne(Nx4)

Output

• points(Nx3)
• planes

Getting Started

• The project is based on PyntCloud. You need to install it first.

  git clone https://github.com/daavoo/pyntcloud.git

  pip install -e pyntcloud

  It seems like the PyntCLoud is updated. This code may not work for the new version. So I Upload The Old Version In This Repo.

• Set the path of your dataset in main.py.

  You can also set the specified output path for the generated Points(Nx3) files and the Planes files. Note that the input path of cal_planes() needs to be consistent with the output path of lidar4to3(). The default output path for the Points file is './points/', and the default output path for the Planes file is './planes/'.

• Run the main.py to start generating.

  python main.py

• For the KITTI dataset, the error data self-checking function is included in the cal_planes() function. Plane data with a height less than 1.3 meters or greater than 2.0 meters is determined as erroneous data and replaced with default data (0, -1, 0, 1.65). The decision criteria and default values can be modified in the cal_planes() function. For erroneous data, its name and origin plane data will be stored in the error.log file.

  Due to the principle of the generation of planes, there may be subtle differences in the generated planes data each time.
