This code provides an API to voxelize input point clouds and outputs the occupied information of each voxel.

- CUDA
YOU need to first ensure you have added environment settings in your ~/.bashrc:
export PATH="/usr/local/cuda/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/cuda/lib64:$LD_LIBRARY_PATH"
To inplace install:
$ python setup.py build_ext --inplace
or install
$ python setup.py install
to test:
$ python test.py
- An example:
#### Settings
num_points = 4096
size = num_points
outsize = 2048
num_y = 120
num_x = 40
num_height = 20
max_height = 1 # max height
max_length = 1 # max_length in xy direction (same for x and y)
#### Usage for voxelization
test_data = test_data.transpose()
test_data = test_data.flatten()
voxelizer = voxelocc.GPUTransformer(test_data, size, max_length, max_height, num_x, num_y, num_height, outsize)
voxelizer.transform()
point_t = voxelizer.retreive()
point_t = point_t.reshape(-1,3)
