 In this custom configuration, the **use_voxel_center_z parameter** is set to **False** to deactivate the z coordinate of the voxel center,
 aligning with the original paper's specifications and making the model compatible with Autoware. Additionally, the filter size is set as **[32, 32]**.

 The lidar_centerpoint implementation requires two ONNX models as input the voxel encoder and the backbone-neck-head of the CenterPoint model, other aspects of the network,
 such as preprocessing operations, are implemented externally. Under the fork of the mmdetection3d repository,
 we have included a script that converts the CenterPoint model to Autoware compatible ONNX format.
