Detailed Description

KITTI点云数据集类/KITTI point cloud dataset class.

用于加载和访问指定目录下的KITTI格式点云数据/Used to load and access KITTI format point cloud data in a given directory

// 示例：加载KITTI点云数据集并访问点云
toolbox::io::kitti_pcd_dataset_t dataset("/path/to/velodyne");
std::size_t n = dataset.size(); // 获取点云数量/Get number of point clouds
auto cloud_opt = dataset.at(0); // 访问第一个点云/Access the first point
cloud if (cloud_opt && *cloud_opt) {
  // 使用点云/Use the point cloud
}
