kitti 数据集groundtruth如何获取

KITTI数据集的groundtruth是通过人工标注获得的。在KITTI数据集中，每个样本都包含了多个传感器采集的数据，如图像、激光雷达点云等。这些数据通过标注工具进行处理，人工标注出每个样本中的目标物体（如车辆、行人等）的边界框和类别信息。标注人员会根据每个样本的传感器数据，结合自身的经验和标注规则，对目标物体进行准确的标注。因此，KITTI数据集的groundtruth是经过精细标注的，可以用于训练和评估自动驾驶算法的性能。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
