摘要:

准确和快速响应的感知系统是自动驾驶汽车安全运行的基础。3D目标检测方法处理由LiDAR传感器给出的点云,以提供每次检测的准确深度和位置信息,以及其尺寸和分类。然后,该信息用于跟踪自动驾驶车辆周围的车辆和其他障碍物,并且还用于向控制单元馈送以确保避免碰撞和运动规划。现今,目标检测系统可分为两大类。第一种是基于几何的,它利用对3D点的几何和形态学操作来检索障碍物。秒是基于深度学习的,其处理3D点,或3D点云的细化,使用深度学习技术来检索一组障碍物。本文对这两种方法进行了比较,并在一辆真正的自动驾驶汽车上实现了每个类。估计的算法的准确性进行了评估与实验测试进行蒙扎ENI电路。本车和障碍物的位置由GPS传感器通过RTK校正给出,这保证了比较的准确地面实况。这两种算法都已在ROS上实现,并在消费者笔记本电脑上运行。

英文摘要:

An accurate and rapid-response perception system is fundamental for autonomous vehicles to operate safely. 3D object detection methods handle point clouds given by LiDAR sensors to provide accurate depth and position information for each detection, together with its dimensions and classification. The information is then used to track vehicles and other obstacles in the surroundings of the autonomous vehicle, and also to feed control units that guarantee collision avoidance and motion planning. Nowadays, object detection systems can be divided into two main categories. The first ones are the geometric based, which retrieve the obstacles using geometric and morphological operations on the 3D points. The seconds are the deep learning-based, which process the 3D points, or an elaboration of the 3D point-cloud, with deep learning techniques to retrieve a set of obstacles. This paper presents a comparison between those two approaches, presenting one implementation of each class on a real autonomous vehicle. Accuracy of the estimates of the algorithms has been evaluated with experimental tests carried in the Monza ENI circuit. The position of the ego vehicle and the obstacle is given by GPS sensors with RTK correction, which guarantees an accurate ground truth for the comparison. Both algorithms have been implemented on ROS and run on a consumer laptop.
