A review of visual SLAM methods for autonomous driving vehicles 2.2 Front end The front end for visual SLAM is known as Visual Odometry (VO). It is responsible for estimating the camera motion and feature orientation roughly based on the information of adjacent frames. In order to obtain the ...
GPS, LASER odometry and most recently Visual Odometry (VO) [88] and Simultaneous Localization and Mapping (SLAM) [36,38] methods have been proposed. VO is the process of estimating the egomotion of an agent (e.g., vehicle, human, and robot) using only the input of a...
提出OVD-SLAM系统:文章提出了一个名为OVD-SLAM的系统,该系统能在动态环境中进行鲁棒且实时的视觉同时定位与地图构建(SLAM)。这是一个显著的贡献,因为动态环境中的SLAM一直是一个具有挑战性的领域。 无预定义动态标签的动态点识别:通过结合YOLOv5、光流和深度信息,OVD-SLAM系统能够确定包含动态对象的边界框,而无需预...
此类基于视觉的动态SLAM方法具有广泛应用前景，适用于自动驾驶、AR/VR与无人机等领域。OVD-SLAM系统框架：首先，RGB图像通过目标检测网络处理，深度图像被分成分区前景与背景。利用光流与前景分割结果，确定动态对象的区域。在定位与地图构建的第一阶段，利用动态区域先验信息去除前景点，初始化相机姿态。第二...
The integration of AI across industries has recently become mainstream, in most fields except space technology. This overview follows Heintz (Heintz, 2022). A key reason that aerospace lags is simply the high stakes: some missions are too big to fail; some represent national prestige; still othe...
Visual SLAM的目标是使用移动代理上的传感器构建环境地图,并实时计算该地图中代理的姿态。相比之下,VO系统将重点放在计算代理的自我运动上,而不是构建地图。SLAM图的最大优点是,它允许在BA中匹配和使用先前的观察结果,执行三种类型的数据关联(扩展[1]中使用的术语):...

and Graph-SLAM rely on 2D or 3D point cloud collected by LiDAR and/or IMU measurements to simultaneously locate a robot and create a map to represent the physical environment (e.g., bridge inspection site). RGB-SLAM2 is a specific type of Visual-SLAM system that can handle imagery data ...
The method is part of a complete system for automatic map building and Simultaneous Location and Mapping (SLAM). The method uses optical flow to determine whether the robot has undergone a movement. If so, some visual features that do not satisfy several criteria are deleted, and then ego...
