lidar – SyntaxBug

Manually drive in CARLA, add stereo camera, lidar Lidar

CARLA usage logic: Create the client first Set to terminate if nothing is returned from the server for 2 seconds client = carla.Client(“127.0.0.1”, 2000) client.set_timeout(2.0) Get world from the client world = client.get_world() Set settings and apply Here we use asynchronous mode with a fixed time step settings = world.get_settings() settings.synchronous_mode = False # Enables […]

Gazebo simulates lidar for distance and intensity data collection range+intensity, reflector navigation

Setting a high value for some objects makes it possible to simulate a 2D lidar scanner to output high-intensity data containing the angles at which reflectors exist. Will this work? I want to simulate lidar in gazebo and record rosbag, but the online tutorials basically set and record the range, and cannot collect the reflection […]

Direct lidar odometry: rapid positioning based on dense point clouds

Summary This article proposes a lightweight front-end lidar odometry solution for fast and accurate positioning capabilities on robot platforms with limited computing power. Our direct lidar odometry prioritizes computational efficiency and provides accurate pose estimates in real time using dense, minimally preprocessed point clouds, an approach that can efficiently manage historical map information. Additionally, a […]

3D point cloud data set production record [LiDAR]

I’ve been working with robots for the past two years. Earlier this year, instead of just focusing on cameras, I decided to start using lidar. So, after a lot of research, I settled on the 32-bundle RoboSense device. Recommended: Use NSDT editor to quickly build programmable 3D scenes I had to spend some time setting […]
