youyeetoo L1 4D 3D LiDAR Scanner, 360 Degree, 30 Meters Scanning Radius, ROS SLAM LIDAR Sensor, for AGV Robot Navigation and Obstacle Avoidance (L1PM (20M))
[3D position + 1D grayscale] L1RM 4D-LiDAR is a 4D lidar rangefinder module, which can be widely used in robots, smart cities, smart toys, logistics and other fields, supporting mapping, positioning, identification, avoidance Implementation of functions such as obstacle, environment scanning, and 3D reconstruction.
[Hight Performance] L1RM 4D lidar has built-in 3-axis acceleration and 3-axis gyroscope IMU modules, supporting a push frequency of 250Hz. The circumferential scanning frequency of L1 is 11Hz, the vertical scanning frequency is 180Hz, and the effective sampling frequency is 21600 points/ Second. L1 not only has excellent performance, but also has high reliability. It can also achieve stable ranging and high-precision mapping under the strong light of 100K lux outdoors.
[360°+90°] L1RM lidar sensor scanner has excellent ultra-wide-angle scanning capabilities. The field of view (FOV) extends to 360° horizontally and 90° vertically. It can realize three-dimensional space detection with a hemispherical field of view, and its application range can be expanded to More commercial scenarios.
[Whole House Dynamic Scanning] L1RM 4D 3D lidar scanner can quickly and accurately obtain the three-dimensional structural information of the whole house, which facilitates the positioning and autonomous navigation of mobile robots, and can help the robot expand richer functions such as whole-house cleaning and organization.
[Low Blind Zone] L1RM 4D lidar sensor has an ultra-low blind zone and a minimum detection distance of 0.05m, making it easy to achieve close range detection and recognition. It also supports non-repetitive static scanning. Through omnidirectional ultra-wide-angle non-repetitive scanning, high-precision point cloud data can be obtained to achieve image-level scanning effects.
