Indoor whole-house dynamic scanning
L2 can quickly and accurately obtain the 3D structural information of the entire house, which facilitates the positioning and autonomous navigation of mobile robots. It can also help robots expand more diverse functions such as whole-house cleaning and organization.
Outdoor real-scene dynamic scanning
L2 can effectively resist the interference of indoor ambient light and outdoor strong light. Under strong light conditions of 100Klux outdoors, it can achieve stable ranging and high-precision mapping.
Non-repetitive scanning
L2 achieves high-precision and high-density point cloud data through omnidirectional ultra-wide-angle non-repetitive scanning, realizing photograph-level scanning effects.
