CHCNAV RS7 is a high-performance portable 3D LiDAR SLAM scanner designed for construction, indoor surveying, and 3D mapping applications.
By combining high-precision INS and SLAM, a high-accuracy IMU, and a LiDAR scanner capable of capturing up to 1.15 million points/s, the RS7 enables fast and accurate 3D data acquisition. Its ultra-wide 360° × 189° field of view, dual HD cameras, and support for 3D Gaussian Splatting enable detailed and realistic 3D models.
