VirtualGrid has announced the availability of VRMesh v9.5, the latest version of its 3D point cloud and mesh processing software. The new release provides a simple and fast way for LiDAR strip adjustment with high accuracy. It adds a new feature to separate overlapping LiDAR strips, redesigns and speeds up global registration by 10 times. It also allows geospatial professionals to generate a PDF report for viewing the quality of registration.
The complete workflow of strip adjustment includes:
Step 1: Separate overlapping LiDAR strips based on the selected trajectories.
Step 2: (Optional) Automatically classify vegetation in each strip to get a clean surface.
Step 3: Run global registration to fix the misalignment between the laser scanner and the inertial measurement unit (IMU).
The classification features in VRMesh are designed to easily identify noisy objects on the surface, e.g. vegetation, in each LiDAR strip to prevent the noises from disturbing strip adjustment. The global registration method works well for unstructured point clouds. VRMesh says the software provides a flexible and accurate strip adjustment solution for both airborne and mobile LiDAR data.
