WebApr 15, 2024 · Expand. These early simulation tests aim to simulate a Velodyne Puck™ sensor, using Unity’s Sensor SDK and the System Graph, which is so precisely calibrated that it becomes almost indistinguishable from actual lidar data. To test this, we lidar-scanned a real-world location with a Velodyne Puck™, and brought the lidar data into Unity. WebTo calculate reflectivity, the lidar sensor uses the Phong reflection model. This model describes surface reflectivity as a combination of diffuse reflections (scattered … WebLidar data is a three-dimensional point cloud that provides a highly accurate and highly precise means of measuring a surface or an object. These point clouds contain a wealth of data, but for that reason they can be overwhelming to visually interpret and exploit. edsc meaning
