We are a multidisciplinary team comprising software, hardware, signal processing and optoelectronics engineers tackling a problem with wide impact across multiple fields. PointCloud is used in the 3D panel.Schema. An option to do for now until the PointCloud class is wrapped up for C# is to obtain the camera intrinsics (for the depth camera if using the raw depth, or color camera if using depth aligned to color) and implement the Pinhole Camera Model (which is what the PointCloud class does internally). Pointclouds Surnia platform provides high-density point clouds as high as 640x480 points per frame, industry-leading sub-millimeter depth accuracy that is independent of distance to target, immunity against direct sunlight and extreme lighting conditions, and high dynamic range.
