The SPiDER Scanner is the first wireless and color point cloud manhole inspection technology in the world. It is lightweight and compact and can produce 3D video, 3D images, and measurable 3D meshes with 5 mm accuracy. The MACP SPiDER point cloud is the only technology that calculates the manhole volume to assess wall thickness variation before and after rehabilitation. CUES SPiDER is revolutionizing manhole inspections and case studies will be presented.
