Abstract: Disclosed are various embodiments for a surveying and navigation system that includes reflectors designed to both (1) facilitate surveying of a facility area using a three-dimensional (3D) light detection and ranging (LiDAR) scanner and (2) enable guidance of an automated guided vehicle (AGV) within the facility area. The reflectors are designed to include at least one surface section that is free of a highly reflective surface (e.g., retro-reflective) that is used to guide the AGVs within a facility. When a reflector is scanned by the surveying during a surveying phase, the surface section of the reflector surface that is free of the reflective surface scatters the light associated with the scan. The corresponding scattered data can be used to discern the shape of the reflector thereby enabling an accurate determination of the reflector location coordinates for surveying.
