Textured retro-reflective marker

An apparatus comprising:

• a retro-reflective marker, comprising:
• a retro-reflective layer having a first retro-reflectance capability, the retro-reflective layer comprising:
• a textured surface, a portion of the textured surface having a surface topology such that surface normal vectors of the portion of the textured surface extend from the portion of the textured surface in different directions, and
• a plurality of retro-reflective micro elements distributed across the textured surface;
• and
• a border defining a retro-reflective area of the retro-reflective layer, wherein a portion of the border provides a second retro-reflectance capability lower than the first retro-reflectance capability;
• and
• a base comprising at least one feature configured to guide the retro-reflective layer when the retro-reflective layer is placed on a top surface of the base such that the retro-reflective area aligns with a pre-determined location of the base.
