Default Black on white disks dotting the ISS ?


What are they?

Some are flat, others raised and sometimes angled.

Thanks

"In order to line up this new piece of truss with the one already
installed on the laboratory, we used a system called the space vision
system (SVS) in addition to the camera views. This system determines the
distance between strategically placed black dots on the previously
installed structure relative to the piece of structure that is being
installed. "

The Shuttle's Canadian-built mechanical arm has been enhanced with a new
"Space Vision System" (SVS) that will help the operator literally see
around corners. Tested on past Space Shuttle missions STS-74, STS-80 and
STS-85, the SVS uses video image processing and a series of markings on
the objects being maneuvered to develop a graphical laptop computer
display to assist the arm operator. It allows the Shuttle arm to
be operated with great precision even when visibility is obstructed, and
the system was used operationally for the first time during the first
assembly mission as astronaut Nancy Currie, with her view partially
obstructed, attached the first station component, the Zarya control
module, to the second component, the Unity connecting module.
