Note that this method has been tested for the creation of white non-salient tags, therefore it is recommended that the user sticks to lighter colors.

POLARIS can be utilized with both visible and non-salient tags. In order to use POLARIS with non-salient tags, one must have completed the following prerequisites:

Connect a Near-Infrared (NIR) Camera to the System The camera must be capable of only viewing the NIR spectrum and must have an NIR emitter facing outward in the same direction that the camera is pointed attached to it. See the following tutorial for converting a visible PSEye to view NIR Conversion of the PS Eye Camera to NIR

Create Non-Salient Tags In order to create a non-salient tag, print an inverted AprilTag on a piece of paper with the color of the background that you wish to place the tag on. Put retro-reflective tape of the same color on the parts of the inverted tag that have black printed on them. Note that this method has been tested for the creation of white non-salient tags, therefore it is recommended that the user sticks to lighter colors. Here is an example of a finished non-salient tag for a white background:

Here is what the tag is interpreted as using the Infrared PSEye Camera:
