1. A system for guiding total station relock, the system comprising:
a surveying instrument;
a base station positioned in an environment;
an augmented-reality device comprising a camera; and
one or more memory device containing instructions that, when executed, cause one or more processors to perform the following steps:
calculating a position of the surveying instrument in relation to the augmented-reality device, while an object in the environment blocks line of sight from the base station to the surveying instrument;
calculating a position of the surveying instrument in relation to the environment based on the position of the surveying instrument in relation to the augmented-reality device; and
transmitting the position of the surveying instrument in relation to the environment to the base station.
