1. A method for inspecting an expansion joint, the method comprising:

  • receiving, by a computing system, an image captured by a camera, the image being of a structural bearing, wherein the structural bearing is a hanger bearing or a rocker bearing;

    receiving, by the computing system, a temperature measurement generated by an instrument;

    determining, by the computing system, based on the temperature, an expected angle of the structural bearing relative to a base line;

    determining, by the computing system, an actual angle of the structural bearing relative to the base line;

    superimposing, by the computing system, a first line on the image, the first line indicating the expected angle; and

    superimposing, by the computing system, a second line on the image, the second line indicating the actual angle.
