Abstract
A camera captures an image of a structural bearing, such as a hanger bearing or a rocker bearing. Additionally, an instrument detects a temperature. A computing system determines, based on the temperature, an expected angle of the bearing relative to a base line. The computing system also determines an actual angle of the bearing relative to the base line. The computing system superimposes a first line on the image, the first line indicating the expected angle. Furthermore, the computing system superimposes a second line on the image, the second line indicating the actual angle.
