1. A method for vibration measurement for a sensor bracket, applied in a system for vibration measurement for the sensor bracket, the system comprising the sensor bracket that is mounted on a movable device, and a marker on the sensor bracket, and a sensor provided on the sensor bracket, wherein the marker has one or more sets of marks to be measured, each set of marks to be measured comprising two marks to be measured, with an initial position of a line connecting respective centers of the two marks to be measured being parallel to a plane on which the movable device is movable, wherein the marker has a plate-shaped structure with a front surface and a rear surface, and the front surface has the one or more sets of marks to be measured; the line connecting respective centers of the two marks to be measured is perpendicular to a direction in which the sensor bracket extends; the sensor is a first sensor mounted at an end of the sensor bracket; and a second sensor is mounted at another end of the sensor bracket, and the rear surface is fixedly connected to the second sensor, wherein the method comprises:
collecting marker information of the marker using the sensor;
determining a vibration measurement reference point based on the marker information; and
determining a vibration evaluation result for the sensor bracket based on a vibration condition of the vibration measurement reference point.
