DISTANCE MEASUREMENT SYSTEMS AND METHODS

A system including a laser reading unit and a laser distance measuring unit is disclosed. The laser reading unit may be mounted on a device body associated with a device. The laser reading unit may read a laser signal projected by a laser projecting unit to establish a reference point. The reference point is a point at which the laser reading unit reads the laser signal projected by the laser projecting unit. The laser distance measuring unit may also be mounted on the device body. The laser distance measuring unit may measure a vertical distance between the reference point and ground.
