    摘要: A method comprises detecting at a plurality of light-receiver units, an impingement position of the light plane on a photo sensor that has a known relative position in relation to the surface, determining, for each light-receiver unit and based on the impingement position and the known relative position, a crossing position value of the light plane with respect to the surface, performing a combined analysis of the crossing position values from the plurality of light-receiver units to derive alignment information comprising the deviation of the alignment of the surface of the structure relative to the light plane, and displaying the alignment information to a user. The invention also relates to computer programme product, a light-receiver unit and a system comprising a plurality of light-receiver units for performing the method.

    摘要: A locating and marking device. The device has one or more antennas capable of detecting a signal emanating from an underground line. A marking device, such as a paint canister, is located on the frame of the device. This marking device leaves a physical or virtual mark at an above-ground path overlying the underground line. A processor receives signals from the antennas and directs the device to place the marking device above the above-ground path. The marking device may move back and forth on a frame of the device, or the device may steer to maintain the marking device in the proper position.
