To accurately obtain the shapes of a hoisting load and an object located near the hoisting load, and the height of the ground surface, and present an accurate warning display when the hoisting load approaches the object. A guide information display device is equipped with a data processing unit which: estimates the top surface of a hoisting load, the ground surface, and the top surface of the object, on the basis of a data point group obtained by a laser scanner; generates guide frames representing guide frames that surround the top surface of the hoisting load and the top surface of the object, and also generates height information and height information which represent the elevation of the hoisting load and the object; calculates the distance between the hoisting load and the object on the basis of the estimated top surfaces of the hoisting load and object; and outputs a warning display when the distance is equal to or less than a threshold. The guide information display device is also equipped with a data display unit for displaying guide information obtained by overlapping an image captured by a camera with the guide frames, the height information and the height information, and the warning display which were generated by the data processing unit.

A position measurement method is used by a device including an imaging unit and a position detector that detects a position of the imaging unit to measure, using a detection value at imaging of a measurement point, position coordinates of the measurement point. The method for correcting the detection value from the position detector includes obtaining, with the device, position coordinates of predetermined indices (22) arranged two-dimensionally on a calibration plate (20) as an actual measurement value, obtaining, as a correction value, a difference between the actual measurement value and a true value resulting from transformation of position coordinates of the indices (22) with respect to a reference point on the calibration plate (20), and correcting the detection value from the position detector (8, 9, 10). The imaging unit (3) images measurement points (P) on the measurement target (3) to measure position coordinates of the measurement points (P).

A method for determining a trailer detection parameter of a trailer including receiving an image from at least one camera at a controller. The at least one camera defines a field of view including at least a portion of a vehicle trailer. The method determines a trailer angle of the vehicle trailer relative to a tractor, identifies at least one feature in an image of the trailer, determines a two-dimensional distance from the at least one feature to a predefined position on the image, and converts the two-dimensional distance to a three-dimensional distance based at least in part on the determined angle. The three-dimensional distance is a trailer detection parameter of the trailer.
