The purpose of this invention is to reduce the ambiguity in position caused by height differences in an object, and to estimate the position of an object with a high degree of accuracy. This object position estimation device comprises: a first processing unit which detects the position of a position reference point on a moving object from an image of the moving object obtained by a camera; a second processing unit for estimating the height of the moving object detected; a third processing unit for estimating the height of the position reference point on the basis of the estimated height estimated by the second processing unit and the image of the moving object; a fourth processing unit which calculates an estimated position candidate for the moving object on the basis of the height of the position reference point estimated by the third processing unit, the position of the position reference point, and the height of the point in the area; a fifth processing unit which calculates the likelihood of the estimated position candidate on the basis of the estimated position candidate calculated by the fourth processing unit, the height of the position reference point estimated by the third processing unit, and the height in the area; and a sixth processing unit which determines the estimated position of the moving object on the basis of the likelihood of the estimated position candidate calculated by the fifth processing unit.

The autonomous headlight height adjustment and masking system disclosed herein may comprise a system that automatically adjusts the level of the headlamps based on the elevation profile to be traversed so as not to blind other traffic by the controller of the high beams adjusting the headlamp to illuminate areas that do not interfere with other humans or vehicles based on the profile of the road or via another method in which there is a mechanism for masking or blocking the light emitted by the head light with a dynamic LCD or light segmented into different areas where they can be selectively turned on and off.

In a surveying instrument including an instrument height measuring unit configured to make a distance measurement by emitting distance-measuring light to a distance-measuring object below a vertical axis of a surveying instrument main body, and an arithmetic unit configured to calculate a distance to the distance-measuring object by analyzing light being the distance-measuring light that has returned by being reflected by the distance-measuring object, and calculate an instrument height, the instrument height measuring unit is configured to make a distance measurement by irradiating the distance-measuring light toward a predetermined region of the distance-measuring object centered on a point below the vertical axis of the surveying instrument main body, and the arithmetic unit is configured to calculate the instrument height by operating an average value of distance-measurement values in the region. By calculating an average value of results of distance measurements of a predetermined region, the measurement accuracy can be improved.

A surveying instrument capable of irradiating a spotlight as visible light for centering toward a position below a vertical axis of a surveying instrument main body is configured such that that an irradiation shape of the spotlight is a toric shape. When visible light for centering which passes through a center point of the surveying instrument and is projected on a position right below the surveying instrument is projected in a toric shape having a hole opened at a center like a donut shape, both of an inner circle and an outer circle can be recognized, so that many guides are provided, and it is easier for a worker to align the toric shape with the target point than a point shape, so that the burden of a centering work on the worker is reduced.
