Description

Land mapping calibration device convenient to operate Technical Field The invention relates to the technical field of land mapping calibration, in particular to a land mapping calibration device convenient to operate. Background With rapid development of mapping technology, global Navigation Satellite System (GNSS) receivers and total stations have been widely used in the fields of topography measurement, cadastral investigation, engineering lofting, and the like. In practice, an operator is often required to take a single hiking measurement with a hand-held prism rod or a carbon fiber centering rod (RTK rod). The centering rod usually adopts a telescopic structure, the operation height can reach 2 to 3 meters, and in order to ensure portability, carbon fiber materials are adopted. The mechanical structure of the centering rod determines a high center of gravity of the top due to the large slenderness ratio (length to diameter ratio) of the centering rod. When the device meets uneven terrains such as mountain lands and ditches or works in areas with soft soil and dense vegetation, an operator holds the middle of the rod body by one hand, so that an unstable lever effect is very easy to form. The external weak ambient wind force or physiological micro-shake (hand shake) of the human body can cause obvious displacement at the top end of the rod body after being amplified by a longer force arm, so that the round level bubble on the centering rod is difficult to quickly and stably maintain at the center position. The method prolongs the acquisition time of a single measuring point, more directly leads to the increase of centering errors and seriously influences the accuracy of measured data. In engineering lofting or topography fragment measurement, the operation often has the characteristics of long duration and dense point location distribution. The operator needs to keep the arm in a suspended state for a long time to straighten the centering rod, and the static muscle force application mode is extremely easy to cause ache and fatigue of arm and shoulder and back muscle groups. Particularly, in high-strength operation of frequently replacing measuring points, along with the decline of physical ability, the ability of an operator to control the perpendicularity of the rod body can be further attenuated, and vicious circle of fatigue-precision decline is formed, so that the overall efficiency of field mapping operation is greatly reduced.
