Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features of the embodiments of the present invention may be combined with each other.
The following detailed description is exemplary in nature and is intended to provide further details of the invention. Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention.
At present, a common method for correcting the RTK centering rod circular level mainly refers to a correction method of a prism centering rod, and a total station is used for correction, but because the prism centering rod generally has a two-foot support matched with the prism centering rod, the prism centering rod is stable after being erected, the calibration work can be relatively simply completed, but the RTK centering rod does not need two feet matched with the prism centering rod in the use process, so that the two-foot support matched with the prism centering rod is not arranged, the RTK centering rod cannot be stably erected in the calibration process, and the total station is relatively difficult to calibrate. A typical method commonly used is shown in fig. 7:
the method comprises the steps of installing a prism on a centering rod, enabling the lower tip of the centering rod to stand on a point O, utilizing a tripod to assist or supporting the centering rod with a stick to hold the centering rod by hands, enabling a circular level to be centered, then respectively erecting a total station on the point A and the point B, centering and leveling an instrument, enabling a cross wire of the total station to aim at the tip of the centering rod, keeping the horizontal direction unchanged, rotating a vertical adjusting screw to a prism head, observing whether the center of the prism coincides with the left and right directions of the cross wire of the total station or not, and if not, indicating that the circular level of the centering rod needs to be corrected.
The adjusting steps are as follows:
(1) as shown in fig. 7, the total station is erected at point a, the aiming prism tip is up to the prism head, if the cross of the total station is not coincident with the cross of the prism, the prism head is tilted in the left and right directions facing the total station to make the center of the prism coincide with the cross of the instrument, at this time, the bubble of the centering rod is not centered, the adjusting screw at the bottom of the circular level is adjusted to center the bubble, and then the instrument is observed to see whether the center of the prism coincides with the cross of the instrument. Repeating the steps until the air bubble of the centering rod circular level is centered.
(2) The centering rod is fixed, the prism is rotated by 90 degrees, and the inspection and adjustment are carried out by using a total station at the point B. Until the prism center coincides with the instrument cross. At this time, the centering rod circular level is corrected. If more accuracy is required, the above steps need to be repeated at A, B for two points.
Other common centering rod calibration methods also need to use a total station and a tripod, at least two persons are matched, and the instrument needs to be repeatedly erected back and forth in two directions, so that the operation process is complicated and time is consumed. In addition, the metal tips of the common tripods are very sharp, so that the common tripods can only be operated outdoors in order to avoid damaging the floor or damaging instruments when the tripods are toppled in the operation process. Other correction methods such as a suspension method and the like for the RTK centering rod without using a total station, a tripod and the like have high operation difficulty and cannot easily ensure correction precision.
