Multi-attitude all-terrain geographic information surveying and mapping instrument

Abstract

The invention belongs to the field of geographic surveying and mapping, and particularly relates to a multi-attitude all-terrain geographic information surveying and mapping instrument, which comprises a base, a tripod and a surveying and mapping instrument body, the lower surface of the surveying and mapping instrument body is fixedly connected with a mounting seat, the lower surface of the mounting seat is provided with ball grooves which are uniformly distributed in a circular ring shape, and the upper surface of the base is rotatably connected with an adjusting seat; a fixing groove is formed in the center of the upper surface of the adjusting seat, a rotating disc is movably installed in the fixing groove, magnetic beads in one-to-one correspondence with the ball grooves are fixedly installed on the upper surface of the rotating disc, a rotating shaft is welded to the lower surface of the rotating disc, a turbine rod is rotationally connected into the adjusting seat, and a movable groove flush with the upper surface of the adjusting seat is formed in the adjusting seat. A screw rod is installed inside the movable groove, the top of the screw rod is fixedly connected with an adjustment frame, and a column gear is installed in the inner part of the adjustment seat. According to the surveying and mapping instrument, the structure is simple, the micro adjustment of the surveying and mapping instrument can be assisted, the adjustment time of the surveying and mapping instrument is shortened, and meanwhile the accuracy of measured data is improved.

Description

technical field [0001] The invention belongs to the field of geographical surveying and mapping, in particular to a multi-position and all-terrain geographic information surveying and mapping instrument. Background technique [0002] Surveying and mapping refers to the measurement, collection and drawing of the shape, size, spatial position and attributes of natural geographical elements or surface artificial facilities, etc.; measuring instruments are mainly used for measuring instruments on construction sites, and benchmarks and horizontal planes are required for measurement The measurement accuracy can only be guaranteed vertically. When entering the geographic surveying and mapping operation, first perform horizontal calibration, and then carry out the geographic surveying and mapping operation. When performing the operation, a micro-adjustment is required to ensure that the data is within a measurement range, but when performing a micro-adjustment Excessive adjustment o...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology and solve the problems of reduced data accuracy and long adjustment time due to the excessive adjustment error of each azimuth of the surveying instrument during the micro-adjustment of the approach, the present invention proposes a multi-attitude all-terrain Geographic Information Mapping Instrument
