A surveying and mapping device for urban and rural planning

Abstract

The invention discloses a surveying and mapping device for urban and rural planning. The device includes: a position selection device, which is used to obtain the minimum distance between the laser range finder and the slope through the laser range finder rotating around the same vertical insertion rod. and the maximum distance, and determine the highest position point on the slope surface corresponding to the minimum distance and the lowest position point on the slope surface corresponding to the maximum distance; wherein, the insertion point of the vertical insertion rod on the slope surface is the selection center point; the surveying and mapping support device includes: Adjusting plate, the middle part of the bottom surface of the adjusting plate is equipped with a main inserting rod, and the bottom surface of the adjusting plate is also equipped with the highest position inserting rod and the lowest position lifting device. The lower end corresponds to the position of the lowest point on the slope. The invention controls the rising distance of the lowest position elevating device according to the difference between the minimum distance and the maximum distance, thereby realizing accurate leveling of the adjusting plate and further realizing accurate leveling of the surveying and mapping instrument.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, and more particularly to a surveying and mapping device for urban and rural planning. Background technique [0002] In urban and rural planning and construction, it is necessary to measure the land and draw relevant survey maps. Generally, the surveying and mapping instrument is fixed on the bracket, and the surveying and mapping instrument needs to be leveled before use, otherwise the accuracy of the measurement data will be affected. [0003] When carrying out land surveying and mapping operations on slopes, in order to ensure the level of the surveying and mapping instruments, the surveyors use the leveling brackets to achieve the leveling of the surveying and mapping instruments. There are usually two methods: First, excavate a plane on the slope land site to set up the brackets , because the plane of excavation is visually measured, and its flatness is not accurate, so the sur...
