Surveying and mapping method and device, computer equipment and storage medium

Abstract

The invention discloses a surveying and mapping method and device, computer equipment and a storage medium. The method comprises the following steps that: under preset frequency, through a multi-frequency GPS (Global Positioning System), obtaining the longitudes and latitudes of a plurality of sample points on a terminal movement locus; converting the longitudes and latitudes of the plurality of sample points into plane coordinates; according to the plane coordinates of the plurality of sample points, forming a closed appointed zone; and through a preset formula, calculating surveying and mapping data corresponding to the appointed zone. By use of the method, the built-in multi-frequency GPS of an intelligent terminal is used for realizing sub-meter level positioning, sample points with ahighest amount in the appointed zone are collected, the plurality of collected sample points are fit into a polygonal appointed zone, and therefore, the area and the perimeter of the polygonal appointed zone are calculated.

Description

technical field [0001] The invention relates to the technical field of digital measurement, in particular to a surveying and mapping method, device, computer equipment and storage medium. Background technique [0002] At present, most of the land area is measured by professional measuring instruments and manual measurement; using a measuring instrument to measure the area requires professionals to use it correctly, and at the same time, the measuring instrument is expensive and not suitable for people's daily use; and manual measurement requires manual throughput. Using a ruler to measure and manually calculate the area, manual measurement is time-consuming and laborious, and the accuracy is low. [0003] Therefore, in the prior art, the built-in GPS of the smart phone is used to measure the area, and the positioning error is more than 5 meters, which cannot be used for high-precision area measurement, so the accuracy is low and the user experience is not good.

[0002] At present, most of the land area is measured by professional measuring instruments and manual measurement; using a measuring instrument to measure the area requires professionals to use it correctly, and at the same time, the measuring instrument is expensive and not suitable for people's daily use; and manual measurement requires manual throughput. Use a ruler to measure and manually calculate the area, manual measurement is time-consuming and laborious, and the accuracy is low

[0003] Therefore, in the existing technology, the built-in GPS of the smart phone is used to measure the area, and the positioning error is more than 5 meters, which cannot be used for high-precision area measurement, so the accuracy is low and the user experience is not good.
