Space positioning method based on digital codes

Abstract

The invention discloses a space positioning method based on digital codes. The method comprises the following steps of: using a Cartesian rectangular coordinate system; selecting a preset position as a coordinate origin; building a coordinate system; obtaining a coordinate position of a target point; generating an initial digital code according to a preset coding rule, wherein the digital code comprises an administrative region code, an area code, an address code and a height code; obtaining an error correction coefficient of the target point from the origin in directions along the transverse and longitudinal coordinates through comparing the longitude and latitude addresses of the target point and the origin; using an error correction algorithm to obtain the corrected area code and address code of the target point through calculation; further obtaining the final digital code of the target point. The method has the beneficial effects that the target points can be precisely positioned and uniquely expressed; and precise positioning information can be continuously and stably obtained.

Description

technical field [0001] The present invention relates to the technical field of spatial positioning, in particular to a digital coding-based spatial positioning method. Background technique [0002] With the rapid development of transportation and network urbanization, the scope of people's activities is expanding day by day, and the demand for geographical and spatial positioning is becoming stronger and stronger. Latitude and longitude positioning is the most accurate positioning method at present. Every point on the earth has its unique latitude and longitude coordinates. However, the calculation and positioning of latitude and longitude are too professional and complicated for ordinary people, and the latitude and longitude coordinates lack the description of the geographical, location and social attributes of the point. Therefore, the positioning method directly using latitude and longitude coordinates is not widely used, and is mostly used in professional fields such...

However, because it is only used within the postal range, the information contained in the digits is too single, and the range of the positioning area is too large. It often needs to cooperate with detailed address information to achieve accurate positioning. The positioning is not accurate and the scope of use is limited.
