Landscaping accurate modeling construction method based on RTK technology

Abstract

The invention discloses a landscaping accurate modeling construction method based on an RTK technology. The method comprises the following steps of collecting a hand-painted or real-sight pattern; extracting the contour shape of a collected image and storing as the contour image of a CAD format; using the RTK technology to measure a topographic map and forming a CAD base map with a geodetic coordinate; opening the CAD base map, copying the contour image with a base point to the CAD base map and moving to a position where landscaping modeling construction is required, and then, acquiring the geodetic coordinates of each inflection point and / or the arc connection point, and the vertex of the contour image; through an RTK mapping technology, carrying out point release measurement and point release marking on the geodetic coordinate of each point of the contour image; and connecting the points in the point release marking in the field according to a graphic structure to form a graphic contour. Through a landscaping technology, according to a design requirement, the graphic contour is filled so as to acquire the landscape modeling of a hand-painted graph. The method possesses advantagesthat modeling precision is high; an aesthetic feeling is achieved; a man-made influence factor is small; and a construction process is simple and high-efficient.

Description

technical field [0001] The invention belongs to the technical field of landscaping, and in particular relates to an accurate modeling method for landscaping based on RTK technology with high modeling precision, strong artistic sense, small human factors and simple and efficient construction process. Background technique [0002] Landscaping is the use of engineering technology and artistic means in a certain area to bring out the spiritual culture of human subjects by transforming the terrain (or further building mountains, stacking stones, and water management), planting trees and flowers, building buildings, and arranging garden roads. The beautiful natural environment and recreational environment. [0003] The modern lifestyle and living environment have urgent functional and artistic requirements for gardens. Therefore, in landscaping, words and patterns are often used to express the spiritual outlook of a city or enterprise. In the prior art, there are mainly two metho...

Problems solved by technology

In the prior art, there are mainly two methods for the construction of text or pattern modeling in landscaping: one is that artists and staff directly draw pictures or pull threads in the field, or use a method similar to cross-stitching to outline the graphic outline, and then Fill it with trees, flowers, buildings, and paths to obtain the required shape; although the cost of the constructed shape is low, there are generally shapes that are only suitable for simple graphics, and the constructed shape is dull, the artistic sense is not strong, and the personnel Subjective influence is more serious

The second is to use GPS position fixed-point mapping; however, since the GPS civilian positioning accuracy can only reach the meter level, it is often difficult to construct artistic cursive scripts, fonts with outstanding personal characteristics, and graphics with complex configurations. details, the shape after construction also has the problems of rigidity, lack of details, and weak artistic sense; in addition, due to the irregular structure of artistic graphics or fonts, it is difficult to accurately correspond to the GPS position after zooming in, which will also cause problems after construction. The shape is distorted, affecting its artistic expression

Generally speaking, calligraphers' fonts are elegant and smooth, and their strokes are full of twists and turns, while celebrities' inscriptions have prominent personal characteristics; It is still relatively difficult to shape inscriptions, paintings, and real scenes
