Abstract

The invention discloses a spatial digital plotting and 3D visualization method for a private garden. The method comprises the following steps that S1) data collection is carried out by obtaining holographic data of a plotting research object as well as holographic data of a control target via a 3D laser scanner, and close-range multi-visual-angle shooting measurement is carried out; S3) a point cloud model is established based on 3D laser scanning, concretely, after de-noising, coordinate matching, sampling rarefying and redundancy reduction, a spatial point cloud model of the plotting research object is established based on 3D laser scanning, S3) a 3D model is established based on a close-range multi-visual-angle image by obtaining the point-cloud data model according to the real-scene colors after splicing; S4) multi-source 3D model data fusion and model generation are realized; and S5) a 2D linear drawing is generated on the basis of the 3D laser scanning holographic data.

Description

technical field [0001] The invention relates to the technical field of cultural heritage inheritance and innovation protection, specifically a digital surveying and mapping and three-dimensional private garden space digital surveying and mapping and three-dimensional visualization of private garden cultural heritage based on the multi-view image and three-dimensional laser scanning technology of UAV close-range measurement visualization method. Background technique [0002] Private gardens are an important part of our country’s historical and cultural relics. The current record records of classical garden drawings are based on the principles of garden drawing, setting a certain drawing scale to record the spatial structure and overall layout of private gardens by hand, and according to artificial Surveying records the layout of garden space and garden elements. The way of recording and displaying is mainly in the form of hand-painted horizontal, vertical, section drawings a...
