Embodiment Construction

[0020] like figure 1 As shown, a kind of three-dimensional real scene modeling method for hydrological monitoring provided by the present invention comprises the following steps:

[0021] Step 1. Taking the hydrological station as the center to take aerial panoramic images of the hydrological station and its surrounding environment in the air. The photos taken should have moderate contrast, moderate contrast, harmonious light and shade, clear imaging, consistent color tone, and good image quality. The collection range is based on Geographical information determination of the hydrological station and its surroundings;

[0022] Step 2, select the image control point and collect the coordinates of the image control point. The image control point includes landmark points and feature points. Control point coordinates for accuracy evaluation;

[0023] Step 3: Puncture the image control points, and use the high-density point cloud obtained by dense matching of multi-view images to ...

Abstract

The invention provides a three-dimensional live-action modeling method for hydrological monitoring. The method comprises the following steps of: carrying out aerial panoramic image shooting on the hydrological station and the surrounding environment thereof in the air by taking the hydrological station as a center; selecting a photo control point, collecting photo control point coordinates, carrying out precision evaluation on the collected photo control point coordinates, carrying out point pricking on the photo control point, constructing a three-dimensional TIN model under different levelsof detail degrees, and carrying out texture mapping by utilizing the aerial panoramic image to realize three-dimensional model establishment. According to the three-dimensional live-action modeling method, live-action modeling of the three-dimensional model is carried out with the hydrological station as the center and the surrounding environment, the hydrological monitoring model can be established in a targeted mode, the three-dimensional model can be conveniently combined with hydrological monitoring data, and a vivid decision basis can be provided for hydrological early warning decision making due to hydrological simulation; The geographic accuracy of three-dimensional model modeling can be enhanced and the reliability of hydrological simulation can be ensured by utilizing the layout of the image control points and the feature points and the accuracy evaluation of the image control point coordinates.

Description

technical field [0001] The invention relates to a three-dimensional real scene modeling method, in particular to a three-dimensional real scene modeling method for hydrological monitoring.
