Abstract

The invention relates to the technical field of data measurement, in particular to a method for measuring three-dimensional scene data, and the method comprises the following steps of exploring and analyzing a three-dimensional scene measurement area; setting up a measurement tool on the station control point; selecting a low-altitude aerial drone of a suitable model according to the three-dimensional spot scene, wherein the drone performs aerial survey to acquire panoramic real-time images of high-precision image data, sorts the obtained image information, and extracts and comprehensively analyzes the measurement information; and organically blending the three-dimensional model in S7 and the panoramic real-time images in S5 to achieve stereoscopic data measurement of the 3D scene. The method provided by the invention can quickly measure the data of the three-dimensional scene, and the obtained three-dimensional scene is accurate in measurement data and high in efficiency, thereby greatly reducing the labor intensity of the measuring personnel and reducing the measurement cost of the three-dimensional scene data.

Description

technical field [0001] The invention relates to the technical field of data measurement, in particular to a method for measuring three-dimensional scene data. Background technique [0002] The measurement of 3D scene data is to measure the 3D data of the space. According to the 3D data of the space, the size and volume of the space can be quickly evaluated and estimated, which has good practical significance. [0003] Early three-dimensional space surveying and mapping used simple tools, such as rope rulers, step bows, etc. for measurement. These measuring tools are all mechanical, and mainly focus on measuring distance, and the measurement accuracy is low. At present, the existing three-dimensional space surveying and mapping technology can realize the measurement of any spatial position, angle, distance and other information in the real world. When conducting on-site surveying and mapping, surveyors usually pre-judge which data needs to be measured, and then conduct actu...
