Abstract

The invention provides an automatic modeling method based on oblique photography, and a system and an auxiliary device thereof. The automatic modeling method comprises following steps: planning of a shortest route of an aerial survey region of interest is carried out based on preset route height and overlapping degree information; equipment state information of an unmanned plane and oblique photography equipment of the unmanned plane in aerial survey based on the route is detected; screening of plotting missed areas is carried out based on the equipment state information, replanning of the route is carried out, and aerial survey is carried out until effective aerial survey data covering the aerial survey region of interest is obtained; the aerial survey data is subjected to image correction, texture characteristic matching, per pixel grade dense matching, and aerial triangulation, and a three dimensional plotting model is generated. The automatic modeling method is capable of solving problems such as complex operation process and low intelligent degree in the prior art which are induced because of misunderstanding on the working states of each other.

Description

technical field [0001] The present application relates to the technical field of survey modeling, in particular, to an automatic modeling method, system and auxiliary device capable of simplifying the modeling process of a traditional oblique photography system. Background technique [0002] The appearance of the three-dimensional stratum structure model can directly reflect the stratum distribution in the engineering area, the uniform distribution of a single stratum, whether there is a lack of strata, and the distribution of interlayers. It is especially important for the distribution of strata with important engineering properties. , architectural designers and other relevant personnel provide a comprehensive overview of the stratum distribution. [0003] As the most efficient 3D modeling data acquisition technology at present, oblique photography technology mainly collects data from multiple angles by carrying multiple oblique photography cameras on the photography platf...
