An urban automatic optimization modeling system based on a tilt camera

Abstract

The invention discloses an urban automatic optimization modeling system based on a tilt camera. The system comprises a tilt image collection module, a tilt image processing module, a tilt model generation module, a modeling recognition module and a modeling optimization module, the tilt image collection module collects omnibearing ground object data of front, rear, left, right and vertical anglesthrough a tilt camera, and position information during photographing is recorded through GPS equipment. And the modeling of the whole city can be rapidly and accurately formed. And the range of the model needing to be optimized can be reduced, and the next step of targeted optimization is facilitated. According to different types of models and reasons for generating problems, targeted optimizationis carried out, data are obtained from existing resources, the models with the problems are optimized one by one, leakage checking and deficiency filling are carried out on overall city modeling, andthe integrity and accuracy of the overall city modeling are further improved.

Description

technical field [0001] The invention relates to a city modeling system, in particular to a city automatic optimization modeling system based on an oblique camera. Background technique [0002] From the point of view of the data collection method, the traditional image is to continuously capture photos of the ground through the aerial camera mounted on the aircraft, and then the image data is obtained through a series of internal processing. Viewing angle is perpendicular to the ground. In the oblique photogrammetry test, five cameras equipped with an aircraft or a UAV are used to shoot ground objects from multiple directions, and then through a series of processing such as geometric correction, adjustment, and multi-view image matching in the office to obtain ground objects. Comprehensive information data.

AI Technical Summary

Problems solved by technology

[0003] In existing urban modeling, due to the influence of actual conditions and shooting equipment, data collection errors or local data cannot be collected easily, resulting in modeling errors or incomplete modeling. For example, glass is laid on the side of a high-rise building, forming a high-rise building. The reflection phenomenon makes the camera "blind" when acquiring plane information, making the information in this area inaccurate

As well as the low-height buildings under the viaduct, due to the occlusion of the viaduct, the data cannot be completely collected, etc.
