Problems solved by technology

[0003] However, at present, the device for collecting images in oblique photography technology is generally a camera, and the shooting interval of the camera is relatively long. Due to the influence of limiting factors such as the angle of exposure, some surface information cannot be obtained, which makes the three-dimensional existence information of the real scene generated later. Missing, at present, it is generally processed by manual repair, which is time-consuming and labor-intensive

Abstract

The invention relates to an oblique photography system, which comprises a photography main body provided with several cameras and a mounting plate and a remote sensing platform for carrying the photography main body. The mounting plate is provided with a plurality of mounting sub plates, wherein every two planes where the mounting sub plates are located intersect with each other. The cameras are mounted on the mounting sub plates. The cameras have the shooting speed of 30 frames or above per second, image data with a larger overlap degree is obtained after the video data is divided into frames, the field angle of the cameras is wider, and a wider range of data can be shot, which can reduce the loss of information in the real-scene three-dimensional generation. The application of the oblique photography system can greatly reduce manual repair work and make later processing faster.

Description

technical field [0001] The present application relates to the field of remote sensing, in particular to an oblique photography system. Background technique [0002] Oblique photography technology is a high-tech developed in the past ten years. This technology obtains rich high-resolution textures of building top surfaces and side views by synchronously collecting images from multiple perspectives. It can not only truly reflect the situation of ground objects, obtain object texture information with high precision, but also generate real 3D models through advanced positioning, fusion, modeling and other technologies. [0003] However, at present, the device for collecting images in oblique photography technology is generally a camera, and the shooting interval of the camera is relatively long. Due to the influence of limiting factors such as the angle of exposure, some surface information cannot be obtained, which makes the three-dimensional existence information of the real s...
