Aerial photography integrated method

Abstract

The invention provides an aerial photography integrated method. A small aerial photogrammetry system based on digital images is adopted, and the system is composed of an ultra-light aircraft platform,a single-sided array digital aerial camera and a data processing system. The method is based on aerial photogrammetry of the digital camera and the ultra-light aircraft platform, and comprises the following steps: Step 1, calibration of the digital camera: solving parameters of the digital camera by using a corresponding relation between sequence images shot when the digital camera moves by adopting a self-calibration method; Step 2, field data acquisition; 3, indoor data processing, including: using a method of correcting a single-image field ground object acquisition result by using indoorencrypted data and a DEM to obtain a space coordinate, or obtaining space coordinates of the ground object by adopting a post-intersection-pre-intersection method through two-image stereo, carrying out data splicing and feature clipping, forming ground object data with the map sheet as the unit, and carrying out format conversion to an editing system to directly carry out aerial survey indoor editing operation.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to an integrated aerial photography method. Background technique [0002] Photogrammetry and remote sensing is the process, science and technology of obtaining reliable information about the earth, its environment and other objects from non-contact imaging and other sensor systems through recording, measurement, analysis and expression. Among them, photogrammetry focuses on extracting geometric information, and remote sensing focuses on extracting physical information. That is to say, photogrammetry obtains information about the earth, its environment and other objects from a non-contact imaging system through recording, measurement, analysis and expression. The art, science and technology of reliable information on geometry, properties, etc. Aerial photogrammetry is an aircraft flying according to a certain required route. For ground photography, there is a certain degree of o...

Problems solved by technology

[0003] In the traditional aerial photogrammetry (aerial survey) mapping process, the field adopts the method of field mapping and small pen tip ink, and the internal industry then conducts mapping. However, this method can no longer meet the needs of digital production. The integration method of aerial survey and internal field, which is completed directly on the original image, has become the development trend of aerial survey and mapping.
