Abstract

The invention relates to a method for constructing an image control distribution network of images of an unmanned aerial vehicle and matching optional ranges of aerial photographs, and belongs to the technical field of remote sensing image processing. The method is as follows: processing POS data, recovering an aerial strip model, and in the case of simple inputting of parameters, automatically calculating network type parameters; automatically constructing the image control distribution network under assistance of the POS data; and under the assistance of the POS data, automatically generating the aerial photographs calibrated with image control optional ranges by automatic matching of the image control distribution network. Through use of the POS data assisted method for constructing the image control distribution network of the images of the unmanned aerial vehicle and matching the optional ranges of the aerial photographs, through simple parameter assignment, the strong-universality uniform-distribution image control distribution network can be constructed, and the accurate-position moderate-range aerial photographs calibrated with the image control optional ranges can be fast matched. The method has the advantages of simple parameter setting, construction of image control distribution network type specification, high matching efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing, in particular to a method for constructing an image control distribution network of unmanned aerial vehicle and matching the optional range of aerial photographs assisted by POS data. Background technique [0002] UAV aerial photography technology is a new digital surveying and mapping aerial photography technology after traditional aerial photography. Compared with traditional aerial photogrammetry, UAV aerial photography has the advantages of flexible take-off and landing, less affected by weather, and low cost. features. At present, the orthophoto map (DOM) and digital line map (DLG) produced by low-altitude digital remote sensing image technology can meet the accuracy requirements of 1:5000, 1:2000 and 1:1000 scales. [0003] The POS system, also known as the IMU / DGPS system, can measure the position and attitude of the sensor in real time during the imaging process, ...
