Abstract

The invention relates to a method for constructing an image control distribution network of an unmanned aerial vehicle and a matching method for an optional range of aerial photographs, and belongs to the technical field of remote sensing image processing. The method restores the flight belt model by processing POS data, and automatically calculates the network parameters under the simple parameter input condition; automatically builds the image control distribution network with the assistance of POS data; then, with the assistance of POS data, the image control The distribution network is automatically matched to generate an aerial photo map calibrated with an optional range of image control. The method proposed by the present invention for the construction of UAV image control distribution network assisted by POS data and the optional range matching of aerial photographs can build a highly versatile and evenly distributed image control distribution network through simple parameter specification. And quickly match the aerial photos with more accurate position and moderate range, which are calibrated with optional range of image control. This method has the characteristics of simple parameter setting, standard construction of image control distribution network, and high matching efficiency.

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, ...
