Problems solved by technology
The control points collected in the field generally have a long cycle and high cost. For the situation where the accuracy of surveying and mapping products is high, the above method can meet the requirements. However, there are great obstacles to the production of rapid emergency surveying and mapping products under harsh conditions.
High-precision remote sensing data is often obtained through complicated channels and less coverage area
[0003] Therefore, there is an urgent need for a technical solution that can solve the long production cycle of surveying and mapping products, low precision and rapid drawing in emergency situations.

[0039] Generally speaking, remote sensing image correction is to establish a mathematical relationship between the object space information and the image space information on the remote sensing image, and then correct the remote sensing image through the established mathematical relationship. Among them, there are generally two ways to obtain the object information of remote sensing images, one is the control points collecte...

The invention provides an automatic fast correction method based on online remote sensing satellite images, comprising: matching tile data positions; reading tile data; extracting feature points in memory; processing pixel coordinates of feature points to determine search image areas; Image control point matching; calculation of polynomial coefficients; solution to corrected image coordinates; image position correction and resampling. Based on the method of online remote sensing satellite image resources, the whole process of data processing does not fall into the disk, the determination of the number of tiles and the determination of the search range are optimized, and the speed and accuracy of image processing are taken into account, making it possible to display images in real time after correction.
Description
technical field [0001] The present invention relates to the field of remote sensing, in particular, to the field of remote sensing image correction. Background technique [0002] The traditional image geometry correction generally uses the control points collected in the field or the high-precision remote sensing base map data as the reference data, and uses the matching points matched with the high-precision remote sensing base map data as the control point data. The control points collected in the field generally have a long period and high cost. For the situation where the accuracy of surveying and mapping products is high, the above method can meet the requirements, but it has great obstacles to the production of rapid emergency surveying and mapping products under harsh conditions. The acquisition channels of high-precision remote sensing data are often complicated and the coverage area is small. [0003] Therefore, there is an urgent need for a technical solution that...
