Multi-process large area network image matching method and device based on feature point library |
| abstract |
A multi-process large area network image matching method and device based on a feature point library belongs to the field of image information processing, and is characterized by comprising the following steps: connecting the main process with a feature point library; determining a database table positioned in the reference image range in the feature point library according to the reference image range and the feature point library; packaging the reference image, the feature point set and all images overlapped with the reference image as subtasks, and circulating until the traversal of the images in the measurement area is completed to form a plurality of subtask packets; the main process pushes all the subtask packets to each subprocess for processing; and the main process receives the return state of each subprocess, and returns the total task state after the main process is finished after each subprocess is finished, so that the image matching is finished. The collection mode of the characteristic points effectively ensures the quantity and the distribution of the characteristic points and meets the use requirement of large-area net adjustment; meanwhile, a sublist naming and storage mode of the feature point database is established, and the efficiency of searching and using the feature points is improved. |
