Problems solved by technology

The essence of change monitoring is to change the characteristics of target objects in different periods. Traditional multi-temporal remote sensing data comparison requires a series of preprocessing operations such as registration and position analysis of the original data to generate result data, and this processing method consumes a lot of manpower. cost and time

Embodiment Construction

[0038] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] The multi-period aerial imagery automatic matching and comparison method of the present invention comprises the following steps:

[0040] (1) Batch import of image data;

[0041] The terminal manages the batch import of image data. The default is non-import status. The terminal triggers the import switch to execute a batch of image import tasks. After the task is completed, the batch is marked as completed. The specific steps include:

[0042] (1.1) Store the image data in the designated directory of the file server, and the directory is named according to the batch number;

[0043] (1.2) The server scans the directory to determine whether it has been imported and marked, and records the batch number through the database engine;

[0044] (1.3) The terminal requests the server to obtain the image data of the uploaded f...

Abstract

The invention discloses an automatic matching and comparing method for multi-period aerial photographic images. The automatic matching and comparing comprises the following steps of: importing image data in batches by means of a terminal, and updating a batch import state; preprocessing the image data, calculating the coordinates of the central point of the image, and storing the coordinates in adatabase; positioning and browsing a three-dimensional spherical scene of the imported batch images; and specifying a specific position in the three-dimensional spherical scene, requesting a server toobtain a to-be-compared image and a comparison image within a certain range of the position, and performing automatic matching of the to-be-compared image and the comparison image. Based on homologous remote sensing images obtained by the same sensor at different time points, original data are directly used for comparison, and intelligent automatic matching is achieved through automatic matchingof the coordinate positions of the center points of the original data. The multi-period high-resolution image automatic matching method is adopted, up-and-down and left-and-right multi-directional rapid automatic matching is supported, specific positions of comparison images are rapidly recognized and marked, and automatic exporting of batch comparison results is supported.

Description

technical field [0001] The invention belongs to the technical field of remote sensing image processing, and in particular relates to an automatic matching and comparing method for multi-period aerial photography images. Background technique [0002] In recent years, my country's aviation and aerospace remote sensing technology has achieved rapid development. Remote sensing data has the characteristics of "three highs" and "three highs". The three highs refer to high spatial resolution, high spectral resolution, and high temporal resolution respectively. Refers to multi-sensor, multi-platform, multi-angle. [0003] Remote sensing image change monitoring technology is an important field of remote sensing scientific research and the main direction of current remote sensing data processing research. It has been widely used in the fields of national economy and national defense construction. The essence of change monitoring is to change the characteristics of target objects in di...
