Abstract

The invention discloses a high-resolution remote-sensing image change detection method facing targets and based on an integrating strategy. A high-resolution optical remote-sensing image registered through two time phases is input, and multi-resolution cutting is carried out on the input high-resolution image; change detecting is carried out on divided units (targets), and the mean value and the variance of each target are calculated; the mean values and the variances of all the targets are combined to form a new vector, changing regions and non-changing regions of the image are fixed according to chi-squared distribution; detection results are integrated on the basis of a voting method, and accordingly a change detection result is more stable and more accurate.

Description

technical field [0001] The present invention relates to high spatial resolution optical remote sensing image change detection, specifically an object-oriented high resolution remote sensing image change detection method based on fusion strategy, which can be used to solve the high spatial resolution multispectral remote sensing image change detection accuracy The problem that is not high belongs to the field of remote sensing image processing technology. Background technique [0002] With the continuous accumulation of multi-temporal high-resolution remote sensing data and the successive establishment of spatial databases, how to extract and detect change information from these remote sensing data has become an important research topic in remote sensing science and geographic information science. According to remote sensing images of different time phases in the same area, dynamic information such as cities and environments can be extracted to provide scientific decision-mak...
