The invention provides a method for identifying the shooting point plotting position of a remote-sensing image interpretation sample. The method comprises the following steps: extracting an original image block on which the shooting point plotting position is positioned; identifying the shooting point plotting position with a spectrum method according to the extracted original image block; when identification is not realized by the spectrum method, identifying the shooting point plotting position with a gradient method according to the extracted original image block. By adopting the method, the problem of incapability of full data checking of the remote-sensing interpretation sample is solved, the retrieval efficiency is increased, the accuracy of the shooting point plotting position is increased, and quality control of a data sample in the census of national conditions is facilitated.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for identifying the plotting position of a shooting point of a remote sensing image interpretation sample. Background technique [0002] With the development of society and economy and people's emphasis on ecological civilization, the census of geographical national conditions, as an important means of obtaining information on geographical national conditions, has received strong support from the government and land and other departments. The census of geographic national conditions can help the government to find out the current situation and spatial distribution of our country's natural and human geographical elements, provide an important basis for formulating and implementing national development strategies and plans, optimize the pattern of land and space development and the allocation of various resources, and promote ecological and environmental pr...
