Problems solved by technology

Among the conventional oil tank height extraction methods based on satellite images, firstly, the laser ranging method and stereoscopic image pairing have the disadvantages of high requirements for equipment and data sources, and weak timeliness and complicated calculations in case of emergency tasks; Second, the shadow length method is based on the arc edge characteristics of the shadow boundary of the oil tank, and there is a problem that the shadow length is difficult to measure accurately, which leads to the problem that the height of the oil tank cannot be accurately calculated

Abstract

The invention relates to a single satellite image-based maximum oil reserve extraction system. The system comprises a satellite remote sensing image browsing module, an image subarea segmentation module, an automatic boundary point capture module, an oil tank shadow height measurement module and an oil reserve calculation module, wherein the satellite remote sensing image browsing module is used for obtaining man-machine interaction information during satellite remote sensing image operation; the image subarea segmentation module is used for extracting a contour edge of an oil tank target so as to facilitate the selection of a key point; the automatic boundary point capture module is used for auxiliary selection of a key point on an arc edge; and the oil tank shadow height measurement module is used for calculating the height of the oil tank on the basis of oil tank shadow information. According to the system, accurate oil tank height extraction can be carried out on the basis of a single satellite image, so that the calculation errors caused by determining same-name arc points via an artificial manner are effectively avoided, and the oil tank height extraction speed is greatly improved.

Description

technical field [0001] The invention relates to the technical field of remote sensing image processing and information extraction, in particular to a maximum oil storage extraction system based on a single satellite image. Background technique [0002] The oil tank is the core facility of the oil reserve base and belongs to the national key construction strategic goal. Its height information is an important content and symbol of oil depot identification, storage capacity estimation and quantitative analysis, and is of great significance in national economic construction and national defense security capabilities. Therefore, it is of great strategic significance to observe the maximum oil storage in a certain area by satellite. The height of the oil pipeline is extracted from the satellite image, and then the volume of the oil pipeline is calculated by the formula so that the maximum oil storage capacity can be determined. Among the conventional oil tank height extraction me...
