Method, device and equipment for extracting shadow region of to-be-detected object and storage medium

Abstract

The invention discloses a to-be-detected object shadow region extraction method, device and equipment and a storage medium. The method comprises the steps: receiving a remote sensing image, and obtaining an extrapolation image of a to-be-detected object in the remote sensing image; determining a target color space expressing the extrapolation image, and judging whether the target color space is apreset first color space or not; if yes, color space conversion processing of a preset second color space is conducted on the target color space, a target conversion image is obtained, and the secondillumination threshold fluctuation range of the preset second color space is smaller than the first illumination threshold fluctuation range of the preset first color space; and determining the shadowregion of the shadow of the to-be-detected object according to the target conversion image. The technical problem that the shadow extraction effect of the to-be-detected object is unstable is solved.

Description

technical field [0001] The present application relates to the field of artificial intelligence technology of financial technology (Fintech), and in particular to a method, device, equipment and storage medium for extracting the shadow area of ​​an object to be detected. Background technique [0002] With the continuous development of financial technology, especially Internet technology and finance, more and more technologies are applied in the financial field, but the financial industry also puts forward higher requirements for technology, such as the extraction of the shadow area of ​​the detected object in the financial industry There are also higher requirements. [0003] That is to say, the current era is the era of crude oil. Real-time understanding of crude oil reserve data in various countries is directly related to national security. At present, crude oil reserve estimates or forecasts are usually monitored by satellites to obtain remote sensing images of crude oil p...
