Image capture equipment and scanning target extraction method and device thereof and storage medium

Abstract

The invention discloses image capture equipment and a scanning target extraction method and extraction device thereof and a storage medium. The scanning target extraction method comprises the steps that a scanning area image is acquired; the closed contour lines of all the objects in the scanning area image are extracted, wherein the objects include a target object; the first angular points of the closed contour lines are recognized according to the first preset rules; whether the number of the first angular points is consistent with that of the preset angular points is judged; if the judgment result is yes, the image of the target object is extracted from the scanning area image according to the first angular points; and if the judgment result is no, the second angular points of which the number is consistent with that of the preset angular points are determined according to the closed contour lines and the preset algorithm, and the image of the target object is extracted from the scanning area image according to the second angular points. With application of the method, the target object can be effectively extracted from the scanning area image when the target object is arbitrarily shaped or the interference object exists so that the scene adaptability of the image capture equipment for scanning can be enhanced.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to an image capture device, a scanning target extraction method, an extraction device and a storage medium. Background technique [0002] At present, scanners have been widely used in our life, work and study. With the development of science and technology, the use of image capture devices for scanning has gained popularity among the public due to its convenience and speed. [0003] However, there is a problem that the image capture device is not adaptable to the scene when it is used for scanning. For example, when the image capture device is used to scan the target object, other objects (such as fingers, interfering objects) enter the scanned image or directly cover the target object. When the area, or the target object is irregular or incomplete, or the target object does not completely enter the scanned image, the target object cannot be well recognized. Summary of t...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a scanning target extraction method, which aims to solve the problem that the image capture device is not very adaptable to the scene when it is used for scanning, and the target object cannot be well recognized and extracted when the shape of the target object is uncertain or there are disturbances.
