Commodity image correction method, system and equipment, and storage medium

Abstract

The invention provides a commodity image correction method, system and equipment, and a storage medium. The method comprises the following steps that: identifying a plurality of commodity areas in animage f; connecting the center positions of two first target commodity areas to determine a reference line l1, connecting the center positions of two second target commodity areas to determine a reference line l2, and generating a reference line l3 according to the slope average value of the reference line l1 and the reference line l2; connecting the center position of each first target commodityarea with the center position of the nearest second target commodity area to generate a plurality of reference lines l4, and generating a reference line l5 according to the slope average value of theplurality of reference lines l4; and according to a transformation relationship between a horizontal base line of the reference line l3 and the image f and a vertical base line of the reference line l5 and the image f, generating a first transformation matrix so as to generate an image f0 subjected to one-time correction. By use of the method, through two first target commodity areas and two second target commodity areas, a correction reference line can be determined, correction speed is improved, and a correction effect is good.

Description

technical field [0001] The present invention relates to image processing technology, in particular to a commodity image correction method, system, equipment and storage medium. Background technique [0002] When the sensor is being used to capture the image of the target, that is, the optical axis of the sensor is perpendicular to the target plane, and the image collected at this time is a standard image. However, in normal work, it is often impossible to collect standard images. The optical axis of the image sensor and the plane of the target are always at a certain oblique angle. Further corrections are required for them. [0003] In the document titled "Application of Hough Transform in Slant Correction of Chinese Business Card Image", a traditional image correction method is disclosed, which is to first use Hough transform to detect the parallel straight lines in the image, and determine them by the slope of the straight line. Angle and correct. Since the straight lin...

Problems solved by technology

In the collected commodity images of deformed containers, the commodities are relatively dense, the shapes of different commodities are similar, and the objects are many and form irregular geometric shapes. The source of the image collection is unknown, and the sensor camera information cannot be obtained. take effect
