Abstract

The invention relates to the technical field of article identification statistics, in particular to an article classification counting method and device based on image identification and a storage medium. The method comprises the steps of selecting a photo of an object, performing gray scale transformation on the photo, and then performing filtering processing to obtain a binary image; extractingcolor features according to the binary image, then carrying out image graying processing, extracting object contours and geometrical shape features in sequence, and obtaining a target area image through the difference between the original image and the binary image; filling and repairing defects existing in the target area image to obtain an optimized binary image; and performing scanning identification on the optimized binary image in an up-and-down and left-and-right sequence to obtain the number of articles. According to the method, the image quality is improved, so that the image area is complete, judgment of a program on a frame can be reduced, the speed is increased, and meanwhile, the error rate is reduced by extracting geometrical shape features.

Description

technical field [0001] The invention relates to the technical field of item identification and statistics, in particular to a method, device and storage medium for item classification and counting based on image identification. Background technique [0002] Items need to be classified and counted in an assembly line or a place where items are mixed. At present, manual statistics are generally used for classification and counting. This method is time-consuming and inefficient. [0003] Image recognition is a basic technical means of artificial intelligence. At present, image recognition is by extracting the features of each pixel in the image to be recognized, and comparing it with the features of each pixel in the existing image. When the similarity of point features is within the set range, the item in the existing image is output as the item in the image to be recognized. But the problem is that the image processing function is insufficient: after the photo processing of...
