Problems solved by technology

Segmentation based on edges and regions requires high requirements for color distribution changes. In the cigarette image, the adhesion between cigarettes is serious, so that the color of tobacco leaves and the edge of cigarettes do not change significantly, so these two segmentation techniques are used for Recognition counts are not ideal

Embodiment Construction

[0035] Such as figure 1 As shown, the present invention first preprocesses the image, and the preprocessing steps are as follows: binarize the collected original grayscale image, and remove the smoke frame. After preprocessing, template matching is used for processing. The processing steps of template matching are:

[0036]According to the size and shape of cigarettes, construct a D×D rectangular area as a standard template for describing cigarettes. Due to the existence of noise and different degrees of defects in cigarettes in the preprocessing stage, a cigarette in the actual cigarette image does not completely match the standard template, so a series of similarity criteria are formulated. In the global search, check whether the D×D rectangular area formed by each pixel in the image satisfies the similarity criterion, if so, consider the area as a cigarette, count the cigarettes and count the area. Clear; otherwise, continue to examine the next pixel. The similarity cri...

Abstract

The cigarette batch counting method includes the following steps: firstly, pretreating the obtained original image to obtain image of cigarette portion in cigarette frame interior; adopting template matching method to process image, then counting total sum of cigarettes in obtained said cigarette image. The equipment for implementing above mentioned method includes computer processing system, camera, cigarette fixing device, gated switch, data acquisition card and image processing card. Said invention also provides the working principle of said equipment.

Description

technical field [0001] The invention belongs to the field of image recognition and measurement, in particular to a method and device for counting cigarettes in batches based on template matching. Background technique [0002] Using image recognition to count the number of specific objects has been applied in some fields at home and abroad, but it is mainly concentrated in fields such as cell counting. At present, this technology has not been applied to the counting of cigarettes. . Compared with the counting of cigarettes, although the shape of the cigarettes is more regular and the type is single, due to the large number and high density of the cigarettes in the image, the adhesion between the cigarettes in the image is serious. High-precision counting brings certain difficulties. [0003] At present, there are many processing methods for image recognition technology, among which segmentation technology is the basis. In terms of segmentation technology, there have been m...
