摘要

PPROBLEM TO BE SOLVED: To highly speedily and precisely recognize a barcode. PSOLUTION: A target pixel in an image is moved at a predetermined movement interval, and various size image conversion filters corresponding to the movement interval are used, and the pixel whose concentration change in the predetermined reference direction is the largest among the pixels of the image is detected as an edge point candidate, and when edge strength is more than a predetermined threshold value, and the predetermined number of edge point candidates whose edge strength is more than a predetermined threshold, and whose edge directions are within a predetermined angle from the reference direction are continuous in the orthogonal direction of the reference direction, it is decided that the predetermined number of edge point candidates are edge points, and a histogram is calculated by adding the number of edge points to the reference direction and the orthogonal direction, and the position of a barcode in the image is recognized based on the histogram.

要解决的问题:高速准确地识别条形码。

解决方案:以预定的移动间隔移动图像中的目标像素,并使用与该移动间隔相对应的各种尺寸的图像转换滤镜,并且在预定参考方向上浓度变化最大的像素将图像的边缘检测为边缘点候选,并且当边缘强度大于预定阈值时,以及边缘强度大于预定阈值且边缘方向在预定角度内的预定数量的边缘点候选从参考方向开始,在参考方向的正交方向上连续,确定预定数量的边缘点候选是边缘点,并且通过将边缘点的数量加到参考方向和正交方向上来计算直方图,然后根据直方图识别图像中条形码的位置。
