摄像机作为条形码阅读器 [英] video camera as bar code reader

问题描述

我的项目建议是关于使用可以远距离阅读的摄像机的条形码阅读器。但是，我对此有所了解。我的问题是：如何使用摄像机读取远处的条形码？我将使用什么条形码（具体）来处理以及使用什么类型的解码来简化工作（如果有更简单的话）？

我非常感谢您的善意并非常感谢您阅读本文。

救我T_T

My project proposal is about a Bar code reader using video camera that can read at a great distance.But,I know a little about this. My questions are: How can I read bar code in a distance using video camera? What bar code(specific) to deal and a what type of decoding will I use to make work simpler(if ever there is simpler)?
I really appreciate your kindness and thank you very much for reading this.
save me T_T

推荐答案

首先，如果您要远距离阅读条形码，您的相机将需要相当高的分辨率。



最简单的方法是拍摄快照，识别图像中的条形码，旋转它使其水平（假设像UPC一样的条形码），然后读取它。



哪种条形码取决于你的用法。例如，您在商店购买的所有物品都有UPC，但如果您想在条形码中找到其他信息（例如序列化纸箱＃），您会想要使用像UCC（GS-1）这样的东西。条形码。



这应该让你开始，因为你的问题对于条形码的实际使用有点模糊。如果您有任何其他问题，请告诉我。

First, if you're going to be reading barcodes at a great distance, your camera will need pretty high resolution.

The easiest way is going to be to take the snapshot, identify the barcode within the image, rotate it so it's horizontal (assuming a 1D barcode like a UPC), and then read it.

Which kind of barcode depends on your usage. As an example, everything you buy at the store has UPCs, but if you're looking to have other information in the barcode (such as a serialized carton #), you'll want to use something like a UCC (GS-1) barcode.

This should get you started, as your question is kinda vague as to the actual usage of the barcodes. Let me know if there's anything else you have questions with.

请记住视频只是一系列静止图像，因此您的问题是如何从图像中获取条形码。我建议你阅读这三篇文章

从图像中读取条形码 [ ^ ]

< a href =http://www.codeproject.com/KB/graphics/barcodeimaging2.aspx>从图像中读取条形码 - II [ ^ ]

从图像中读取条形码 - III [ ^ ]

Remember video is just a series of still images, so your question is how you get barcodes from an image. I would suggest you read these three articles
Read Barcodes from an Image[^]
Reading Barcodes from an Image - II[^]
Reading Barcodes from an Image - III[^]

我的问题就像你的问题一样。因此，如果你已经解决，请帮助我！

我的要求是使用平板电脑的相机阅读条形码
