是否有DLL，SDK或libary可以使用代码中的网络摄像头读取条形码？ [英] Is there a DLL, SDK or libary that can read barcodes using a webcam inside code?

问题描述

我一直在寻找一种方法来使用网络摄像头（罗技轨道：v-uu22a）来读取各种条形码种类）来自vb.net代码。我找到了两个可以与网络一起工作的产品（katahashi和bcweb），但是它们都来自他们自己的guis。是否有一些软件会使用来自内部代码的网络读取条形码？



谢谢，

Hi,

I've been looking for a way to use a web cam (logitech ar orbit:v-uu22a) to read a barcode (of various kinds) from inside vb.net code. I have found two products (katahashi and bcweb) that will work with a web came but they run from their own guis. Is there some software that will read barcodes using a web came from inside code?

Thanks,
Neil<<br mode="hold" />
What I have tried:

Did google search and read through at least 50 products

推荐答案

网络摄像头是一回事，条形码识别是另一回事。老实说，一次又一次地回答两个问题回答这么多次是不好的。例如，参见：

网络摄像头，

条形码。



这是在CodeProject上...



你能用它吗？首先，它取决于您想要涵盖的条形码标准。

Web camera is one thing, barcode recognition is another one. Honestly, it would be bad to answer again and again two questions answered so many times. See, for example:
Webcam,
Barcode.

And this is on CodeProject along…

Can you use it? First of all, it depends on the barcode standards you want to cover.

谢尔盖，



感谢您的回复。我会说你的回答有点令人困惑。首先，除了摘要外，相机与条形码并不完全无关。如果你看一下你要求我看的一些帖子列表，你会看到至少两个做我问过的问题：Katanashi和bcweb。显然，如果从网络摄像头读取条形码的概念只是愚蠢，那么这些人就不会赚钱。另外还有两种带有gui包装的产品可以做同样的事情。



我需要能够从vb.net代码读取条形码所以Katanashi和bcweb是出。然后有bytescout和dynamsoft完全符合我的要求。但是，与所有几乎没有竞争对手的产品一样，他们正在为他们的软件收取微不足道的费用，我不想将这些费用转嫁给我的公司。 START的约为

Sergey,

Thanks for responding. I will say that your response was a bit confusing. Firstly, cameras are not totally unrelated to barcodes except in the abstract. If you'll look at some of the list of posts you asked me to look at you'll see at least two sdks that do what I asked about: Katanashi and bcweb. Clearly these people wouldn't be making any money if this concept of a barcode being read from a webcam is just "silly" as you imply. In addition there are two products with gui wrappers that do the same thing.

I need to be able to read the barcodes from vb.net code so Katanashi and bcweb are out. Then there is bytescout and dynamsoft that do exactly what I want. However, as with all products that have almost no competition, they are charging rediculous fees for their software which I don't want to pass on to my company. The licensing for both START at about

可能有更多的产品，但我还没有找到它们。



我会指出在我漫长的职业生涯中，我多次发现那些支持概念上不同的产品并加入它们的产品，从发展的曙光开始就存在。这一切都取决于市场。有时我找不到任何帮助我，有时候我找到了十种产品。关键是你必须根据产品可能存在的假设进行任何搜索，因为它经常是。这是像这样的搜索的概念框架，而不是两件事不适合的抽象概念。



我已经在这两天了，写信给各种各样的人，在某种程度上，你对加入相机和条形码有问题是正确的。我发现由于焦点问题，颜色和光线问题，相机有困难。相机不会立即擅长条码阅读。我现在知道了;我之前没有。仍有可能将它们合并，有人认为这样做是个好主意。我最初对使用网络摄像头的兴趣是通过不必购买其他设备来节省资金。但似乎使用条形码阅读器可能更便宜。刚刚发现了。活到老，学到老。事实证明，我认为网络摄像头很便宜，我们使用成本

There are probably more products than this but I have not found them.

I will point out that in my long career that I've found many times that products that support conceptually disparate products and join them, have existed from the dawn of development. It all depends on the market. Sometime I have found nothing to help me, sometimes I have found ten products. The point is that you have to approach any search based on the assumption that the product may be there because it often is. That is the conceptual framework for searches like this, not the abstract idea that two things don't fit together.

I have been at this for two days, writing to various people and to a certain extent you are right about there being a problem joining cameras and barcodes. I JUST found out that there are difficulties with cameras due to focus issues, issues of color and light. Cameras are not immediately that good at barcode reading. I know that now; I didn't before. Still it is possible to merge them and someone thought it was a good idea to do do so. My initial interest in using web cams was to save money by not having to buy another device. But it seems that it may be cheaper to use barcode readers. Just found that out. Live and learn. And it turns out that the web cam I thought was cheap that we use costs
