如何从图像识别车辆牌照/号码牌（ANPR）？ [英] How to recognize vehicle license / number plate (ANPR) from an image?

问题描述

我有一个网站，允许用户上传汽车图片，我想把一个隐私过滤器放在车上检测车牌上的车牌，并模糊它们。

I have a web site that allows users to upload images of cars and I would like to put a privacy filter in place to detect registration plates on the vehicle and blur them.

模糊不是问题，但是有一个库或组件（开源的首选），这将有助于在照片中找到许可证。

The blurring is not a problem but is there a library or component (open source preferred) that will help with finding a licence within a photo?

注意事项

1. 我知道没有什么是完美的，这种类型的图像识别将提供假阳性和阴性。


2. 我明白我们可以要求用户选择区域模糊，我们也将这样做，但问题是具体关于以编程方式发现数据;所以像让一个人检查每个图像这样的答案是没有帮助的。


3. 这种软件方法在英国称为自动数字牌识别，但我看不到任何实现


4. 任何语言都是伟大的，虽然.Net是首选。

1. I know nothing is perfect and image recognition of this type will provide false positive and negatives.
2. I appreciate that we could ask the user to select the area to blur and we will do this as well, but the question is specifically about finding that data programmatically; so answers such as 'get a person to check every image' is not helpful.
3. This software method is called 'Automatic Number Plate Recognition' in the UK but I cannot see any implementations of it as libraries.
4. Any language is great although .Net is preferred.

推荐答案

我编写了一个基于JAVA ANPR的C＃版本，但我用OpenCV改变了awt库函数。

I coded a C# version based on JAVA ANPR, but I changed the awt library functions with OpenCV. You can check it at http://anprmx.codeplex.com
