问题描述

有关我在大学最后的项目,我正在开发一个车辆牌照检测中的应用。我认为自己是一个中级程序员,但是我的数学知识缺乏上述中学的东西,这使得生产权公式难度比它大概应该是。

For my final project at university, I'm developing a vehicle license plate detection application. I consider myself an intermediate programmer, however my mathematics knowledge lacks anything above secondary school, which makes producing the right formulas harder than it probably should be.

我已经花费的时间量好查找学术论文,如:

I've spend a good amount of time looking up academic papers such as:


  • 在图片



  • Detecting Vehicle License Plates in Images
  • Robust License Plate Detection using Image Saliency
  • Local Enhancement of Car Image for License Plate Detection

当涉及到数学,我迷路了。由于这种测试各种图形图像证明富有成效的,例如:

When it comes to the math, I'm lost. Due to this testing various graphic images proved productive, for example:

然而,该方法仅工作于特定的图像,并且如果所述技术被应用到不同的图像,我肯定会发生较差的转换。我读过关于一个叫做底部形态帽子改造公式,执行以下操作:

However this approach only worked to that particular image, and if the techniques were applied to different images, I'm sure a poorer conversion would occur. I've read about a formula called the "bottom hat morphology transform", which does the following:

基本上,传输形成保持图像的所有暗部细节,并消除一切(包括更大的暗区和亮区)。

接近报告的末尾说明了其有效性,我不能找到这么多的信息,但是文档中的图片。

I can't find much information on this, however the image within the documentation near the end of the report shows its effectiveness.


  • 在C#开发

  • 围项目的英国牌照仅

  • 我可以选择图像作为示范
  • 转换

我需要我应重点发展哪些变换技术,什么算法可以帮助我的意见。

I need advice on what transformation techniques I should focus on developing, and what algorithms can help me.

推荐答案

有多种方法可以采取,但弹出进入脑海的第一个策略是:

There are a number of approaches you can take but the first strategy that pops into mind is to:


  • 发现/研究:确定了一套,你需要确定颜色和字体。如果你的样品图片重新英国大多数板块presentative那么你的工作变得更加容易。例如。简单,奇异的字体和黑色字体在白色背景

  • code:试图找出其中的颜色是predominantly黑白图像的矩形区域。这不是一个可怕的数学重的问题,它应该给你的车牌区域集中。

  • code:做一些清理你的分区这样的转换为纯黑色和白色(单色),也许缩放/移位到一个不错的,紧密的矩形

  • 使用API​​:接着使用现有的OCR(光学字符识别)在你的子选择的图像区域的算法,以便看看你是否能阅读文字

就像我说的,这是很多人的一种策略,但想到为一个需要大量的数学运算量最少的...那是,如果你能找到一个OCR实现,它会为你工作。

Like I said, this is one strategy of many but it comes to mind as one requiring the least amount of heavy math... that is if you can find an OCR implementation that will work for you.
