简单的BLOB检测算法 [英] Simple BLOB detection algorithm

问题描述

你好.
我目前正在开发一种自动驾驶汽车，它将学习一条轨道并以最佳速度运行它.
我的问题是我需要使用摄像头来跟踪轨道并在其上引导车辆.轨道完全是白色的，中间有一条黑线作为参考.
相机是单色的，基本上返回一个128大小的数组，其中包含用于相机读取的值.

我需要一个可以检测到黑线的VB语言.这听起来很自私和懒惰，但是我在这个领域有0个经验，而且我的时间已经用完了.

请说明我该如何处理.欢迎任何准则或示例代码.

Hello.
I am currently developing a autonomous vehicle that will learn a track and run it at an optimised speed.
My issue is that I need to use a camera to follow the track and guide the vehicle on it. The track is completely white and has a black line in the middle as a reference.
The camera is monochromatic and basically returns a 128 sized array with values for the camera''s reads.

I would require a VB alogrithm that would detect that black line. This may sound selfish and lazy but I have 0 experience in this area and I am running out of time.

Please explain how I should approach this. Any guidelines or sample codes are welcome.

推荐答案

听起来像您承担了一个超出您能力的项目.我在有关图像处理的系列中(这里是Code Project)写了一些有关边缘检测的文章.他们可能会有所帮助.

Sounds like you took on a project that was beyond your means. I wrote some articles on edge detection in my series on image processing, here on Code Project. They may help.

首先要看的是AForge.NET，请参阅:

http://en.wikipedia.org/wiki/AForge.NET [ http ://www.aforgenet.com/ [ ^ ].

特别是，请参阅以下文章: http://www.aforgenet.com/articles/shape_checker/ [ ^ ].

另请参阅AForge.NET作者，CodeProject成员Andrew Kirillov的文章: http://www.codeproject.com/Members /Andrew-Kirillov [ ^ ].另一个要查看的CodeProject成员是Chesnokov Yuriy， http://www.codeproject.com/Members/Chesnokov-Yuriy [< ^ ].

(可选)查看以下库:

OpenCV， http://en.wikipedia.org/wiki/OpenCV [ http://opencv.willowgarage.com/wiki/ [ ^ ] ，

VXL， http://en.wikipedia.org/wiki/VXL [ http://vxl .sourceforge.net/ [ ^ ].
