拉直圆圈？ [英] Straightening Out A Circle?
问题描述
伙计，
我的扫描图像是圆形的，并且在
中间包含一条痕迹（对于那些熟悉的人来说）卡车是一个行车记录仪
图表！）。
我想压扁把它弄成一条直线。我似乎无法找到
任何可以为我做这件事的控件。
有没有人有任何想法，或者我会有什么想法写一些代码来做它
逐像素？
先谢谢。
克雷格。
Folks,
I have a scanned image which is circular, and contains a trace in the
middle of it (for those of you familar with trucks it is a tachograph
chart!).
I want to "flatten" it out, into a straight line. I can''t seem to find
any controls which might be able to do this for me.
Does anyone have any ideas, or will I have to write some code to do it
pixel by pixel??
Thanks In Advance.
Craig.

我不喜欢我认为有标准课程，你必须自己编写。
它会是这样的：
- 找到位置/大小/中心圆圈
- 找到轨迹的起始角度
- 跟踪角度/半径坐标中的轨迹
（可能：单步执行对于给定角度，具有一定分辨率的角度范围
找到跟踪线所在的半径。
- 在新x / y图中绘图，x =记录角度，y =记录的半径
好项目。对不起，我不能用如何进一步帮助你。这些步骤。

I don''t think there are standard classes for this, you have to write your own.
It would be something like:
- find the position / size / center of the circle
- find the start angle of the trace
- follow the trace in angle/radius coordinates
(possibly: step through the angle-range with some resolution, for a given angle
find the radius where the traceline is)
- plot in new x/y graph, x=recorded angle, y=recorded radius
Nice project. Sorry, I can''t help you further with the "how" of these steps.

嗯，你刚才这样做过吗？如果是这样的话，那么手动压扁它是不是更容易？
如果你需要这个是动态的，那么先生。 Kesting'的建议
是真的...这篇文章应该为你提供访问和操作图像像素数据的所有细节

well, are you only doing this once? if so, wouldn''t it just be easier
to flatten it out by hand?
If you need this to be dynamic however, then mr. Kesting''s suggestion
holds true ... here is an article that should give you all the details
on accessing and manipulating the pixel data of an image.
