通过图像处理测量物体 [英] Measuring Object Through Image Processing

问题描述

我想通过图像处理来测量物体的长度以0.001mm的精度.
表示 1像素= 0.001mm ，比我需要放大多少倍，我怀疑是否可以实现很多精度或缩放?

I want to measure object''s length through image processing in accuracy of 0.001mm.
means 1 pixel = 0.001mm, than how much zooming i need and i have doubt that that much accuracy or zooming is possible? if possible than is there any camera which can give me that much accuracy or zooming?

推荐答案

看看这个 ^ ]:它将为您提供基于所需图像大小和距离来设置系​​统的标准.

还要看看这些镜头 [

Have a look to this white paper[^] from a provider of camera devices and lenses: it will give you the criteria to set-up your system basing on the required image size and distance.

Have also a look at these lenses[^]: in the section MACRO, there is the MR8/O device, that is able to give you a frame of 0.8 by 0.6 mm when used with a 1/2" CCD. This means that you require a camera with a 1/2" CCD and a resolution at least of 800 by 600 pixels. Well, if you have a look at the camera devices in the same site, you can see that models with a 1/2" CCD have all a resolution of 1280 by 960 pixel. Then, theoretically, you could grab images with a resolution of 0.000625 mm per pixel which is better than what you asked for.
