Hair Detection in a cup of yogurt

[Haris]

Hello,

 

I am working on a project with a food production plant. I need to implement a scanner that can detect an outside object inside a jar or cup. For Example, if there is a hair fiber or metal piece inside a cup of yogurt that will need to be detected.

 

Any Suggestions what/ which sensors can be used to achieve this objective.

 

Thanks.

you need to use camera. to detect object like hair or fiber you need to have very high resolution camera. 

then you have to take help of MATLAB for image processing. 

like take picture of cup full of yogurt. 

process it using MATLAB function

detect any unwanted object in picture other than yogurt

give alarm type signal

Hi,

 

This is very crucial application.

 

You need to have sharp image processing.

 

As you need to implement this on real time hardware, OpenCV with LINUX on friendlyarm board will be a good option.

 

You can connect USB Webcam with that and perform image processing using OpenCV and drive GPIO pins to give alarm signals etc.

Hi,

 

Thanks alot for your feedback guys. But how can a webcam be used to look through the whole cup. What I mean to say is that a webcam is a normal camera it will only see whats on surface. Right? What if there is a hair strand at the base of the filled cup? how would that be detected?

 

I am waiting for you reply on this matter.

 

Thanks once again.
