CAM M7 availability after H7 release
hello I just finished the design of a vision system for industrial application. The system is designed to work as an auxiliary system for the machine that we are producing and selling worldwide. Today I received the news of the next release of H7 version and I am quite concerned about the discontinu...

Re: Measure distance between two paper bands
Ok. I'll send it tomorrow.
For the time being you can image that in white paper the cam is detecting a threshold due to some shadows and it result in a blob detection.
The core of the program I am using is practically the one you suggested a few posts above this.
Bye

Re: Measure distance between two paper bands
Hello I made some steps ahead on the project. I decided to cover the machine width with several CAMs and I cannot predict if the the narrow gap between paper slits will be in front of a camera (maybe some of them will see only a white paper sheet). I experienced that in this case the CAM is detectin...

Re: CV inspection bar
Thank you.
To connect the CAM to the CAN bus or do I need a transceiver?
I assume the board you suggested is required on PC side. Is it correct?

CV inspection bar
Hello I am designing a an inspection bar where I need to position up to 50 CAMs in order to cover certain length. All CAMs need to communicate with a PLC (or PC) to transmit some data acquired. Can you suggest the best solution to connect and address such amount of devices and how to power them (con...

Re: Future wishlist
Hello,
I would be very interesting to have an ethernet shield with PoE technology for industrial use.

Re: Measure distance between two paper bands
Yes, same mistake is on the online documentation.
By the way, the line:
threshold = img.get_histogram().get_threshold()
still return the error " 'histogram' object has no attribute 'get_threshold' ".
The same if i try to write threshold in the wrong way.

Re: Measure distance between two paper bands
Thank you for the code!
Actually my IDE shows on the bottom right corner "Firmware Version: 2.7.0 - [latest]"
The IDE version is 1.8.1.
I guess it already the newer one....

Re: Measure distance between two paper bands
Hi,
by re-reading your message I just realized that we had a misunderstanding: actually I need to measure the gap of a slit between two piece of paper. I think the concept should be the same but, maybe, a littele more difficult to chose the right blob (I cannot pick the widther one...).

Re: Measure distance between two paper bands
Thank you very much for your suggestion.
If you can provide some lines of code it would be very
well appreciated, so will have some base to start.

Measure distance between two paper bands
Hello, I would like to use an OpenMV M7 to measure the gap between two paper bands while they run between two rolls on a production machine (I am attaching a picture took inside the machine).
