Hi all, sorry for the possible newbiew question !
I would like to know if i can read a barcode on a rotating tire or a car travelling at 50 km/h, to have a roung calculation of FOV lens and distance i would like to know what kind of FPS i can expect from the OpenMV Cam on this matter. Barcode is a simple numeric standard barcode.
Thanks much apreciated.
Hi, that seems really hard.
Can you provide some more details on what exactly you are trying to do and the problem setup?
50km/h is a very fast rotation. The wheel would just be a blur generally.
Yes that’s the problem. i can have a strobe light to have the pictures less blurred but the FPS is still a question mark.
The idea is to scan a barcode while a racing car passes trough the pitlane and get the barcode to save the serial number of the tire and the id of the car that passes.
I can have some control on distance lights and so so.
Yeah… so, I mean, just realize the barcode is going to be relatively small, not illuminated, and you need to calibrate a strobe on.
This is like a $1M+ system if you hired a professional company to design this.
I’d recommend you to buy an OpenMV Cam with the global shutter sensor that can be triggered to get an idea for the FoV and frame rate. Barcode code detection goes slower or faster depending on how many lines of confidence you want. E.g. you have it scan the image 10-20 times top to bottom decoding the same barcode. The number of them that match/agree is your confidence score. If you just do this for a single line in the image then it will be fast but you’ll not have any error checking.
