barcode reader using esp32 wrover - is it feasible?

[stoikos]

Hi,
Is it feasible to have a barcode reader device based on esp32? is there a barcode decode library that I can compile ? any ideas or suggestions?

Sure it's feasible. Do you already know what input method for the barcode you're going to use? Spinning laser, linear CCD, camera, light pen, ...?

I have some requirements that narrow down my selection of input methods to use.
a. device must be able to recognize barcodes on a curved surface (like a bottle)
b. bottles will be on a conveyor belt
c. low light environment. no external light permitted.
d. there may be people looking into the device

given the above I think lasers are out of the question, linear ccd need exact positioning to read the barcode, so only a camera (like OVM9724 720p https://www.ovt.com/cameracubechipproducts/720p ) fits the bill.
