for project require read product code (similar qr code), webcam. unlike qr code - has many python libraries make scanning easy - need make custom product code - means need custom library. code design simple - 1 shape corresponds '1' , shape corresponds '0'.

know how program reader in python? kind of algorithm should looking into? in terms of programming proficiency i'm beginner (so please try , refrain using complicated terms).

unfortunately image recognition scratch not trivial subject.

there library called opencv may help, think can used python.


if writing scratch, sure image orientated picture above? in case can scan photograph top until hit non-white, , perhaps bottom. finds vertical dimensions. same left , right. have , area, can pick scan line, , count number of black vs white patches (ie, scan across, hit black, scan non black, scan next black etc). simple code this, enough.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
