Single-line code scanner corner problem: Generally, the single-line scanner has obvious restrictions on the angle of the barcode in the plane of the barcode, such as ± 40 degrees. Is this just because the bar code has a small height, and the corner may be too large to cause a single scan line to pass through? Go through the entire bar code ?? If my understanding is OK, then if the bar height is made long enough, can it be guaranteed to read accurately when the corner is large?
Kwen scanner kòd bar ou konprann pa bon. Kwen yo nan paramèt yo jan sa dekri nan figi ki anba a.
Like the barcode scanner described in the figure above, its rotation angle is ± 65 degrees, a check mark indicates the correct angle, and a cross mark indicates the wrong angle.
Ang eskanè ou mansyone ak konprann se aktyèlman yon kesyon de teknik eskanè. Pandan pwosesis optik la, yo ta dwe swiv prensip teknik analiz sa yo:
1) Travès wouj vize ki soti nan vizeur a ta dwe santre sou kòd bar la.
2) Vize scanner barcode a nan kòd bar la epi peze deklanche a pou gwo bout bwa ki vize a nan mitan kòd bar la.
3) Plis scanner kòd bar la se pi pre kòd bar la, se pi piti gwo bout bwa a vize; pli lwen eskanè barcode a se de barcode a, plus travès vize a. Si kòd bar la piti, fè eskanè kòd bar la toupre kòd bar la;
4) Si kòd bar la pi gwo, scanner kòd bar la ta dwe pi lwen kòd bar la, pou li pi fasil pou li kòd bar la kòrèkteman.
