Abstract

Izgudrojums attiecas uz optikas nozari, konkrētāk, lāzertehnoloģijām, vēl konkrētāk, uz industriālo lāzeru, jo īpaši lāzera stara, pozicionēšanu.Piedāvātais paņēmiens lāzera pozicionēšanai interesējošo objektu apstrādā ar lāzera staru, kas ietver attēla iegūšanas soli, kam seko interesējošo objektu identificēšana attēlā. Interesējošais objekts var būt nezāle vai cits lauksaimniecībai nelabvēlīgs augs vai auga daļa. Paņēmiens raksturīgs ar to, ka tiek realizēta apstrādājamā laukuma sadalīšana apstrādes līnijās, kam seko apstrādājamo līniju pozīciju telpā aprēķināšana, pēc kā seko līniju apstrāde ar lāzera ģenerētu lāzera staru. Viens cikls ar augstāk minētajiem paņēmiena soļiem tiek realizēts līdz 25 milisekundēm.Tehnoloģija ļauj ar lāzeru apstrādāt kustībā esošu objektu, vai apstrādāt nekustīgu objektu ar kustībā esošu lāzeru, ar milimetru precizitāti vai precīzāk.
