Abstract
20th Signal Processing and Communications Applications Conference, SIU 2012; Fethiye, Mugla; Turkey; 18 April 2012 through 20 April 20123B lazer tarayıcılar yüzey geometrisinin yakalanması için yaygın olarak kullanılan sistemlerdir. Geleneksel lazer tarayıcı sistemler bir adet lazer ışık kaynağına sahiptir. Bu çalışmada iki adet lazer ışık kaynağına sahip bir 3B lazer tarayıcı ele alınmıştır. Bu tarayıcı özellikle sahnelerdeki örtme etkisinin en küçüklenebilmesini sağlamaktadır. Ancak birden fazla lazer kaynağına sahip lazer tarayıcılar için kalibrasyon önemli bir problem olmaktadır. Çalışmamızda bu sistemlerde karşılaşılan kalibrasyon problemi tanımlanmıştır. Bu problemin çözümü için taranan sahnelerdeki dikgenlik, eş-düzlemsellik bilgileri kullanılmıştır.3D laser scanners are widely used systems to capture surface geometry. Conventional laser scanners have one laser source. In this study, a laser scanner systems with two laser sources is considered. The scanner is capable of minimizing the effect of occlusion in the scene. But the calibration issue becomes more complicated for scanners having more than one laser source. In our study the calibration problem of such scanners are defined. Some scene specific informations like orthogonalities, co-planarities are used for solving this problem. © 2012 IEEE
