Abstract
Bakalaura darbs ir uzrakstīts latviešu valodā, datorsalikumā uz 37 lapaspusēm. Tas satur 22 attēlus, 1 tabulu, 3 pielikumus un 28 atsauces uz literatūras avotiem.
Darba mērķis: Izpētīt krāsu stereoredzes radīto dziļuma sajūtu un tās pamanīšanas slieksni atkarībā no apgaismojuma, kā arī stereoskopiskā efekta izmaiņu, daļēji aizklājot redzes lauku.
Metode: Krāsu stereoredzes novērtēšanas tests (datorprogramma), kas sastāv no perifēra un centrāla kvadrāta ar dažādām purpura krāsas diferencēm.
Secinājumi: Krāsu stereoredzi raksturo pamanīšanas slieksnis σ un psihometriskās līknes viduspunkta vērtība x_0, kas ir atkarīga no apgaismojuma (p<0,05). Skotopiskos apstākļos nepieciešama mazāka krāsu diference, lai novērotu stereoskopisko efektu.
Atslēgas vārdi: krāsu stereoredze, dziļuma sajūta, krāsaini stimuli, hromatiskās aberācijas
Bachelor thesis is written on 37 pages by computer in Latvian. It contains 22 figures,1 table, 3 appendix. There are 28 references to literature sources. Aim: To research depth perception induced by chromostereopsis and detection threshold depending on the lighting and change of the stereoscopic effect when field of the vision is partly obscured. Method:Assessment test of chromostereopsis (a computer program) consisting of peripheral and central squares with chromatic difference of purple colour. Conclusions: Chromostereopsis can be described by the detection threshold σ and psychometric curve midpoint value x_0, which is dependent on the light (p <0.05). Scotopic conditions require less color difference in order to observe the stereoscopic effect. Keywords: chromostereopsis, depth perception, chromatic stimuli, chromatic aberrations
