Gazodizellar silindrlar gilzalari ishchi yuzasini kontaktsiz optik tizimlar yordamida nazorat qilishda yuqori aniqlikdagi uch o‘lchamli modellarini qurish asosida yorug‘lik namunalarini proeksiyalash va qayd etish jarayonlarining qatʼiy matematik tavsifi yotadi. Strukturallashgan yorug‘lik usuli optik triangulyatsiya tamoyillariga asoslangan bo‘lib, bunda tadqiq etilayotgan sirt nuqtalarining fazoviy koordinatalari strukturallashgan yorug‘likning geometrik buzilishlarini tahlil qilish orqali aniqlanadi. Ushbu jarayonni matematik shakllantirish uchun o‘lchov tizimining geometriyasini, yorug‘lik intensivligi taqsimoti tenglamalarini, shuningdek, faza ma’lumotlarini dekodlash algoritmlarini batafsil ko‘rib chiqish talab etiladi. Mazkur maqolada proyeksiyalanadigan chiziqlarning ikki o‘lchamli buzilishlarini obyekt sirtining uch o‘lchamli (X, Y, Z) koordinatalariga aylantirishni tavsiflovchi asosiy matematik qonuniyatlar va analitik bog‘liqliklar keltirilgan.
