Abstract: An intraoral three-dimensional scanning system with a monocular camera includes the monocular camera. A first mirror and a second mirror perpendicular to each other are provided between the monocular camera and an object to be measured. A bisector of an angle formed by the first mirror and the second mirror is perpendicular to a lens of the monocular camera, and reflecting surfaces of the first mirror and the second mirror face the lens. A third mirror is provided at a side of the first mirror away from the second mirror, and a fourth mirror is provided at a side of the mirror away from the first mirror. The first mirror, the second mirror, the third mirror and the fourth mirror are located in the same plane.

Abstract: A next generation sequencing (NGS) based method includes applying, for one or more genetic loci, respective NGS data for genotype of a first subject, genotype of a second subject, and genotype of an alleged offspring of the first and second subjects to a statistical model calculating a value representing a likelihood the offspring is a true offspring of the first and second subjects. The NGS data includes genotype and sequencing read of the first tested subject; genotype and sequencing read of the second tested subject; and genotype and sequencing read of the alleged offspring. The statistical model utilizes a probability of the genotype of the first tested subject in a subject population; a probability of the genotype of the second tested subject in a subject population; and a probability of the genotype of the alleged offspring in a subject population.
