Abstract: An evaluation method of craniofacial asymmetry index based on artificial intelligence is disclosed and includes: a craniofacial image shooting step: obtaining a craniofacial model file of a patient; an artificial intelligence head shape identification and feature point marking step: importing the craniofacial model file into an artificial intelligence algorithm, performing identification and feature point marking on a craniofacial image in the craniofacial model file to generate at least one feature point; a craniofacial space coordinate axis establishment step: including a coordinate axis y-z plane establishment step, a coordinate axis origin establishment step and a z-axis orientation definition step; and an artificial intelligence skew degree estimation step: inputting the craniofacial model file and corresponding coordinate axes into an artificial intelligence skew degree evaluation algorithm simultaneously, and presenting a craniofacial skew degree in a data visualization manner.

Abstract: An optical fiber strip has a stair-shaped base element, a cover element, an adapter and an internal optical fiber array. The stair-shaped base element has a plurality of holes and a first bearing surface. The holes are integrally formed and extends from the first receiving surface to a bottom surface of the stair-shaped base element. The cover element includes an internal curved space between the first curved part and second curved part. The internal optical fiber array is selectively and optically coupled to tan optical-electrical conversion unit via the holes. A curved portion of the internal optical fiber array is located in the internal curved space for changing direction of the internal optical fiber array.
