Abstract: This disclosure describes systems and techniques for synchronizing cameras and tagging images for face authentication. For face authentication by a facial recognition model, a dual infrared camera may generate an image stream by alternating between capturing a “flood image” and a “dot image” and tagging each image with metadata that indicates whether the image is a flood or a dot image. Accurately tagging images can be difficult due to dropped frames and errors in metadata tags. The disclosed systems and techniques provide for the improved synchronization of cameras and tagging of images to promote accurate facial recognition.

Abstract: According to an aspect, a method may include receiving two-dimensional (2D) positions of at least one of a first reflective marker or a second reflective marker of a physical component, estimating a three-dimensional (3D) position of the first reflective marker and a 3D position of the second reflective marker based on the 2D positions, and computing an orientation of the physical component in 3D space based on the 3D position of the first reflective marker, the 3D position of the second reflective marker, and positioning information of the first and second reflective markers in the physical component.
