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: An instrument for dynamically observing the evolution behavior of the slope topography. The dual hosts emit parallel, equal-height and overlapped laser planes from different directions, and project the laser planes onto a slope landform. The image acquisition device shoots the slope landform with the projected laser lines at an angle perpendicular to the laser-planes. Then a video screenshot can be formed and imported into a computer to form a three-dimensional map. Finally, the volume, slope gradient and other parameters of the slope body can be obtained. As the knobs on the mechanically micro-adjustable host of the topography meter are turned, the laser-planes can become precisely equidistant and parallel. A novel topography meter is disclosed, which can conveniently calibrate the spacing and angle of the linear lasers and accurately observe all landforms including the local deep trenches on an eroding slope.

Abstract: The invention belongs to the field studying the devices for soil and water conservation. The invention involves a topography-meter host based on integrative mainboards, which dynamically observe the landform in real-time and three-dimensions. The linear laser sources are accurately positioned with Ohm-shaped clamps, so as to emit parallel and equidistant laser-planes projecting onto a terrain in an experiment. The positions of the laser-sources on the mainboards are fixed with the Ohm-shaped clamps. The clamps do not only realize the convenient adjustment of the emission angle and spacing distance of the adjacent laser-sources, but also ensure a high accuracy of the positions and angles of the laser-sources even if the topography-meter host is moved. Several multi-segmented cases are freely spliced to observe the landforms with different heights in real-time.
