The present invention relates to field of view matching for mobile 3D imaging (such as mobile C-arm 3D imaging). In order to provide improved image data for comparison purposes, for example when using a mobile X-ray imaging system, first position information of a first reconstructed volume that receives a first sequence of X-ray images of a region of interest of a subject acquired along a first trajectory in a first position of an X-ray imaging device is received. In addition, a planned second trajectory for acquiring a second sequence of X-ray images in a second position of the X-ray imaging device is received, and a generated second reconstructed volume for the second sequence of X-ray images is calculated. Then, second position information for the second reconstructed volume is determined. In addition, based on the first position information and the second position information, a degree of comparability between the first reconstructed volume and the second reconstructed volume is determined. An adjusted second trajectory is calculated, which results in an increased degree of comparability between the first reconstructed volume and the second reconstructed volume. The adjusted second trajectory is used to acquire the second sequence of X-ray images in the second position of the X-ray imaging device.

A lightweight, highly mobile 3D printer driven by an ultrasonic motor, belonging to the field of equipment technology in materials manufacturing, includes a lightweight frame axis, a two-axis air suspension system, and a three-axis printing and lifting system. The lightweight frame axis serves as the equipment base and is installed at the bottom layer along with the finished product ejection platform. Its internal power frame, based on a simplified skeleton, provides the track and power for the upper components to move back and forth along the Y-axis. The two air suspension axes are mounted on the lightweight frame axis and can move freely along the Y-axis. Their main body is a set of customized air suspension linear guides, used to provide the track and power for the upper components to move left and right along the X-axis, and significantly reduce friction generated during upper component displacement. The three printing and lifting axes are mounted on the air suspension tracks. The two axes can move freely along the X-axis, while the built-in self-heating print head can move freely up and down along the Z-axis, melting and stacking the printing material.

A system and method for quality-controlled three-dimensional volumetric measurement on mobile or head-worn devices. During acquisition, the device evaluates quantitative scan-quality metrics in real time and provides corrective guidance to address deficient regions. An on-device acceptance gate prevents export until thresholds for coverage, alignment, motion stability, and volumetric uncertainty are satisfied. Following validated capture, the system generates a watertight surface model, computes volume with quantified standard uncertainty, and records the quality context supporting acceptance. Follow-up scans are registered to a baseline so that longitudinal changes are judged against propagated uncertainty, enabling statistically reliable alerts. On devices lacking hardware depth, scale is stabilized by fusing visual-inertial mapping with anthropometric priors. The validated result, including volume, uncertainty, quality indicators, and device provenance, is digitally signed and packaged as an interoperable artifact for integration with electronic health record and remote-monitoring systems.

This invention relates to the field of computer vision, and more particularly to a mobile 3D human pose estimation method and system based on collaborative processing. The method involves acquiring three consecutive frames: the current frame and its adjacent preceding and following frames. Feature extraction is performed on the current frame at a first depth, and on the preceding and following frames at a second depth, where the second depth is less than the first depth. Based on the extraction results, the features extracted from the three frames are fused to obtain image features with fused temporal information. These fused temporal information image features are input into a pre-defined staged localization model. The model sequentially performs first-stage localization and second-stage localization, and outputs the execution results. Based on the output results, the initial position and fine-tuning are processed to determine the coordinates of key points in the 3D human pose. The input is into a two-stage localization model employing a coarse-to-fine strategy; this collaborative mechanism balances the conflict between accuracy and speed.
