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. The entire device uses a sheet metal shell and internal frame as its base, minimizing the weight of the components. In addition, all power components use ultrasonic motors with stronger positioning and stopping performance, greatly improving the accuracy of the print head operation. The two-axis main body carrying the three axes uses an air-suspended linear guide, which greatly reduces the friction of the three axes and further improves the response speed of the print head. The entire device is lightweight and occupies less space, with a faster printing speed and significantly improved accuracy compared to ordinary printers.

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.
