  • Publication number: 20230033542
    Abstract: The invention presents a system and a method for 3D human reconstruction using a compact kit of depth cameras. Instead of using complex and expensive devices as in traditional methods, the proposed system and method employs a simple, easy-to-install system to accurately collect the human body shape. The generated model is capable of moving thanks to a skeleton system simulating the human skeleton. The proposed system includes four blocks: Data Collection Block, Point Cloud Standardization Block, Human Digitization Block and Output Block. The proposed method includes five steps: Point Cloud Collecting, Point Cloud Filtering, Point Cloud Calibrating, Point Cloud Optimizing and 3D Human Model Generating.

  • Patent number: 11563261
    Abstract: The invention proposes a four-port coupler using micro-strip line in combination with ultra-wide-band compensation circuits. It can be applied for communication systems or information machine systems. The main feature of the invention is the structure and the distribution of the components in the compensation circuit to reduce the size of the coupler. The proposed coupler includes: microstrip directional coupler and compensation circuits, in which the microstrip directional coupler consists of one main line and two secondary transmission lines; the main transmission line has two ports: input and output ports; each secondary is connected to a load and a compensation circuit. The compensation circuit is composed of a low-pass filter and two parallel attenuation regulator circuits.

  • Publication number: 20230005231
    Abstract: The Invention presents a system and a method for digitizing a human body shape from anthropometrical measurements. The proposed system and method allow reconstructing the 3D human body quickly and accurately, improving disadvantages of costly and timely traditional methods, which not only requires digitized persons to be naked or wear tight clothes but also could use hazardous lights to their health. The system in the invention includes two main modules and two supplementary blocks to reconstruct the 3D human body from anthropometric measurements, which are: (1) Input Block, (2) Pre-Processing Module, (3) Optimization Module, (4) Output Block. The method in the invention includes four steps: (1) Step 1a: collecting human body measurements, (2) Steps 1b: Initial Population; (3) Step 2: Optimizing; (4) Step 3: Displaying digitized human body shape.
