Solution Overview
Problem
Current additive manufacturing technologies face challenges in producing complete three-dimensional solid geometric models due to holes or shadows in three-dimensional image data obtained from scans, affecting the similarity of reproduced objects.
Innovation Solution
A 360-degree three-dimensional modeling method and system that performs a 360-degree scan on an object, registers and processes scan data to construct compensated-template model data, and fills unknown areas using morphing model data from a database, ensuring accurate and complete model reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current scan technology is used to produce three-dimensional solid geometric models, then the additive manufacturing process can be implemented, but holes or shadows will exist in the three-dimensional image data, making it impossible to obtain an entire and complete three-dimensional solid geometric model
Solution Approach 1:
The patent divides the three-dimensional scanning process into multiple regional scan areas, collecting data from different angles and positions. This segmentation approach allows comprehensive coverage of the object surface, ensuring that no areas are missed and enabling complete model reconstruction by combining multiple partial scans.
Solution Approach 2:
The patent performs preliminary registration and morphing processes on scan data before final model construction. By pre-processing the data to align and integrate regional scans, the system prepares complete three-dimensional image data in advance, eliminating holes and shadows before the additive manufacturing process begins.
2Manufacturing precision
If regional scan data is collected from multiple scan areas, then more complete coverage is achieved, but the complexity of data registration and processing increases
Solution Approach 1:
The patent introduces a control unit as an intermediary that coordinates multiple image capturing devices and manages data flow. This central control mechanism simplifies the complexity by providing a single point of coordination for registration and integration processes, rather than requiring complex peer-to-peer communication between multiple devices.
Solution Approach 2:
The patent designs the image capturing system with multiple devices that can perform both scanning and registration functions. The same hardware infrastructure is used for multiple purposes: capturing regional scan data, performing initial alignment, and providing reference data for morphing processes, thereby reducing overall system complexity.

AI summary
A three-dimensional modeling method and a three-dimensional modeling system are provided. The three-dimensional modeling method includes the steps of: performing a 360-degree three-dimensional scan on a measured object to obtain regional scan data corresponding to a plurality of different scan areas of the measured object; registering the regional scan data to form 360-degree three-dimensional scan data, wherein the 360-degree three-dimensional scan data include three-dimensional spatial coordinate data, curvature data and scan area data of the measured object; basing on the 360-degree three-dimensional scan data to search morphing model data from a database unit; a step of comparing the 360-degree three-dimensional scan data and performing registering and morphing processes on the morphing model data to construct compensated-template three-dimensional model data; and, basing on the compensated-template three-dimensional model data to fill at least one unknown area of the 360-degree three-dimensional scan data.
