Solution Overview
Problem
Current three-dimensional image processing systems face challenges in reducing data transfer loads and achieving real-time processing due to the need for high-resolution pattern projected image data, which increases communication time and hardware costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution pattern projected image data is used to improve measurement precision, then measurement precision is improved, but data transfer load increases and communication time increases
Solution Approach 1:
The system divides the image processing into two segments: the head section captures and pre-processes images locally, while the controller section performs final processing. By segmenting the processing tasks, the head section can reduce the amount of data transmitted to the controller section, thereby reducing communication time while maintaining measurement precision through local pre-processing of pattern projected images
Solution Approach 2:
The head section performs preliminary actions by capturing pattern projected images and generating distance images locally before transmitting data to the controller section. This preliminary processing reduces the data volume that needs to be transmitted, addressing the contradiction between maintaining measurement precision and reducing communication time
2Measurement precision
If high-resolution pattern projected image data is used to improve measurement precision, then measurement precision is improved, but hardware requirements and costs increase
Solution Approach 1:
The system segments processing functions between the head section and controller section. The head section handles image capture and initial distance image generation with moderate hardware requirements, while the controller section handles final processing. This segmentation allows achieving measurement precision without requiring all high-performance hardware components to be present in the entire system, thereby reducing overall hardware requirements and costs
Solution Approach 2:
The head section creates a simplified representation (distance image) of the captured pattern projected images and transmits this copy to the controller section for final processing. By working with this compressed representation rather than the full-resolution original images throughout the entire system, the patent reduces hardware requirements while maintaining measurement precision
3Measurement precision
If pattern projected images are captured multiple times to improve measurement precision, then measurement precision is improved, but data transfer load increases
Solution Approach 1:
The head section performs preliminary processing by capturing multiple pattern projected images and generating distance images locally before transmission. By performing this preliminary action, the system can reduce the data transfer volume by transmitting only the processed distance images rather than the raw captured images, while still maintaining measurement precision through the multiple captures
Solution Approach 2:
The head section extracts essential information from the multiple captured pattern projected images by generating distance images that represent height information. This extraction process concentrates the critical measurement data into a more compact format, reducing the quantity of data that needs to be transferred while preserving measurement precision
