Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LED display cabinet calibration methods are time-consuming and labor-intensive, requiring manual placement and data collection for each cabinet, which limits efficiency and accuracy, especially when dealing with large orders and multiple cabinets.
Innovation Solution
A luminance-chrominance calibration production line that uses multiple image acquisition apparatuses to collect color image information in a pipelined manner, allowing simultaneous calibration of multiple LED display modules and reducing manual labor, with an automated rail system and networked computers for efficient data processing and coefficient generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual placement and data collection for each cabinet is used, then calibration accuracy can be maintained, but calibration time and labor requirements increase significantly
Solution Approach 1:
The calibration system is segmented into multiple independent image acquisition apparatuses, each capable of independently capturing images of LED cabinets. This segmentation allows parallel processing of multiple cabinets simultaneously, dramatically improving calibration efficiency while maintaining accuracy through consistent imaging procedures across all apparatuses
Solution Approach 2:
The manual mechanical placement process is replaced with an automated rail system that transports LED cabinets to predetermined positions. This substitution eliminates manual intervention in positioning, reducing labor requirements and time consumption while ensuring consistent, accurate positioning through automated control mechanisms
2Ease of operation
If multiple persons are used for carrying and calibrating cabinets, then operational flexibility is maintained, but time consumption increases
Solution Approach 1:
The system enables self-service operation where the automated rail system independently handles cabinet transport and positioning without requiring multiple persons to manually carry and position each cabinet. The coordinated operation of multiple image acquisition apparatuses further automates the data collection process, significantly reducing both labor requirements and calibration time
3Device complexity
If sequential calibration of cabinets is performed, then resource requirements are reduced, but overall production speed decreases
Solution Approach 1:
Multiple image acquisition apparatuses are merged into a single coordinated calibration system, allowing simultaneous calibration of multiple LED cabinets. This merging enables parallel processing where several cabinets can be calibrated at the same time, dramatically increasing production speed while the shared use of computing and processing resources keeps system complexity manageable

AI summary
A luminance-chrominance calibration production line includes: a rail; multiple stations disposed along the rail and including multiple first darkroom stations; multiple image acquisition apparatuses respectively disposed in the first darkroom stations and for capturing different color images sequentially displayed by a to-be-calibrated LED display module loaded on the rail to acquire color image data; and a rail computer system for controlling a transport movement on the rail and controlling the to-be-calibrated LED display module to display the different color images, and being signally connected to the image acquisition apparatuses to obtain the color image data. By using multiple image acquisition apparatuses to collect various color image information of LED display module in pipelined manner, calibration efficiency is improved, data collection is accurate, data collection error caused by using different image acquisition apparatuses to calibrate different LED display modules is avoided and calibration manpower is reduced.
