Camera Alignment Check Using Color-Coded Image Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for checking camera alignment in industrial environments require position markers and are cumbersome, especially when the device is replaced or repositioned.
Innovation Solution
A method for checking camera alignment using a stored reference image and a current image, both displayed in monochrome with complementary colors, allowing for image mixing to visually assist in determining alignment without markers, facilitating repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position markers are used to check camera alignment, then alignment accuracy is improved, but device complexity and ease of operation deteriorate due to the need for additional markers and cumbersome procedures
Solution Approach 1:
The patent uses color-coded overlays that are superimposed on the captured image to represent the reference alignment position. Instead of physical position markers, the system creates a visual copy of the correct alignment state through colored transparency layers, allowing operators to compare current alignment with reference alignment directly on the display device.
Solution Approach 2:
The patent employs different colors (first color for reference image, second color for current image) to differentiate between reference alignment and current alignment states. The color mixing effect when overlays coincide provides immediate visual feedback about alignment accuracy, eliminating the need for complex marker-based measurement systems.
2Measurement precision
If position markers are used for camera repositioning, then alignment precision is improved, but time consumption increases due to the need to reattach or reference markers
Solution Approach 1:
The system stores reference alignment information as digital overlay data that can be instantly retrieved and displayed. When repositioning the camera, the operator simply captures a new image and superimposes the stored colored reference overlay, eliminating the time-consuming process of physically reattaching or referencing position markers while maintaining precise alignment.
Solution Approach 2:
The reference alignment overlay is prepared and stored in advance during the initial correct positioning of the camera. This preliminary action creates a reusable visual guide that can be instantly applied during any repositioning event, saving time by eliminating the need to重新 establish alignment references.
3Ease of operation
If color-coded overlays are used for alignment checking, then ease of operation is improved, but manufacturing precision requirements worsen due to the need for accurate color mixing and overlay alignment
Solution Approach 1:
The patent replaces physical mechanical alignment systems (position markers, manual measurement tools) with a digital image processing system. The colored overlays are generated and positioned computationally based on the captured image coordinates, eliminating the need for high-precision mechanical manufacturing of physical alignment aids while maintaining ease of operation.
