Abnormal Part Display Using Point Clouds and Photo Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for specifying abnormal parts in objects using laser ranging data lack sufficient color information, leading to poor visibility and difficulty in intuitively understanding displayed data.
Innovation Solution
Integrate laser ranging data with photograph images on a shared screen, controlling the display to enhance visibility by selecting images based on brightness, weather, and time of capture, ensuring the integration of relevant color information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If point group data from laser ranging apparatus is displayed alone, then shape information is provided, but color information is scarce and visibility is poor
Solution Approach 1:
The patent combines point group data from the laser ranging apparatus with photograph images from the photographing apparatus into a single integrated display. The point group data and photograph image are superimposed or displayed together, allowing users to simultaneously view both shape information (from point group data) and color information (from photograph image), thereby resolving the information loss and visibility issues.
2Adaptability or versatility
If multiple photograph images are stored for different conditions, then color information availability improves, but selecting the appropriate image becomes complex
Solution Approach 1:
The control apparatus uses brightness information as feedback to automatically select the most appropriate photograph image for display. When point group data is acquired, the control apparatus refers to the brightness information associated with stored photograph images and selects the image with suitable brightness levels, eliminating the need for manual selection and simplifying the user interface while maintaining adaptability to different lighting conditions.
3Adaptability or versatility
If photograph images with varying brightness are displayed, then adaptability to different conditions improves, but visibility and user understanding deteriorate
Solution Approach 1:
The control apparatus changes the selection parameter (brightness level) when choosing photograph images for display. By evaluating the brightness information of stored images and selecting only those with appropriate brightness levels, the system ensures that displayed images have optimal visibility and are easy to understand, while still adapting to different acquisition conditions through selective display rather than displaying all available images.
