Marker Image Scanning for Low-Load Mobile Body Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile body control systems face high image processing loads when markers cannot be imaged from the front, particularly when the marker's image width or height is short, leading to inefficient detection and processing.
Innovation Solution
The system employs a multi-scanning approach with first, second, and third scanning units to determine specific conditions based on image patterns, allowing for marker detection without increasing processing load, using a matrix-shaped marker with reflective and light absorption cells to guide the mobile body's operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is performed to generate a corrected image when the marker cannot be imaged from the front, then the marker detection capability is improved, but the processing load of the image processing device increases
Solution Approach 1:
The image processing is segmented into multiple scanning units (first scanning unit, second scanning unit, third scanning unit) that scan different areas of the image in different directions. Each scanning unit processes only a specific portion of the image, dividing the overall processing load into manageable segments that can be handled independently.
Solution Approach 2:
Instead of processing the entire image to generate a corrected image, the system performs partial scanning of specific areas (first area, second area, third area) that are most likely to contain the marker. This partial action approach reduces processing load while maintaining detection capability.
2Measurement precision
If the marker image width or height is short, then the marker may be missed in conventional scanning, but increasing processing to handle all cases increases the processing load
Solution Approach 1:
The system scans the image in multiple directions (first direction, second direction) rather than only in one direction. This multi-dimensional scanning approach ensures that markers with short width or height in one direction can still be detected by scanning in perpendicular or different directions, improving detection accuracy without requiring complex image correction processing.

AI summary
An image processing device includes: a first scan of first area of an image acquired on the basis of reflective light of light emitted to the outside of a mobile body in first direction; a first determination of whether or not a first condition is satisfied on the basis of result by the first scan; a second scan of second area of the image in second direction different from the first direction in a case in which the first determination determines that the first condition is satisfied; a second determination of whether or not a second condition is satisfied on the basis of result by the second scan; a third scan of third area of the image after the second determination determines that the second condition is satisfied; and a third determination of whether or not predetermined information is included in the third area scanned by the third scan.
