Worker Position Detection With Brightness-Adjusted Overhead Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing worker position detection systems in production sites require users to provide both captured images and information, lacking a mechanism to automatically output worker positions and adjust image brightness for improved visibility.
Innovation Solution
A detection system that includes an image acquisition unit, partial image detection, position information acquisition, adjustment information acquisition, and output unit to display worker positions with brightness-adjusted images, utilizing a camera with a vertically downward imaging direction and incorporating GUI for parameter adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a camera system is used to detect worker position, then the need for carrying devices is eliminated, but the captured image brightness may be insufficient for clear visibility
Solution Approach 1:
The patent introduces an image processing unit that acts as an intermediary between the camera and the user. This unit receives captured images and applies brightness adjustment processing to enhance visibility while preserving the original detection capability, thus resolving the contradiction between ease of operation and illumination intensity.
Solution Approach 2:
The patent changes the brightness parameter of captured images through processing. By adjusting the brightness parameter in the image processing unit, the system maintains the original detection function while improving image visibility for users.
2Measurement precision
If captured images are provided for work analysis, then position detection accuracy is improved, but user interaction for parameter adjustment becomes complex
Solution Approach 1:
The system provides self-service functionality where the image processing unit automatically performs brightness adjustment based on captured images. This reduces the need for complex manual parameter adjustments while maintaining detection accuracy, as the system serves itself by automatically optimizing image parameters.
Solution Approach 2:
The patent performs preliminary brightness adjustment processing on captured images before they are displayed or analyzed. By pre-processing the images to optimize brightness, the system reduces the need for subsequent manual adjustments, thereby simplifying the user interface while maintaining precision.
3Illumination intensity
If brightness adjustment is applied to captured images, then image visibility is enhanced, but the system requires additional processing steps
Solution Approach 1:
The patent merges the brightness adjustment function with the existing image processing pipeline. By integrating the brightness enhancement into the overall image processing workflow rather than adding a separate complex subsystem, the system enhances visibility while minimizing the increase in device complexity.

AI summary
A method includes: a step of acquiring a captured image of a workplace captured by a camera that is installed above the workplace and has an imaging direction substantially vertically downward; a step of detecting a partial image representing a wearing object worn by a worker from the captured image acquired; a step of acquiring position information indicating a position where the partial image is detected in the acquired captured image; acquiring, for the acquired captured image, adjustment information for displaying the captured image in which brightness is adjusted; and outputting, for the acquired captured image, the position information acquired from the captured image and the adjustment information acquired for the captured image.
